every time I configure the IO pins on my Banana PI M1, according to the example below who php:
<?php
exec('echo "4" > /sys/class/gpio/export');
exec('echo "in" > /sys/class/gpio/gpio4/direction');
exec('echo "7" > /sys/class/gpio/export');
exec('echo "in" > /sys/class/gpio/gpio7/direction');
I already did it in script, python and in C....
and always the same error, my network card stops working, the rest of the hardware works normally, I put a monitor on the hdmi output and the rest of the hardware is normal, only the network card stops working, what to do?
how can I solve? does anyone have any tips?
