After you've resolved your PHY problem, check out my bug-fixes and improvements to ST's STM32H7 ETH driver and lwIP ethernetif.c at https://community.st.com/s/question/0D50X0000C6eNNSSQ2/bug-fixes-stm32h7-ethernet.

Hi Alister

Thanks for your answer.

I read the link, I find that v1.5.0 & v1.6.0 has the problem .

I use v1.7.0, this version still has the problem

Just replace the file is ok ?

Read the posts there carefully. Porting it to your software is technical and requires skill and care. If you use it, to assist other developers, please post a summary there confirming it's ok and/or any problems with it you'd had to solve. Thanks.

Hi WTieg.1

Have you succeeded in modifying the code to interface with the DP83822?

To Hvict

I solved the problem

But I don't know how to submit my bug-fixes and improvements

Add "Bug-report" to your topic list, attach the fix, CC @Amel NASRI, and search community for any updated "how-to" instructions.

Hi @WTieg.1
