Dear Andrew,
I'm in Cristoforo Abbattista staff.
We have redboot running on DEBUG port (dev/ser0).
What do you mean when you say "putting a break point in the ISR/DSR"?
We have 2 serial port, one for gdb or minicom and the other connected to the cam. The
problems are on the ones connected to the cam. It seems the V850 sends bytes
correctely but doesn't send some signals necessary to wake up the cam from the sleep
state.
It is clear now?
Teresa
