Yes, I did forget to ask what firmware version you're using (silly me). Latest version is 0.97. Binary firmware images available here: https://firmware.intel.com/projects/minnowboard-max

[Update] maybe if you can get a copy of the current firmware and the version just prior to that you could start by flashing the prior version just to test. if that version works you could keep it or try flashing the latest to see if anything changes with that version.

It runs the memory check then goes to the UEFI shell (which shows no devices).

And (lo and > behold!) if I hit the F2 key while it is rebooting the keyboard is live and I get dropped into the BIOS boot menu. I can then use the keyboard to choose to boot from either the Ubuntu SD card or a USB stick with the Ubuntu installer, or anything else I might wish.

But unplugging the power causes that initialization state to be reset and the keyboard goes inactive until the next time it boots into Ubuntu. > It’s starting to sound like a firmware bug… If so, I’ll be happy to > work with the engineers to debug it and test a fixed firmware version. > Enjoy! > Rick > _______________________________________________ > elinux-MinnowBoard mailing list > elinux-MinnowBoard@lists.elinux.org > http://lists.elinux.org/mailman/listinfo/elinux-minnowboard _______________________________________________ elinux-MinnowBoard mailing list elinux-MinnowBoard@lists.elinux.org http://lists.elinux.org/mailman/listinfo/elinux-minnowboard _______________________________________________ elinux-MinnowBoard mailing list elinux-MinnowBoard@lists.elinux.org http://lists.elinux.org/mailman/listinfo/elinux-minnowboard
