[Mahmoud Ben Romdhane · Accepted solution]

Hello @snowuyl ,

First let me thank you for posting and welcome to the ST Community.

I reproduced your request using STM32CubeMX 6.15 and I did not get the compilation errors.

I suggest that you download STM32CubeMX 6.15 through this link:

STM32CubeMX - STM32Cube initialization code generator - STMicroelectronics 

Thanks.

Mahmoud

FWIW, All of those seem to relate to things defined in both ethernetif.c and eth.c
