Actually, I rather spoke too soon. Rebooting succeeded, but a later cold boot failed: the device didn't start flashing its activity LEDs and wasn't reachable over the network. Maybe there are some things that don't work in the upstream kernel that don't affect a reboot, or maybe systemd does some "helpful" things to simulate a reboot that I didn't know about. (It's always worthwhile to speculate about systemd and other "opinionated" software doing "helpful" stuff.) > You could also try the latest > > http://git.goldelico.com/?p=letux-kernel.git;a=shortlog;h=refs/heads/letux-5 > .1.8 > > with letux_defconfig. > > The main differences are > * adds your JZ4730 code (but does not make use it, obviously) > * some diffs in the defconfig > * prepared to build pvrsrv.ko > > > I was able to ssh into the CI20 and find it over the network again! > > Yes, Ethernet and ssh seems to work. I do actually wonder if there isn't some very basic initialisation that does not work. Maybe it is related to the flash memory issues described on the ci20(-dev) mailing lists. So perhaps I will start the kernel with the UART cable attached and see what is reported.

I also looked at Mathieu's separate linux-ci20 repository, but the tip of that didn't manage to build, complaining about rules to make various clock-related files.
