STM32H743VIT6 can't connect with a LAN8720!

[DK.7]

I have WeAct STM32H743 (STM32H743VIT6 ) and I can't connect it with a LAN8720 module!

I did all my steps according by example from this link https://www.st.com/en/embedded-software/stm32cubeh7.html

But, it doesn't help me!

How to find out at what stage I have break a code?

Thanks for the answer!

Unfortunately I only have the ability to connect only RMII mode. Do you have the same detailed instruction but for RMII Mode?

Hello, No idea from your writing what happen nor issue type to try help you.

At first are you using a custom board? How did you connected PHY 8720 to board?

Is some way software running or terminate with hard fault?

8720 is an RMII only device like the 8742, this need change PHY driver. Browse forum, you can find driver and instruction to patch software.
