Hello,
I am using DMAMUX(dm) chaining, that means there are n dm channels and the previous is generating an event for the next dm channel as a sync input. I noticed that there is a latency in the transition of one dm channel to the next one. For example if dm channel 0 is done(event is generated to dm channel 1), dm channel 1 starts with a latency of around 200ns.
The latency is independent of:
- nbreq
- dma trigger source frequency
Did sombody else notice that aswell?
