GPIO not working on newer OS versions

[gotling]

When remote starts it logs an error.

Error: EINVAL: invalid argument, write

It seems that newer versions of OSes refer to GPIO numbers in a different way:

Simple solution

Add a GPIO Base address configuration that is added to the GPIO pin configured.

GPIO_BASE_ADDRESS = 512
LED_PIN = 3

Pin used: 515
