Hello,

i would Transfer Memory to Peripherie (SPI: IN[x] Register).

I select as follows:

- Trigger Type = SW Trigger
- Transfer Flow type = Memory-Peripherie (1)

Start the Transfer with DMA002_StartTransfer();

But it don't works!

Now, i change manual - Transfer Flow type to 0 and now it Works!

Why?

nice greetings
