Buster DMA changes - now uses DMA4?

Tue Aug 20, 2019 12:10 pm

I'm getting errors on a program that worked under Stretch and Jessie using DMA 4. I assume this is now being used by Buster but the original method for interrogating which DMA channel are in use also no longer works

cat /sys/module/dma/parameters/dmachans

How do I do this on Buster and is there a list of DMA channel usage anywhere?
