I'm using stm32h753, no LWIP project. Eth Tx is not working. HAL_ETH_Transmit - keep failing with DMA transmission - I have seen few posts about that issue - I tried all the solutions I saw - none worked...
I appreciate you trying to work with ethernet without using lwip. I don't know what you want to do, but I think LWIP RTOS and socket api is the most comfortable way to work with ethernet. I'm putting the cubemx project I created with nucleo-h753zi below. I hope it helps.
