Hi @Bilge​ ,

I think this is missing before the main loop:

 /* Http webserver Init */

 udp_echoserver_init();

Did you get it working?

Jack.

Hi @Jack​  ,

I can ping to my board without packet losses. My current goal is to send and receive packets with udp protocol.

Hi dear Imen,

I'm using STM32Cube_FW_H7_V1.4.0 and still I'm not able to ping my board.

I've disabled DHCP, and I'm not using RTOS.

Most of the settings were left at their defaults. However, to enable the webserver, the following

options were enabled: LWIP_HTTPD, LWIP_HTTPD_CGI and LWIP_HTTPD_SSI. Because the Nucleo

board has bucket loads of memory, the maximum tag length (LWIP_HTTPD_MAX_TAG_NAME_LEN)

was increased from 8 to 16 characters.

May I ask you to help me by providing step by step instruction?

I've attached my project.

Please let me know how can I solve my problem.

Thank you in advance.

Hi @Bilge​ ,

Community members are not able to create new topics ( topic = tag). Only ST employees and moderators can do that.

If you want to add/edit your Topic, you should use the existing one.

Best Regards,

My fixes and improvements to ST's STM32H7 ETH driver and lwIP ethernetif.c are at https://community.st.com/s/question/0D50X0000C6eNNSSQ2/bug-fixes-stm32h7-ethernet.

Source code and documentation attached.

I don't use evaluation boards or build example code.

You'll have to port my changes yourself.
