Another thing you could try would be to use the script in
tools/readserial.py on the host machine that reads from the serial
port of your target machine.  That script can provide timestamps on
debug messages which may help correlate the frame count time (236ms)
to debugging messages at that time.  Use the "-n" option on the script
- something like:

./tools/readserial.py -n /dev/ttyUSB0 115200
