IoT card GPIO access


I am using mangoH red

I can access the IoT GPIO pins using the Legato framework.

I would also like to know how can I access it via standard Linux interface, of course using export, direction etc, but I need to know to which gpiochip are the expention pins related.

thank you

This issue is discussed somewhat here: Activate gpio expander

There is a team responsible for the reference Linux system within Sierra Wireless and I have been pushing them to address this issue.
