Ethernet on STM32F4DISCOVERY using external PHY
For you who have read about the STM32F4 Cortex-M4 processor you might know that this processor family includes a 10/100 Ethernet MAC with dedicated DMA that supports supports IEEE 1588v2 hardware, MII/RMII.
This means that the only electronics needed to enable the ethernet capability is an external PHY and the Magjack connector.
On the STM3240G-EVAL evaluation board the DP83848 PHY is used and luckily for us we were able to find a simple breakout board for this chip on eBay.
To hook up this Phy to the STM32F4DISCOVERY board a slight change in the pins, compared to the connections on the evaluation board, had to be made. Because the STM32F4DISCOVERY board only contains the 100-pin version some of the full MII pins are missing so we have to use the PHY in RMII mode.
So by taking the example project files for the Webpage example on the evaluation board, changing the GPIO initialization and Ethernet BSP file a bit to match the Discovery board, we were able to get the example running on our board.
The connections between the PHY module and the STM32F4DISCOVERY board can be seen in the image below.
On the PHY Breakout board there is space for a jumper. This jumper is used for external reset and should not be installed to work in this project.
To see the Ethernet functionality in use with the webpage example loaded on the Discovery board have a look at our video below.
The GCC project for the Webpage demonstration on the STM32F4DISCOVERY board, shown in the video, together with a CooCox CoIDE project file can be downloaded from the following link: STM32F4DISCOVERY Ethernet-Phy – Webpage example
Update 14. december 2017: Due to several problems in opening this old project in the more recent versions of CooCox CoIDE I have decided to migrate the project into the System Workbench IDE which both ST and I recommend using for new STM32 projects at the time of writing. The migrated project, which should be identical to the other one, can be downloaded from: STM32F4DISCOVERY Ethernet-Phy – Webpage example project for System Workbench
Thanks to a comment from @P_K there is a very simple way to generate your own new HTML files using the “makefsdata.exe” file found inside the “STM32F4x7_ETH_LwIP_V1.0.0\Utilities\Third_Party\PC_Software” folder.
Please read more about how to do so at the following page: http://www.aimagin.com/tgr/tgr12/amgf4connect/doc/HTML/index.html?webpage_configuration.htm
A comment from @Alex provides the following list with solutions to some of the problems that you might encounter when trying to setup this project and get it working:
- First of all, if you are getting problems to ping your PHY, please reduce your cables to 5cm. Your freq is really high and interference is something real to kill your tests!
- If you’re having problems at compile, make sure that your fsdata.c is out of your project to compile. You can find this file at “Ethernet/src”.
- Try to use Static IP for initials tests so, comment the line with #define USE_DHCP in main.c file. It will be a lot easier if your make a direct connection to your computer form your device and watch what is happening with the connection with Wireshark.
You can eventually also see the following forum post on how to get ChibiOS and their Ethernet example to work with the setup described in this post: http://forum.chibios.org/phpbb/viewtopic.php?f=3&t=23&p=8017#p8017
Nice, I tried the same thing with MII interface. I made own board with ethernet (DP83848) and LCD but it didnt work. Problem can be between magjack and PHY (probably bad PCB design)… I envy you 🙂
Hi Thomas,
You are using RMII, not MII. RMII is the name for reduced MII. RMII works with a 50 MHz clock rather than a 25 MHz clock for the MII mode. How do you generate this clock?
@Guillaume
Thank you for noticing. I have now changed the post.
About the clock there is a 50MHz oscillator on the Phy board we bought on eBay. Though the board can also be clocked externally if necessary – like for full MII.
Your project not run in my PC. I use CooCox CoIDE 1.2.4, open the project and try build, but I see “BUILD FAILED A pseudo attribute name is expected.” I don’t know what is wrong. Please help me. 😉
@P_K
Please update to the latest version of CoIDE. We are using CoIDE v 1.5.0!
Also which version of GCC are you using? We are using the GCC ARM Embedded v4.6 2012q2
When I used CoIDE v 1.5.0 and GCC ARM Embedded v4.6 2012q2 from your link, project was imported and was building, but in the end in console I saw “BUILD FAILED”. In Debug catalog was created 2 catalogs: “obj” and “bin”, but “bin” is empty and I don’t have file *.bin, *.hex …
@P_K
I have the same problem (COIDE 1.5 and GCC ARM Embedded v4.6 2012q2) !!!
I can send You log.
Regards
@P_K
What kind of error is it giving you in the Console?
“Build Failed” means that the compiler (GCC) returned an error, either in the compiling or linking stage.
So please write the exact error it is telling you.
@Andy
Please just write one of the error lines in here so I can try to track it down.
This will then also be more usefull for other readers if they experience the same error.
@Thomas Jespersen

Thank you for sending me the log.
The last lines in the log is the most importants, as they indicate the error! The others are only warnings.
The problem lies within the Project file as when saved, the excluded files is saved with the complete directory address (my local PC). So when downloaded to your PC to another directory/address than mine, the files that has to be excluded is no longer excluded.
The solution to the problem is to right click at the file “fsdata.c” found in the “Ethernet/source” folder in the Project list, and then select “Exclude from Build”.
Please let me know if it compiles then.
@Thomas Jespersen
Thanks for help.

How to change HTML sites ? Changes in fs Dir takes no effort.
regards
@Joerg
No, you can’t just change the files in the fs directory.
These files are just in there for demonstration purpose, as these files have been “cooked down” into the single “fsdata.c” file which contains the raw bytes of all the HTML content.
sir can you demonstrate how yo use cmsis-dsp libraries on cortex M4
@assad
Dear Assad.
We are actually working on getting the DSP library to work on the Cortex-M4 within the CooCox CoIDE environment (GNU GCC).
Though to get it working it requires that you recompile the cmsis-dsp library for the GNU GCC compiler, but by using Keil uVision etc.
We will hopefully soon make a guide about this.
How change whatever on HTML page? How “cook down” new changed page?
@P_K
Probably with a program that ST has made but not published. I don’t know.
It seems to me that it doesn’t come with the example, so it is no simple click-and-press solution to change the pages.
I found a simple solution. Take a look here: http://www.aimagin.com/tgr/tgr12/amgf4connect/doc/HTML/index.html?webpage_configuration.htm
@P_K
Ahh great. Thank you very much for that link.
any example stm32f4 through enc28j60 with keil mdk arm
What value should the voltage at pfbout have, if the phy works correctly? How much difference is allowed? The datasheet doesn`t give much information about it. Thx
GREAT!!! You made my day! I’m just thinking about burst up of my F4 to control some equipment thru ethernet.
@impacty
I don’t know about the expected voltage of the PFBOUT pin and I haven’t tried measuring it either.
Are you asking because you are having some troubles?
@Heru
Dear Heru.
I don’t have any examples for Keil, but I have made an ENC28J60 test application for the STM32F4 within Atollic TrueStudio.
That project including the ENC28J60 library can be found here: http://www.tkjelectronics.dk/uploads/STM32F4_SPI_Ethernet.zip
Please notice that this code is not finished yet and therefor not released into the public (on our Github).

Hi Thomas,
I think You are the right man for make that running. Based on the Sample from ST Dennis added SD Card and a lot of other tings to the server. But he has no Project settings.

helloo
i just have a question ,i used to follow this direction http://www.aimagin.com/tgr/tgr12/amgf4connect/doc/HTML/index.html?webpage_configuration.htm
but it didn’t work but i tried your project and i programmed your hex file and it does work , but your project file is not for keil , how can i open it? which compiler did u used?
thank you
Hi Thomas!
Nice work!
I wold like to try the same with another PHY but I am really beginner and could not.
I downloaded your CooCox CoIDE project, compiled and
programming the stm32f4discovery succesfully. I can see the
blinking led but the connection is not work.
I tried with dhcp and without
check the application from browser and from win7 cmd with ping command but there is
no answer
My ethernet phy is:

@Joerg
Dear Joerg.
Thank you for posting that link – I wasn’t aware of that source.
Would you mind zipping up your CoIDE project to save us the hassle when testing?
Then I will test it and if it works promising I will put it in the blog post too.
Thanks.

@Mahan
The project I’ve uploaded is actually a modified version of the ST released standalone httpserver – to be found in: “STM32F4x7_ETH_LwIP_V1.0.0ProjectStandalonehttpserver”.
In this ST release there is a Keil project file which you should be able to open.
To get the project working with the STM32F4DISCOVERY board just go grab the following two files from our project folder and put inside the ST released folder:
– “STM32F4x7_ETH_LwIP_V1.0.0ProjectStandalonehttpserversrcstm32f4x7_eth_bsp.c” replace with “OURSEthernetsourcestm32f4x7_eth_bsp.c”
– “STM32F4x7_ETH_LwIP_V1.0.0ProjectStandalonehttpserverincstm32f4x7_eth_bsp.h” replace with “OURSEthernetincludestm32f4x7_eth_bsp.h”
Let me know if it works for you.
Regards Thomas
@Peti
I see you have the LAN8720A PHY chip.
Unfortunately I have only worked with the DP83848 and the KS8721BL so I have no experience to share with you about your PHY.
Though thru what I have tried changing from one PHY to another shouldn’t be a difficult task as long as they work about the same (the internal registers), which most PHY’s do.
For you to get it working you should focus on getting the right PHY address, which is actually not the PHY address itself but a bus address telling the STM32F4 device where the Ethernet PHY can be found.
This code can be added to the bottom of the ETH_MACDMA_Config() function inside the stm32f4x7_eth_bsp.c to check for a valid LAN8720A PHY.
union {
uint32_t HI_LO;
struct
{
uint16_t LO;
uint16_t HI;
};
} PHYID;
for(PhyAddr = 1; 32 >= PhyAddr; PhyAddr++)
{
// datasheet for the LAN8720A ethernet controller (http://www.smsc.com/media/Downloads_Public/Data_Sheets/8720a.pdf)
// page 51-52 --> PHY Identifier Register 1 and 2
PHYID.HI = ETH_ReadPHYRegister(PhyAddr,2); // 0x0007
PHYID.LO = ETH_ReadPHYRegister(PhyAddr,3); // Mixed bits
if (0x0007 == PHYID.HI) break;
}
if(32 < PhyAddr)
{
//printf("Ethernet Phy Not Foundnr");
while (1);
}
BOARD_PHY_ADDRESS = PhyAddr;
/* Configure Ethernet */
EthInitStatus = ETH_Init(Ð_InitStructure, BOARD_PHY_ADDRESS);
Good luck.
Best Regards
Thomas Jespersen
I’ve made everything according connection scheme with the same PHY board and flashed my Discovery with your hex file from archive, but I can’t get connection (only orange led is blinking first time). In connection properties where are send packets, but no received packets. What can be wrong? I also installed Wireshark, and found only packets send by computer, not Discovery. Connection is established only if static IP is selected.
@DeusExMachina
everything is ok, it was too long wires
Hi,
I’m new in STM microcontrollers and I would like to ask if someone had similar problem with ethernet and LwIP stack: I simply took first example in LwIP (httpserver) and got problem->after some code corrections as mentioned above, when I compile and start debugging, everything works fine, I can open my own made page (made by using fsdata) on browser and etc., but after microcontroller reset ETH_CheckFrameReceived() never returns 1 and packets are not handled…Any ideas? Thx.
Oh, it was my mistake, I didn’t imagine how long could take DP83848 startup… the main problem was that stm32f407 starts mush faster and tries to initialize DP83848 while it’s not ready…small delay helped.
@vaidas
When resetting the microprocessor did you reset the DP83848 chip too by its’ reset pin?
If so, then yes, you will have to wait a couple of hundred milliseconds for it to restart.
But thank you for the information if we or any other run into similar issues.
@Thomas Jespersen
Yes, I was reseting DP83848 by reset pin, but at first didn’t put any delay after that (somehow I imagined that stm32f407 startup time is set to much longer), it’s just because this is my first STM microcontroller. It was very confusing, because I’ve made my own PCB and didn’t have hardware reset button on my board, that’s why I spent few hours for debugging this problem(after downloading program to flash, everything worked, but after turning off the board, it didn’t)… and just then I read full DP83848 datasheet and put delay…
Dear Thomas,
I have downloaded your project, and upload via CoIDE, but it can’t work. If I use DHCP mode, I get four “DHCP offer” messages at wireshark. So I think, Discovery board can send “DHCP Discover” to network.
If i don’t use DHCP, I get “02:00:00:00:00:01 Broadcast ARP 60 Gratuitous ARP for 192.168.0.111 (Request)” at wireshark.
So it can send message to network, but it can’t receive, I think… I am using 3 meters UTP cabel for connection, and ~10-15 cm wires to Discovery board.
Happy new year, and best wishes!
@DeusExMachina
What wires were too long? Between router and DP83848, or between Discovery board and DP83848? I am getting, what you get.. Board can send messages, but can’t receive 🙁
@Gabor
I guess(99%), that wires between Discovery board and DP83848, because internet cable can be 150 meters long with no errors. I don’t know, but I guess again, that if your wires between Discovery board and DP83848 board are long enough (~10cm) there could appear problems due to signal interference in neighbour wires and also appears significant capacity between wires and wire inductance…If u use discovery board, that means u use RMII interface, which is clocked by 50MHz, so clock’s period is T=1/50*10^6=20ns.
@vaidas
Thank you for your answer. So, what do I have to do? Do I have to use shorter wires, and that’s enough? In youtube video, which has been linked by Thomas to this site, looks like he uses “long” wires, and no problem.
@Gabor
Yes, these wires are long enough… but I would make them as short as possible, but maby problem is in different place…
I’ve just read your older post and you say that : “Board can send messages, but canâ??t receive”. How do u know, that board can send message? u told something about wireshark. Did u decide, that your board is alive from wireshark? Blinking led means that something is on the wire and doesn’t say which direction.I was compiling this project with MDK-ARM, but I think it’s everything the same. When I was debugging my ethernet hardware, I turned off DHCP by commenting define statement (USE_DHCP or similar), changed IP address into local’s network, for example 192.168.0.15, then manually configured my LAN card’s parameters to the same network, for example 192.168.0.12 and pinged my device with RUN-> CMD -> ping 192.168.0.15 . Another solution-> it’s known that web server uses TCP protocol and 80 port to communicate with your board. Even if you are not asking to download web application in your browser, your computer and Discovery board comunicates, when you just plug the cable(between board and computer)- it’s 3 steps handshake and if you will turn off your internet and filter packets in wireshark, u will see what is going on on the line. What I want to say is- maby everything is working, but u want to check communication in wrong methods.
Good Luck, keep working.
@Gabor
oh, and one more thing, u wrote, that ARP works on your board and your IP is 192.168.0.111, so everything works, that means, that your computer asks your board and it answers. If I misunderstood something in your post, just type in CMD: “arp -a”, and it shows all devices connected to your LAN cards (including wireless and virtual), if in one of lines you will find your mac :”02:00:00:00:00:01″ with IP, that definitely means that everything is OK with your card. And if u just don’t see that webserver on internet browser, check folder “ProjectStandalonehttpserverfs” if there is index.html file, maby you are compiling empty webserver page. Or your LAN and board is in different subnet…
@vaidas
“How do u know, that board can send message?” If I use DHCP mode, I get “DHCP Offer” from my router in wireshark.
According to DHCP protocol, 1) client send “DHCP Discover” to broadcast, and somebody will answer. So 2) my router answer “DHCP Offer”, but it repeats four times, because nobody (client) send answer, “DHCP request”.
I think, board can send messages, like “DHCP Discover”, but can’t receive, because it isn’t answer to router’s “DHCP Offer” message.
I tried to get devices with “arp -a” command, but I didn’t found board’s MAC address. Board just send “arp gratuitous” to broadcast.
I switched to fixed IP, like 192.168.0.111, and opened in webbrowser. I get ping timeout.
@Gabor
hmmm…very interesting…
1) do you see one led always on(when plug cable) and another blinking? if yes, that means your PHY chip is in normal mode, if not, it’s in reset state.
2) for arp’ing I recommend to use straight cable to your PC, without router, and configure manually your LAN card with something 192.168.0.100. Maby your PC and board are in different subnets, then ARP cannot find your board.
3) need to check wires, maby some mistake…
@vaidas
I made quickly a crossover cabel. Aaaand it works without router :), but sometimes throw ping timeout. I think, I have to optimize wires between board and ethernet module, and it will be better.
Thank you so much, best wishes!
@Gabor
And one more thing – you don’t need to change cable, auto-MDIX should handle this, because if DP83848 feels that something is wrong with cabling, it changes Rx logic with Tx logic and u don’t need to change cable(PC side or new routers acts the same way). And if you want to use your router, u have to change subnet in your board.
Yes, timeouts can appear because of long cables, if due to wires capacity and resistance (T=RC) some bits dissapear, when board checks CRC it doesn’t match and it throw packet to the trash bin… try to ping it in CMD and check how many percent of packages reach destination.
Glad could help.
Good luck in your future projects.
My ping from PC to STM is to high and is nearly 130ms. How to decrease this value?
@P_K
We are experiencing the same same issue – both with the Discovery board and the DP83848 Phy, but also with the Olimex board and the KS8721BLMM Phy.
I think it might have something to do with either the lwIP stack, the configuration of it or an issue with the NVIC interrupt processing on the STM32 processor.
The issue is still to be resolved!
Hi,

CASES that i have tried;
When i powered the module and the board i get the link led(orange one) always on and the data led(green one) blinking.
1)When i use “dhcp on” mode for the discovery board i couldn’t even ping or get the webpage on browser. In the wireshark screen i get “dhcp discover” lines for 4 times but no response from the router and discovery cannot get and ip.
“125 39.520406000 0.0.0.0 255.255.255.255 DHCP 350 DHCP Discover – Transaction ID 0xabcd0001”
2)When i use “dhcp off” mode no ping response and no webpage again.On the wireshark screen i get

but no response from the router.
3)When i dismiss the router and get connected the discovery and the computer with a straight ethernet cable(dhcp off mode for the board) i cannot ping the module and cannot reach the webpage.
In all cases i cannot see the board in the list for “arp -a” command. I checked the cabling 3-4 times so i dont think there is a mistake with it. I need some help and advice thanks in advance..

Hi,
I am using a phy from Micrel(KSZ8041NL) ,I have downloaded your code and made changes to the phy register values in the stm32f4x7_eth_conf_template.h file but the project is not working.I am using MII mode in this project.Help needed….
Thanks in advance….
hi everyone,
im using stm32f4 discovery board and dpxxxx as phy module. The changes i have made on the lwip example of st(standalone->httpserver example)
1) gpio alternative function definitions and initializations for PA1,PA2,PA7,PC4,PC5,PC1,PB11,PB12,PB13
2) Definition of HSE value as 8000000hz and pll_m value as 8
3) Moving the MCO pin (PA8) initialization inside the MII_MODE selection.
#ifdef MII_MODE /* Mode MII with STM324xG-EVAL */
#ifdef PHY_CLOCK_MCO
GPIO_Init(GPIOA, &GPIO_InitStructure);
/* Output HSE clock (25MHz) on MCO pin (PA8) to clock the PHY */
RCC_MCO1Config(RCC_MCO1Source_HSE, RCC_MCO1Div_1);
#endif /* PHY_CLOCK_MCO */
(Other GPIO configurations (pin,speed,mode,OType,PuPd) are outside this condition.)
4) Ethernet clocks is started after the software reset of ethernet.
/* Reset ETHERNET on AHB Bus */
ETH_DeInit();
/* Software reset */
ETH_SoftwareReset();
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_ETH_MAC | RCC_AHB1Periph_ETH_MAC_Tx |
RCC_AHB1Periph_ETH_MAC_Rx, ENABLE);
5)#define USE_DHCP and commented out version (//#define USE_DHCP) are both tried.
6)â?#define RMII_MODEâ? and â??//#define MII_MODEâ?
7)My Airties modems(also gateway) ip is 192.168.2.1
My PCâ??s ip is 192.168.2.20(no automatic ip , this is static on ipv4 settings)
The static ip defined on the code for the board is 192.168.2.27
The subnet of the network is 255.255.255.0
DHCP settings of the router start adress 192.168.2.20- end adress 192.168.2.30 and three computers are using the LAN(the last oneâ??s ip 192.168.2.22)
CASES that i have tried;
When i powered the module and the board i get the link led(orange one) always on and the data led(green one) blinking.
1)When i use â??dhcp onâ? mode for the discovery board i couldnâ??t even ping or get the webpage on browser. In the wireshark screen i get â??dhcp discoverâ? lines for 4 times but no response from the router and discovery cannot get and ip.
â??125 39.520406000 0.0.0.0 255.255.255.255 DHCP 350 DHCP Discover — Transaction ID 0xabcd0001â?³
2)When i use â??dhcp offâ? mode no ping response and no webpage again.On the wireshark screen i get
02:00:00:00:00:00 Broadcast ARP 60 Gratuitous ARP for 192.168.2.27 (Request)
but no response from the router.
3)When i dismiss the router and get connected the discovery and the computer with a straight ethernet cable(dhcp off mode for the board) i cannot ping the module and cannot reach the webpage.
In all cases i cannot see the board in the list for â??arp -aâ? command. I checked the cabling 3-4 times so i dont think there is a mistake with it.I have tried all of the configurations with cross and straight ethernet cables. I need some help and advice thanks in advance..

@kadir4172
plug your board straight to PC, check pinout one more time and put long delay after your ethernet chip in main(20-100ms), disable DHCP and make sure, that you are in the same subnet as your board is(maby you ar checking wireless card’s IP, not cable ethernet card?) my pin configuration looks like this:

I have found a similar problem. I am working on STM32F407 + DP83848 + LwIP.
However I have looking in the data packet with wireshark.. and comparing with another DHCP packet (the valid, and working.
I have Looked on BOOTSTRAP Protocal . and saw that the “Bootp flags” was 0x000 which is unicast.
from my understanding , I should be “BROADCAST” , 0x8000.
then I checked line 845 in “dhcp.c” in the driver ,
dhcp_option_byte(dhcp, DHCP_OPTION_BROADCAST);
it said “BROADCAST” with
#define DHCP_OPTION_BROADCAST 28
in dhcp.h.
Dose it a bug? or something? Is my understanding correct?
Furthermore the packet size is larger than another computer’s packet.
STM32F4+LwIP generates 350Bytes Packet, But another working computer generates 350 Bytes DHCP Discovery Packet.

Will this code compile on keil uvision?

what might be the problem?
thomas u are awesome man!!
Can you explain your words : “Because the STM32F4DISCOVERY board only contains the 100-pin version some of the full MII pins are missing so we have to use the PHY in RMII mode.”. Which of the pins are missing? In my opinion every pins are available in 100pins STM32F4 version on STM F4 Discovery.

How to refresh HTML page with use user button on the board?
@P_K
You would have to elaborate on what you mean by “refresh”.
Do you want to change the content of a page when pressing the button, or would you like the page to be refreshed inside of the external browser when the button is pressed?
@Thomas Kaiser
I am currently still running CoIDE 1.5.1 due to some project structure changes in 1.6.0.
In my version I am able to right click on the file in the left file-structure panel and select “Exclude from Build…”

@Thomas Jespersen
Hi,
Thanks for the project.
I am having the same problem with the error:
[cc] collect2: ld returned 1 exit status
BUILD FAILED
I am using CoIDE V1.7.2, when I right click on the file â??fsdata.câ? I don’t get the â??Exclude from Buildâ? option. Is there a new way to exclude the file from the build that I’m missing, sorry I’m a total newby with CoIDE and STM32F4.
Your assistance would be much appreciated.
Regards,
Dean.
@Dean
Yet again the problem has to do with the CoIDE version, as they have removed the ‘Exclude’ option after V1.6.0!
You can try and delete the file ‘fsdata.c’. If not that works you need to downgrade you CoIDE version and inatall 1.5.1 instead.
Regards Thomas
@Thomas Jespersen
Hi Thomas,
Yes, I found on the CoIDE help forum that they had removed the ‘exclude’ option (a few people are asking for it to be put back in) so I deleted the ‘fsdata.c’ file from the project, it just deletes the link to the file not the file itself. So now I can get the project to compile in CoIDE V1.7.2.
I am getting a lot of warnings along the lines of “warning: format ‘%u’ expects argument of type ‘unsigned int’, but argument 3 has type ‘u32_t'” probably not too much to worry about but I do prefer to get a ‘clean’ compile without warnings where I can.
I actually have the STM32F4-Base board which has the DP83848 phy chip not the LAN8720 described in this project so I suppose I now need to modify the project back to the original demo files to get it to work with the DP83848.
Thanks for your help.
Regards,
Dean.
@Dean
Glad you worked it out.
You can safely ignore those warnings as an unsigned int corresponds to the same as a u32 when compiled.
Regards Thomas
Hi Thomas,
What was the code size that you had for this project?
I am using the firmware example from STM but that has a size of around 42kB and the limit for the software tool is 32kB.
Regards,
Saurav
@Saurav
I am using CooCox CoIDE to compile this project.
This compiler is a free compiler without any limitations, so which kind of limitation are you referring to? Debugging?
Regards Thomas
@Thomas Jespersen
Yes, I am referring to the debugging limit. I am currently using Keil uV4. I am actually implementing just an echo server to start off with. What I did was to comment out the glcd sections of the code and remove the .h file for the same. I was able to get it below 32kB.
@Thomas Jespersen
Now however, I am stuck with an unreachable destination host when I use Ping.
Note that I am able to run my debug session on uV. So the board is definitely alive.My setup is like this:
Main board: Discovery kit with the 407VG controller.
Base Board from STM with a 8270 PHY.
USB to miniUSB between my system and the discovery board.
LAN cable between my system and the discovery.
I am using the default ping command (The board has a static ip address, at least thats the default setting in the code).
Observations: Destination host unreachable. However when I use debug and step by step execution the board always detects a packet received. (Even when I’m not pinging it.)
Any ideas?
Regards,
Saurav
@Thomas Jespersen
I should mention that I’m not using the code here. I am using one that is provided as an example code for the baseboard. I’m wondering if you have any pointers as to why the host would be unreachable. I’m new to ethernet so any pointer would help!
Regards,
Saurav
Hello.
I have CoIDE ver. 1.7.4 and i don’t have “Exclude from build” option. Can anyone help me?
Hello. Does anyone whom http server works, can share files? I will be very thankful
Please help me…

I’ve tried to run your software with my own setup (stm32f4discovery + dp83848) But the program stays always in this while:
while (ETH_GetSoftwareResetStatus() == SET);
After a while the while construct is passed by the board is not connected to lan. I have checked the IO many times, the LAN cable is also well. Any idea why this code can’t run?
@Archie
It sounds like the RMII pins and interface of the STM32F4 have not been initialized properly.
How long are the wires between the STM32 and the PHY board?
@shresta
Hi, can you tell me, how did you solve this problem? I have the same one and I don’t know, how to solve it.
Thank you very much. Have a nice day
@sisa
Sorry for interupt you. I just know how to make it:D
@shresta
How did you fix the “collect2.exe” error?
@Starstuff
Disregard my previous comment… I found the solution.
I need to thank the author for this code, now I can get into learning how things work without deviating my attention to other things.
CooCox is a great tool too,

@Starstuff
Hi there.
Glad to know that you got it working.
CoIDE is a great tool indeed. Hopefully this will help a lot of people to get into ARM programming easier.

Hi, I debuged and measured DP83848 on OSC, but no signal on MDC pin. Please help me..
@Thomas Jespersen
Hi Thomas Jespersen,
I have modified and connected like you are. But, I can’t run this code demo on STM32F4 Discovery with DP83848 in RMII mode. Could you send me a code has runned.
Email: ngominhtrint@gmail.com
@Thomas Jespersen
Hi,
I build and downloaded into kit successfuly, but when i ping the IP addr, it can’t run.
How can I test the hardware (DP83848 ETH module)
@Ngominhtri
Have you compiled the Keil project correctly? If you don’t see any signal on the MDC pin it sounds like your project hasn’t been configured correctly.
As I did in the CooCox project (for the STM32), changing some of the initial configuration code lines for the connected PHY, you have to remember to do the same in your Keil project, to get the DP83848 module working with the microprocessor.
Regards Thomas
@Ngominhtri
So you have downloaded the CooCox project I made, which I have confirmed is working with our DP83848 module?
Please make sure that your cables are short and well connected. I found it very troublesome most of the times because I was using too long wires.
Have you measured the signals from the Phy? Do you get any activity at all.
Pinging the IP address will only work if the device (microprocessor) has actually managed to get the IP address and is able to communicate with the router.
If your PHY connections are not wrong or the communication is being interrupted you will not be able to ping the board.
Regards Thomas
Hi,
I am new to the STM32F4, I am using Atollic TruStudio for Arm Lite, I imported the project but the debug button is greyed out also when I build the project it gives me this error “Errors occurred during the build.
Errors running builder ‘CDT Builder’ on project ‘STM32F4_Ethernet’.

Please Help me.
Thank you.
@kadir4172
Hello, I have exactly the same problem as you. Have you managed to solve it?
Best Regards,
Michal
@shresta
The project is not made for Keil, no.
You should be using the free CooCox CoIDE which uses the GNU GCC compiler.
@Erik
The project is not made for Atollic TrueStudio even though it is using the GNU GCC compiler as well.
To get it work in Atollic you would have to change some of the project inclusion settings.
But I would just recommend you to use the free CooCox CoIDE!
I manage to fix most errors to build this project.
last things i have a problem with is the error multiple definition ………

@Henk
The problem with these definitions has been discussed in a previous comment and I have written a solution to it.
Please read this solution from me here: comment-55246
Kind regards Thomas
I have downloaded example uses same connections as described above i am using wave share Ethernet board same as above but there is no response i am using IP address
#define IP_ADDR0 192
#define IP_ADDR1 168
#define IP_ADDR2 0
#define IP_ADDR3 111
ie 192.168.0.111
but not pinging
I Have set PC IP address as
192.168.0.112
@aamir
Do you connect the board to a router/gateway with an IP of 192.168.0.1?
If not, you would have to change these settings as well.
Hi all,
Could you explane How the application is controlled from website? I couldnt see the code for that?
@kahyas
That is just the original ST example where you enter the IP address of the device and a webpage shows up with the ST logo and some information.
Hi, Help me! I dowload and build. Ok, led blink but not find Address Mac, Ip
I dowload and build successful but not ping address ip.
Route Gateway 192.168.1.1
#define ip : 192.168.1.145
Hello Thomas,
I tried your idea
The solution to the problem is to right click at the file ?fsdata.c? found in the ?Ethernet/source? folder in the Project list, and then select ?Exclude from Build?.
I use CooCox with STM32F4-BB Ethernet board, i read some documentation of coocox, there should be a similar function. But cannot find it.
Should this PHY of the STM32F4-BB work with this project ?
Hello Thomas,
I found it, your copy of this file was indeed in the project file.
c:/coocox/coide/workspace/stm32f4_ethernet/ethernet/source/fsdata.c
Hope to build this at last.
For the STM32F4-BB ( discovery with Ethernet Board ) use.
PHY_ADDRESS 0x00
#define RMII_MODE ( there is a 50Mhz oscillator onboard )
//#define MII_MODE
this could also be of some help.
http://rose.eu.org/2013/category/logbook/page/14
@Henk
Thank you for the advice, Henk.
This should definitely be usefull for the people trying to use our project with the Discovery+Ethernet board combination.
Dear Sir Thomas,
I am getting mac address 02:00:00:00:00:01 and ip address 192.168.15.4 in the lease status of my router but when I write the ip address in my address bar the tab keeps on loading and at the end this message “Oops! Google Chrome could not connect to 192.168.15.4
Try reloading: 192.168.15.4″appear kindly help me out as it is a part of my project.
@Muhammad Faizan
Can you please try and ping the device and see if it responds to the pings.
You could also try to insert a breakpoint in the webserver entry point in the C-code of the STM32 device, to see if the code actually recognizes your request and tries to parse it.
Hello, can you help to make Interfacing to STM32F4x7 lwIP Ethernet network interface? I do not know where to start. What should I install on eclipse? What should I download?
@Sir Thomas
I tried to ping but the dos prompt is showing “Destination host unreachable ” and once it showed “timed out” I am really confused how to solve this issue . Can the lenght of wires be cause of this issue it is about 15 cms?
@Muhammad Faizan
Hey
I’ve got the same problem. My MAC adress is 50:32:75:57:AA:0B and ip works too 192.168.0.101.
But i got no ping.
@Jo Su
So does the webserver part work for you?
web server no work.What’s the problem?
Long wires b/w stm32f4 and shield it should be abt 5cms
every thing is working fine for me but i need to do tcp communication so kindly tell me the changes that i have to make to convert this project to a tcp echo server project as provided for STM3240G-EVAL evaluation board on keil.
@Muhammad Faizan
Really? At the video they are about 20 cms…!?
@Muhammad Faizan
I’ve shorten the wires. Now it works.
@Jo Su
Glad that it works now.
And thanks a lot on the notice to remember short wires!
There was no option for “exclude from build” in my coocox version so i have deleted the file fsdata.c after that I build my project and it gets build and it looks like this
Program Size:
text data bss dec hex filename
152328 2284 34260 188872 2e1c8 STM32F4_Ethernet.elf
BUILD SUCCESSFUL
Total time: 2 seconds
which doesn’t match the above program size, So I rebuild it again then it gives me error like
:20: fatal error: fsdata.c: No such file or directory . whay that so I am not understanding please help what shud i do?
If i comment the # include fsdata.h in fs.c file then it gives me error FS_ROOT difined first time should I delete fs.c file too please help
I solved the error …..can you say me what changes that i have to make to convert this project to a tcp echo server project . Please help me
Hi Thomas!
Thanks for working adaptation with dp83848. But there is one problem with IP. When work like in Your project (#define USE_DHCP)- all works fine. But when I want to use static IP adress and comment #define USE_DHCP, at this case device does not receive IP and does not respond to pings from console. I can’t understand why?
@metcenger
Are you sure that you assign and tell the lwIP to use the static IP as well.
But actually just removing the definition of USE_DHCP should make it work with static IP as the example is taken directly from the STM32F4 Ethernet Example provided by ST, I’ve just changed the low-level Phy drivers to make it work with the DP83848.
Great Work!!! Its really helped me a lot. It works fine with http protocol. Am trying to port it to tcp protocol, but finding it quite difficult since am new to the tcp protocol. Any suggestions would be grateful.
Thanks for sharing.
It’s working now, but had some problems due long wires.
I Have updated (most) of the drivers to Ver 1.1.0 and fixed some minor issues.
Dynamic IP is now working and even more important the webpage is now loading in a blink of an eye.
http://evertdekker.com/wp/?wpdmact=process&did=My5ob3RsaW5r
It’s compiled with Coide 1.7.7. In the zip file is also Em::Blocks (ebp) project file for those who want to use this compiler.
@Ed
What a great job. Glad that you managed to get it working that well.
Would you mind uploading the project again so I can get a hold of it and confirm your changes?
Hi Thomas,
I don’t know what you mean by “upload the project again” you can download it from my website with the link given in the above post.
@Ed
Thanks.
Apparently the link didn’t seem to work yesterday, but it is working now.
Hai all,
I got the project and build successfully..Kindly anyone suggest me,how to test the project??
Thank You
@Pravinkumar
What do you mean? Have you build it and connected it to the STM32 board as well?
If so you should easily be able to just download the CoIDE project, compile and start a debugging session to program the board and test it.
Is there any known problem with using timer?
I also want to user a timer (tim2 for can message) but it never counts!?
@jo
As far as I remember and by quickly checking the code Timer 2 doesn’t seem to be in use, so you should indeed be able to use it.
Please make sure to enable both the clock for the timer periphiral and for the GPIO and CAN controller if used in conjuction?
Furthermore please make sure to use the proper timing settings and that the HCLK is set right.
Thanks for the fast answer. There i’ve got to search… but use timer 2… perhaps i added to much.
And are problems with spi(3)?
I hope it’s the last question…
Greetz
In Ethernet sample (STM32F407) der is MACRO as TCP segment size.
/* TCP Maximum segment size. */
#define TCP_MSS (2017 – 40) /* TCP_MSS = (Ethernet MTU – IP header size – TCP header size) */
Using this i am able to get the data.But i cant able to receive more than 1977(2017 – 40) in server.If i increase more than this i am not getting any data.
How can i set Ethernet Configuration parameters to receive more data in STM32F407.
Kindly anyone help me plz plz…
Has any one tried this example to use DHCP ?
Some how the lwip, doesn;t get an IP address.
@Pravinkumar
What do you mean with the server not being able to receive more data? When you refer to the server, do you mean the STM32F4 device running the webserver?
If so, what type of data are you transmitting that is larger than 1977.
This amount of bytes is meant to allow a usual HTTP package with the header and post/get parameters if any. But it doesn’t allow enough room for file transfers, if this is what you are trying to.
@Henk
We tried to get DHCP to work but LWIP seems to be struggling with the implementation as well.
To get it working you could try and update the LWIP version.
You could also try and have a look at the following code from another project of ours where we have successfully been using the DHCP feature: https://github.com/TKJElectronics/IoT_Football/blob/master/netconf.c
How can I port it to STM32F107 and cubeMx ?thanks
@Rick
First of you would have to use a different set of standard periphirals library to match the F107 device. This could be done thru the CubeMX.
Though I have only tried the CubeMX software briefly and was very disapointed due to failing generators and buggy code. So I can’t tell you how to integrate this specific Phy project into the CubeMX, but you should be able to modify the generated code to match this Phy setup.
Hi Thomas !
I have a question ! I builted successfully, but t cann’t connect to httpserver , help me ! thanks…
where can i download makefsdata.exe… help me out..
thanks in advance
@vignesh
Please read the bottom section of the post which says:
…there is a very simple way to generate your own new HTML files using the ?makefsdata.exe? file found inside the ?STM32F4x7_ETH_LwIP_V1.0.0UtilitiesThird_PartyPC_Software? folder.
Please read more about how to do so at the following page: http://www.aimagin.com/tgr/tgr12/amgf4connect/doc/HTML/index.html?webpage_configuration.htm
I tried with STM32F107VCT6, but I can’t ping the board,
I use STM32CubeMx…..
I don’t understand why…? any clues ?thanks
@Rick
This project has not been prepared for use with STM32CubeMx due to the updated libraries included in this toolset.
Hi guys,
I am currently struggling with hooking up the Phy and getting FreeRTOS +LwIP running on the STM32F4-Discovery board. So far failing miserably. As a start template I have tried converting the STM32F4Cube project called “LwIP_HTTP_Server_Socket_RTOS” (STM32Cube_FW_F4_V1.7.0ProjectsSTM324xG_EVALApplicationsLwIPLwIP_HTTP_Server_Socket_RTOS).
I am doing this with Atollic TrueSTUDIO. So far I can build the project and debug it. I am setting up a static IP but I cannot ping it, not browse the website. Does not matter if I go trhough my LAN or correct directly to laptop.
I downloaded your Coocox project Ed and migrated it to TrueSTUDIO. It now works! I can ping the device and browse the http-server. It is good to know that the PHY module and the wiring is correct. Now I just need to get this FreeRTOS+LwIP project going. Anyone who have tried?
Thanks for a good blog post!
@Mattias Norlander
Hi Mattias.
Taking the STM32F4Cube project made for the STM324xG_EVAL board is made for the DP83848 Phy chip but connected in the full MII mode, where you are only able to use the RMII mode with the breakout board and the STM32F4DISCOVERY board.
As I did to this specific project, made in CooCox CoIDE, I changed the low-level Phy hardware drivers to match the reduced MII interface, so it could be used with the DISCOVERY board.
If you are migrating the STM32F4Cube project to the DISCOVERY board you would have to do the same change in the low level driver parts.
Good luck.
Best regards
Thomas Jespersen
hi, i downloaded ur project, but it has 1 err,
I cant fix it, the err is :
colect2.exe : error :ld returned 1 exit status
please help me, tnks.
I fixed it, its really good
Hi guy’s
Just for help the people who try to make pings:
You need to add -DLWIP_ICMP=1 to your compiler flags or
#define LWIP_ICMP 1
You have to enable everything you need.
Also i doesnt try dhcp but if you have problems wity that, check the lwip configuration (if dhcp is over udp, enable it)
But…
With prototypes wires like in the video, we get really bad pings. With the webpage you doest see how bad it is..
Actually i do 140ms pings and i loose a lot of data..
The mchdrv_poll is called in polling so it’s not a lwip problem
With freertos +enc28j60 +stm32f407 i get pings around 1ms (with a delay of 1ms in the task who call mchdrv_poll) so lwip work fastly.
Maybe the problems are around the wires, i will check it when i have some time ..
I will also check the pll settings..
I come back soon
Note : i will also check the schematic of discovery board, check if the pins are not used by something else
I have made some changes to my circuit, and now i can ping at 1ms and it’s realy stable!!
1/ Put the STM32f4Discovery on a proto board, and solder the cables, with the minimal length to the PHY board ! Proto cable (15cm) are bad !!!
Consequence : Now the pings request are stable: 140ms everytimes and no packets lost ! (but ping stay too high ..)
2/ I have remove the U5 component for see if it change something, result : It doesn’t reduce the high ping. So don’t remove U5
3/ I have check the PLL settings: they are correct for the STM32F4Discovery board.
4/ Remove the DEBUG in LWIP : The debug was using USART to transmit the printf(), it’s really slow!. (i have set LWIP_DEBUG to 0 but doesn’t realy work) so I have comment everything in stdio/printf.c at the function void PrintChar(char c)
5/ Enjoy, now you can ping the board around 1ms (really stable)
Another information :
You need to set “1” in Ethernet/include/lwipopts.h at the line where is :
#define LWIP_ICMP 1
This is for enable ICMP (ping request for exemple)
If you need to set something specific check the lwipopts.h file, or if that you search is not set, check the “opt.h” file but do the modification’s in the lwipopts.h file (witch is for user settings)
@Thomas Jespersen
Hello Thomas Jespersen,
I have been working on trying to port the STM324xG_EVAL Ethernet to STM32F407 for the STM32CubeMX. I have made some progress, but I cannot get it to work. I was wondering if you had a working example.
Thanks
Hello,
Check the link please, is this ethernet board suitable to use with Discovery board as well?
Thanx

Hi TPD.
This module is the exact same module as ours (please notice that the image is mirrored).
So you should indeed be able to use this module and get the HTTP example working.

@mohammad
How do you fix it? I have the same error: [cc] collect2.exe: error: ld returned 1 exit status
when I tried to build the proyect
Sorry, now I read all the comments and I fixed it.
I have problems with the ping command because I lose a lot of packets and the time of response is really high. I read that some people have the same problems, I will try to find a solution and tell how
where I can find makefsdata.exe in the project folder
@Salmen
The ?makefsdata.exe? file is found inside the ?STM32F4x7_ETH_LwIP_V1.0.0UtilitiesThird_PartyPC_Software? folder.
Please read more about how to make your own HTML files at the following page: http://www.aimagin.com/tgr/tgr12/amgf4connect/doc/HTML/index.html?webpage_configuration.htm
do I open the project with keil uVision4,. if yes how to do that
@Salmen
No, the project is made for CooCox CoIDE.
@Andy
hi ,
same probelm occur me in coocox 1.7.8 version , but there is no option to eselect Exclude from build option
@rameshwar kakade
Yes, they have removed the “Exclude from build” option in the latest versions.
Instead you would manually have to remove the C-file from the project to remove it from the build to avoid the linker error.
Hello! I am newbie! From Kazakhstan!
my problem!
[Cc] collect2.exe: error: ld returned 1 exit status
help fix the problem.
@Vitaliy
You have to manually remove some of the webpage content C-files to avoid this linker error.
Please read some of the comments above yours as the solution has already been explained.
Hi Tomas,
I downloaded your source and I compile in Coocox. But after software run, i receive repeating message on the debug serial “no active pcbstcp_slowtmr:”
I could not understand. Does the hardware is right?
I can test the hardware in some other way?
Thank you
@Jairo
This sound like the External PHY has not been connected probably with the RMII interface, or at least that it does not seem to be able to communicate properly and regularly.
Can you please check all connections and make sure that the wires between the processor and the Phy is not too long?
hey,
i want to use http socket more than 4 or 5 sockets at the same time without http_connection_close. how can i arrange my code. ??
hi how are
thank you for your project
i have problem with this
1: i connected dp83848 to stmf4 discovery and see terminal for debug i recieved = tcp_slowtmr : no active pcbs?
2: i connectes dp83848 and my pc to a modem ( have a router) but don?t get ip and MAC of dp83848?
can you help me??
@mahdi
Hi Mahdi.
Can you confirm that you have wired and connected the Ethernet Phy module correctly?
Please notice that the cables can not be too long otherwise it will affect the connection due to induced noise between the signal wires.
The error indicates that the STM32 is not able to communicate with the Phy over the RMII interface, or at least that it does not seem to be able to communicate properly and regularly.
Hi at all,
I confirm the setting:
PHY_ADDRESS 0x00
for the STM32F4-BB ( discovery with Ethernet Board ) use.
Hi. I downloaded the coocox coide, downloaded the project but CooCox CoIDE does not open the project.
Version downloaded:
CooCox CoIDE
Version: 2.0.6
Build id: 20170117-2.0.6
S.O.:Windows7 Professional.
Other then download and unzip it, do I need to do something else to make CooCox open it?
Thx
@Lobisomem
CooCox CoIDE have been undergoing tremendous changes throughout the past 3 years why this project is no longer supported.
I am no longer using CoIDE as I mainly work with ST devices now, why I have decided to move to “System Workbench for STM32”.
@Thomas Kølbæk Jespersen
I see. So … do you have a link to download the project on System Workbench for STM32 ?
thx again
@Lobisomem
I have not converted this project to System Workbench yet. So unfortunately there is no download link for the System Workbench project.
@mohammad
hello, how did u fix it?
I cant make this thing working. I put library in the place, used pin layout from stm to PHY ,compiling, seems ok, but i can’t reach http. What’s the problem. All the leds in PHY blinking perfectly. My router doest seems to see the device
@mohammad
How did you fixed the error?
[cc] collect2.exe: error: ld returned 1 exit status
@ABVF
You have to exclude the fsdata.c from compile. You can read another comment from Thomas himself explaining this above at the initials comments.
I hope that I could help.
Congrats, Thomas!! You did a great job here!!
I’d like to tell my issues with the project here for futures developers:
*First of all, if you are getting problems to ping your PHY, please reduce your cables to 5cm. Your freq is really high and interference is something real to kill your tests (lol)
*If you’re having problems at compile, make sure that your fsdata.c is out of your project to compile. You can find this file at “Ethernet/src”.
*Try to use Static IP for initials tests so, comment the line with #define USE_DHCP in main.c file. It will be a lot easier if your make a direct connection to your computer form your device and watch what is happening with the connection with Wireshark.
Hope this could be helpful.
Regards,
Alex
@Alex
Thanks for your help and suggestions Alex. I have added your hints to the bottom of the blog-post.
Hi
I tried to use the project on the link
http://www.aimagin.com/tgr/tgr12/amgf4connect/doc/HTML/index.html?webpage_configuration.htm
using stm32f4 discovery board with keil v5.24.2.0
but after modifying it as the tutorial said it did not work.
After checking the schematics I understood that the pins of discovery board in the mentioned link is straightly connected to some pins of the dp83848 chip but we do’nt have access to them using dp83848 module.
If anyone could make this project by keil , I would appreciate if shares it with us .
thanks
Hi
I tried to open the Coocox project file but it only launches the coocox software after that nothing loads up, what might be the problem.
Thanks
@Dean
Please see the update in the blog post.
I have now repacked the project into a project for System Workbench, the IDE that both ST and I recommend currently: http://www.st.com/en/development-tools/sw4stm32.html
The migrated project, which should be identical to the other one, can be downloaded from: STM32F4DISCOVERY Ethernet-Phy – Webpage example project for System Workbench
Please note that I have only confirmed that the project compiles but not tested it on hardware.
