I have Starterkit PicoCOMA9X Linux with pre installed Linux fsimx6sx 4.1.15. I want to toggle the PIn 3 of J10 connector (IO8) which mapped to gpio43 according to PicoCOMA9X GPIO Reference Card V1.0.
I do the following steps which are mentioned in "F&S i.MX6-SoloX Linux First Step" document for setting the pin:
- echo 43 > /sys/class/gpio/Export
- echo out > /sys/class/gpio/gpio43/direction
- echo 1 > /sys/class/gpio/gpio43/value
All of commands are working without any error, apparently, the direction will Change but value can not be changed to 1. I have run the command "mount -o remount, rw /" also the permission for file value is "-rw-r--r--". Is there something missing? or is there any other way for toggling the gpio?
