Does GPIO2 work on linux console?

BTW, you can try this example:

3

i got it like this:

root@swi-mdm9x28-wp:# echo 2 >> /sys/class/gpio/export
sh: write error: Device or resource busy

4

maybe it is already exported:

root@swi-mdm9x28-wp:~# ls /sys/class/gpio/
export gpiochip0 gpiochip1018 gpiochip852 gpiochip948
gpio13 gpiochip1 gpiochip200 gpiochip884 gpiochip980
gpio2 gpiochip1012 gpiochip820 gpiochip916 unexport
root@swi-mdm9x28-wp:~#
root@swi-mdm9x28-wp:~# echo out > /sys/class/gpio/gpio2/direction

5

root@swi-mdm9x28-wp:/tmp# echo 2 >> /sys/class/gpio/export
sh: write error: Device or resource busy
root@swi-mdm9x28-wp:/tmp# echo out > /sys/class/gpio/gpio2/direction

can you try GPIO13

seems you used wrong legato version to compile the app

it stop like this

10

it not GPIO pin2 problem it was gpio pin4 problem
it stop while connectservice to gpio pin 4
also same problem with pin6 and 13

11

I don’t see problem:

12

I have update legato version by using mangOH(leaf shell) and I can run pin13 now but pin4 and 6 still cannot run.

i have tried with your code too but i have the same error

13

you need to set +WIOCFG first for GPIO4 and GPIO6 (reset is needed after set them):
