Is there a way to control these in software from OpenBSD? 2) There are 16 additional GPIO on a header, via the Nuvoton NCT5104D chip on the LPC bus. I've seen a few patches circulating that mentions gpio and the wbsio(4) driver but I could not figure out if anything has been committed or not. 3) There is a simple watchdog timer in the NCT5104D that can be connected to the reset line. Would this be implemented? I'm not sure it's really useful, I assume there's an integrated watchdog in the CPU. Would be interested in hearing from any OpenBSD APUx user who put these to good use! // Anders >
