Hi,
I wanted to use pins 4, 6, 8, 10, 18, 19 and 20 as GPIOs, so I commented the following lines in armstonea9r2q.dts:
Now I have those pins working fine as GPIOs, but I have lost the serial debug port (pins 53..61). I wonder if this issue is related in some way with the lines I commented or it has nothing to do with it.
Thanks in advance!
