where does it fail?

I have seen lots of reports in this forum asking why the DMA does not work.

So far I have only seen implementations, where the DMA HAL drivers were completely disabled in the BSP settings, and the DMA registers is programmed directly.

I also find it much more understandable than the HAL drivers.

Yes, i experienced it too. but I dont have much tutorial on DMA registers. So i have no idea where to start and how to do it.
