Hello ST Community,
I am currently working with the Nucleo H723ZG board and facing issues establishing a ping response using the LWIP stack. Despite following various examples and configurations, I have been unable to get it to respond to pings. Here are the details of my setup:
- Development Environment: STM32CubeIDE V1.17 and STM32CubeMX V6.13.0
- Configuration:
- I have not used RTOS.
- I configured the Ethernet settings according to package examples.
- :C:\....\STM32Cube\Repository\STM32Cube_FW_H7_V1.12.1\Projects\NUCLEO-H723ZG\Applications\LwIP\LwIP_UDP_Echo_Server
- I ensured that the Ethernet cable was connected properly and used a direct connection to my pc.
I have tried multiple versions of the H7 package ( 1.12.1 - 1.12.0 - 1.11.1 - 1.11.0 - 1.10.0 ) and tested various configurations without success. The ping command consistently results in "destination host unreachable."Could anyone provide insights or suggestions on what might be missing or misconfigured?

/* Remove information from the standard libraries */

and its result is like this:
My main.c code:
//**********************************************************

extern struct netif gnetif;

ethernetif_input(&gnetif);
sys_check_timeouts();
}

ressult:
My CPU clock is 520Mhz. I am sure the hardware has no problem because I can give a ping from the st package example.
But when I configure according that example it does not work.
.Thank you for your assistance!Best regards,

A few weeks ago, I encountered a significant hurdle while implementing Ethernet functionality on an STM32 microcontroller. The complexity of the task led me to seek assistance in formulating a comprehensive questionnaire to better understand and address the issues at hand.After thorough research, experimentation, and persistence, I'm pleased to announce that I've successfully resolved the problem and implemented a working Ethernet solution. This breakthrough marks a significant milestone in my project and enhances the capabilities of the STM32 microcontroller I'm working with.Below, I'll share the details of the solution I developed, hoping it might benefit others facing similar challenges in their embedded systems projects:

I added this to while(1)
MX_LWIP_Process();
