is your app automatically stopped?

```auto

Jan 14 17:37:26 swi-mdm9x28-wp user.info Legato: INFO | gpioService[1918]/sysfsGpio T=main | gpioSysfsUtils.c gpioSysfs_SessionOpenHandlerFunc() 1176 | Assigning GPIO 8
Jan 14 17:40:09 swi-mdm9x28-wp user.info Legato: INFO | supervisor[1078]/supervisor T=main | app.c app_Stop() 3596 | Stopping app ‘gpio’

```

You can port your application to a helloworld application and see which line makes the printing stopped.

you need to set +WIOCFG so that the GPIO can be used in yocto linux.
