unable to ping on NucleoH743ZI2 with ETH(RMII) and LwIP

[SHong.5]

Hi

I'm tying for ping test on Nucleo H743ZI2 with ETH(RMII) and LwIP.

(I'm not using other Middlewares such as FATFS/FREERTOS/LIBJPEG)

When I try ping test on cmd : ping 192.168.***.***, it work perfectly fine with STM32F4 series. However, it doesn't work on STM32H743. It seems like something is wrong with STM32H7 series on ETH or LwIP.

Could anybody help me out with this?

Thank you in advance.

We've built few Cube H7 ethernet & LwIP examples for NucleoH743ZI2, and ping does work.

The problem is likely in your code. Try to start with a Cube example verbatim and make it work. Do not change anything before the original example works.

(not to discuss here various known ETH driver issues).

Thanks Pavel

I'll try out the example code first.
