PC Engine APU1 - GPIO and LEDs

Erik Lax-2
Hi,

We're looking into getting GPIO and LEDs working on the "new" PC Engine
APU1. We found FreeBSD drivers[1] and Linux drivers[2], documentation is
indicating it's driven by the AMD A50M FCH south bridge chipset[3]. If
anyone would be interested in hacking on this, we're able to provide
complementary hardware and/or monetary sponsoring.

If not, approximately how extensive would such implementation be in
terms of LoC/new code to be written?

We have an implementation which needs to be cleaned up if you want...

Hi,

I could try to clean it up. I have nearly no experience in writing
drivers, but i like to learn more
about that and thats why im asking if you could maybe send me the diff.

I have a PC Engines APU myself and would love to have it fully functional. :)
