Hi there ,
I was trying to export GPIO pins 35,36,37 (using WP7502) with a terminal command
=> echo 35 > /sys/class/gpio/export but this gives me the following error
==> sh: write error: Operation not permitted
i referred one of the query in the forum where in i found AT+WIOCFG? (AT command using which i found that app processor has access to the GPIO 35,36,37 )
and on the other end exporting GPIO 25 doesn’t give any error .
It could be good if somebody gives me pointers to overcome this issue .
