how to properly define STM32H747i-Disco for ping test?

Hello!

I am working with the STM32H747i-Disco board, my aim is to create ethernet connectivity between the board and the PC, as a first step to send a ping from the PC to the STM32H747i-Disco and get a response. My cubeMX version is 6.2.1, the H7 firmware repository is version 1.9.0.

first, i have made the nessecery HW modifications to the STM32H747i-Disco board in order to connect the proper ethernet pins to the MCU. (SB8 closed, SB21 open, R87 open, SB17 closed).

i have defined a cubemx project according to the instructions in this link: https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working . with two exclusions:

  1. The ethernet is defined in RMII mode (since MII isnt possible on the STM32H747i-Disco).
  2. Clock source is HSI (and not HSE) - but still with 400 MHz for the M7 cortex (the ethernet is connected to the M7). I Also tried defining teh HSE option, it didnt change the outcome.

i configured the PC ethernet connection to a static IP (192.168.0.7) , also, disabled the DHCP on the board and gave an IP address as instructed (192.168.0.10).

after the code generation and running the project code on the board i connected the PC and board with an ethernet cable, while debugging i saw that the link functions are activated as expected.

unfortunetly, when i try to ping the board from PC i get "Destination host unreachable".

what might be the reason? why cant i get a ping response?

please advise on how to perform this test succesfully and correctly.

thanks in advance.

    Hi All!

    The issue was resolved, it appears that i have configured the MPU incorrectly.

    Now i have verified that these (https://community.st.com/s/article/How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working) config instructions with the STM32H747i-Disco.
