Not enough to go off of here. "I'm trying something but it doesn't work" is hardly an actionable question.

Add more details including what you've tried and relevant parts of code in the question comments.

Did you check DMA memory address in the link file? Is it set to 0x24000000 ? See the DMA does not work on STM32H745 thread
