Here is an example project which uses HAL_SPI_TransmitReceive_DMA correctly that you can use as a guide:

Hi,

Thanks for reply.

But I am facing issue STM32H745I-Disco board. I have already tried above code which is not working for my Discovery board. I User manual also not mention related to SPI pin is connected to another purpose. Could you please check once and help me for STM32H745I-Disco board.

Thanks and Regards

The discovery board has fewer pins available. You'll need to ensure the pins you are using are free and not being used by other devices on the board.
