APU2 hardware acceleration: crypto module not loading?

I always use the TinyCore usb image provided by pcengines to flash bios updates via usb/serial connection. You'll find a ready to run installer here: https://pcengines.ch/howto.htm#TinyCoreLinux ... and additional installation notes regarding linux systems.

Thanks, I'll give it a whirl: that sounds like the path of least resistance. This guide is also helpful: https://github.com/drduh/PC-Engines-APU-Router-Guide/blob/master/README.md

I ran into the same problem, with apu2c4 + OpenWrt 19.07.1, freshly reinstalled last week.

My log is a bit more detailed, and I guess that's due to some other kernel module. At last I found if I remove kmod-sp5100_tco and reboot then everything works just fine. That package is related to hardware watchdog (never used for me I think).

Going to try that myself, thanks. I remember there being some module conflicts a long time ago but didn't think it might be related.
