Hi, I would like to verify if something is connected on the second gpio bank of my rt5350. Therefore I enabled the bank in the dts and now I'm able to see it in /sys:
root@lede:~# ls /sys/class/gpio/ export gpio7 gpiochip0 gpiochip22 modem3g_enable unexport root@lede:~# cat /sys/class/gpio/gpiochip*/base 0 22 But if I try to export one of the pin I get an error: root@lede:~# echo 23 > /sys/class/gpio/export -ash: write error: Invalid argument root@lede:~# echo 22 > /sys/class/gpio/export -ash: write error: Invalid argument Can someone help me? Thanks. Bye. _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
