Hi,
I'm trying to make UART DMA to work on F4, but looks like DMA registers are unwritable?
LL functions for DMA stream does totally nothing, so I tried this and the result is 0 if I read CR register.
DMA1_Stream2->CR = 1;

Did I miss something, or why this happens? On L4 everything worked well.
Solved! Go to Solution.

Enable DMA clock in RCC.
