I write code rather than tutorials. You need to watch the memory used, the alignment, and cache coherency.

I wrote code, below i am attaching code and screenshot of ioc settings in which DMA is not mentioned, and also attached schematic of stm32h7vbt6. I think the connection of vbt6 board is not correct.

First I simply try for create the file. kindly go through below attached file.
