Dear all,

I'm enjoying OpenBSD on PC Engines hardwares called APU2:
https://www.pcengines.ch/apu2.htm

There is 3 led, which could be very usefull to deliver informations to
the endusers, but I never could control them with OpenBSD /o\

Is any way to make it work ?

On PCEngines forum I got the following answer:

>You cannot control the GPIOs on J20, because those are are driven by
a NCT5104D and wbsio(4) only supports hardware monitoring.
>The LEDs OTOH are on GPIOs of the AMD FCH. I am not a hardware guy, and
OpenBSD seems to have a lot of drivers which attach - but probably none
for those GPIOs.
>If you want to dig deeper, there is AMD documentation for the FCH and
also a linux driver called "amd-fch-gpio"

>Update: There seems to be somebody, who worked on this a while ago on
OpenBSD: https://marc.info/?l=openbsd-tech&m=155355977613046


Sacha.
