Please add support for ASRock IMB-1313 motherboard

[is-eouellette]

Hi, On our ASRock IMB-1313 industrial motherboard, we're using GPIO70-GPIO72: (Please see attached user's manual, p. 24) GPIO70: push button switch input: N.O. (L), pushed (H) GPIO71: buffered Green LED output: L (off), H (on) GPIO72: buffered Amber LED output: L (off), H (on)

We're running Ubuntu 22.04 OS (tried desktop and server versions)

For gpiod, we compiled v2.2 from source code here: https://github.com/brgl/libgpiod/tree/master

Then tried command line tools like:

sudo /usr/local/bin/gpioset --interactive -c 0 71=inactive 72=inactive gpioset> set 71=active gpioset> set 71=inactive gpioset> set 71=active gpioset> get 71 "71"=active

But I observed no changes to the LED. Would you please help us with GPIO support for this Intel motherboard? Thanks! IMB-1313 User Manual.pdf IMB-1313.pdf

I'm afraid you may be confused as to what libgpiod actually is. There's no support for any specific piece of HW in the library. That happens in the linux kernel which - through a well-known interface - exports the GPIO functionality to user-space. This project just wraps that kernel interface and aims at making it easier to use. You need to find out why the kernel doesn't toggle your GPIOs.
