Difficulties pinging the STM32H7 which uses LwIP and FreeRTOS. STM32H7 can send the UDP packet to the server but the server cannot send UDP packet to the STM32H7. I cannot ping the STM32H7, what could be the cause here?

Hello everyone,

I'm trying to set up the LwIP and FreeRTOS on the STM32H7.

Currently I can send UDP packet from the client (STM32H7) to the server (PC),

but I cannot ping the STM32H7.

There is the main.c in the attachment and the lwipopts, ethernetif and FreeRTOSConfig.

Here is the image taken from the wireshark. The STM32H7 was given the 192.168.0.100 and the server 192.168.0.238 address.

 

What could be the issue here?

Is it the initialization or the configuration files?

I'm running out of ideas and any help would be greatly appreciated.

Thanks
