Error

->Failed to set Direction on GPIO gpio22
->Failed to write out to GPIO config /sys/class/gpio/gpio22/direction. Error Operation not permitted

i need solution for this one.

Hi,
May I know on which module you are checking. please provide the log of cm info, fwupdate query and commands tried for setting directions.

module wp7608
Legato Version : 18.05,1

Hi,

We have verified with legato-18.05.1 on top of Release 9, Also with Release 10.1(legato-18.06.3) and Release 9(legato-18.03.0) using WP7607 we are able to set the direction succesfully without any issues. Below are commands which we tried,
echo 22 > /sys/class/gpio/export
echo up > /sys/class/gpio/gpio22/pull
echo in > /sys/class/gpio/gpio22/direction

On top of which Release version you are using legato-18.05.1?

Below are the logs for your reference:
