On H743ZI which is very similar it works without any problem for me, but not the CubeMX version. A freshly generated CubeMX version immendiately gives ethernet DMA error and everything stops, so tried an example located in Cube repository ( STM32Cube_FW_H7_V1.4.0\Projects\NUCLEO-H743ZI\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS ) and it works, I compiled it with Atollic TrueStudio.

I appreciate that! I have run through forums and forums and failed. I am tired with ST now. I wish ST would help us here. Else i have ditching this board

Don't ditch the board, try the example what I provided, and not the cube one. Post the result after you tried it. I'm also sometimes angry for ST, but ST has still pretty good support for things beside other manufacturers.. Now I'm struggling for days with nRF52 and I'm unable to use a simple beacon example which is made by the company because It doesn't want to run. It much worse than ST. (I already once whet out an MCU from an F7 board because it doesn't want to program the flash memory :grinning_face_with_sweat: )

Refer https://community.st.com/s/question/0D50X0000C6eNNSSQ2/bug-fixes-stm32h7-ethernet. You'd have to port it to the board yourself. If you use it, please post there confirming it works for you and on what, or any questions.

I tried the example project on my board and it worked 2 times. After disconnected the board from power supply it's not possible to connect anything to it. The controller is not responding. To solve this I have to pull up the Boot0 pin and do a full chip erase.

When I only use the M7 core there should be no problem, right?
