Hi,

This is just the info/error : DMA impossible, because you didnt activate any peripherals to work with the DMA.

ie:

Select anything you want to work with DMA : SPI , ADC, I2S ... , set it to the mode you want, then you can add a DMA channel there.

ADC example:

I understand, however I would like to set up DMA for memory-to-memory mode, not from peripheral to memory or vice versa.
