I had a run through Jon Archer's instructions  to try and get the F22 Arm Workstation image working.
The instructions basically grab the image, then replace the boot partition with RPi boot, and put the v7
modules in the correct place.
I boots (woohoo) all the way to the graphical interface, but the mouse and keyboard don't work (boohoo).
Some people have fixed this by adding a static ip address, and running rpi-update via ssh. However, this
seems like a cop out to me, as rpi-update basically copies the built kernel and modules from github,
which has already been done.
Does anyone have any ideas how to either (1) debug this or (2) fix it without using rpi-update
Things I have thought of that might be an issue:
The instructions set up the v7 modules, but there is no kernel line in config.txt - does that mean it boots the v6 kernel?
rpi-update runs a depmod after putting the modules in place - is this the missing step? If so, is there any way to
perform a depmod for an arm target on an x86-64 host?
Of course, having tried to blame the modules here, there is nothing really concrete to point in that direction.
