NUCLEO-H743ZI LWIP using STM32cubeMX?

Hi, 

 I generated a simple LWIP/UDP project for the NUCLEO-H743ZI using the STM32cubeMX. But the function HAL_ETH_Transmit(&heth, &TxConfig, 0); returns with DMA error . 

 My board works using the example from the STM32Cube_FW_H7_V1.1.0. So the hardware is ok. 

 What is wrong with my configuration?

Jeanne,

My problem was that the STM32CubeMx generates a LwIP project using the DTCM RAM (0x20000000). I had to modify the linker file to point to the AXI SRAM (0x24000000) instead.

There's a way to modify the memory region in the STM32CubeMx project configuration? I think that the default should be AXI SRAM for the H7.

I agree you with the suggestion to set the default memory region to AXI SRAM on H7 or to make it as configuration in CubeMX. I've searched many hours to find the issue for my SPI+DMA problem.
