The bug was in the param-sets of the edma which were not set correctly in my application.

Thanks for that, but how do you do the same thing with a systemd service? My filesystem is using systemd for startup. Steven Hill

In your script that runs the app, just "cd" to the correct directory. I.e.
cd /mnt/user_nand
./myApp mydspE...

Was the bug in the kernel or your application? Jonathan Cormier
02:09 PM Software Development: RE: EDMA conflict DSP <-> Linux
Found the reason. The DMA configuration was wrong. Benedikt K.
