hi, I need to stop some peripherals within m4 core before linux stop command:echo -n stop > /sys/class/remoteproc/remoteproc0/statehow can I manage that ?tnx.
Hi, I'm porting ADC on M4, but some how the converting result is odd value always, seems the DR bit-0 is always '1'. I tested it by VR, range from 0v to 3.3v, the ADC suppose to convert it from 0 to 255, but I don't know why, I just get odd value bac...
