I have tried out it8712f_gpio31_raise patch, but it did not worked. I
have measured the #TBL pin voltage, and it was pulled to GND during my
As a brute force attempt I have added a loop to go through the GPIOs
from 1 to 63 during the board enable, but as I have seen there are
multiple checks to prevent doing something silly with those pins. This
attempt was neither lead to success.
I had to give the board back to the owner, but I might have access to it
in the future.
Lately I had an idea that I will use a DMM (digital multi meter) in
