Should be fixed now in the current tc2 branch Ok, I'm not very familiar with git & co. So far I do not see a change/update on the 'web frontend' of your repo. (https://github.com/tomtor/freebsd/tree/c2) Do they (github) update only after a 'certain period'? > > I have attached an USB disk and an USB ethernet adapter and the system > > boots, NTP adjusts the date and I'm logged in with SSH. > > > > However, a "portsnap fetch" runs a long time and then exits with: > > pid 78242 (sh), uid 0: exited on signal 10 (core dumped), so it is > > obviously not ready for general use. > > > > Boot instructions are here: > > > > https://github.com/tomtor/image-freebsd-c2 > > The boot process stops and complains filesystems not known.

This was with -CURRENT and your changes from the c2 tree. So it seems that something changed between -CURRENT and your tree which stops booting. That is why I took a snapshot from your tree to find out what the difference is. > I do not have much time the next few weeks, but I will try to get the > SD-card and board ethernet running later or perhaps someone else will > have a go at it. > > Note that the occasional core dump is very rare.

The Odroid-C2 is really a nice > little device. I'm interested in a running C2 to continue gcc stuff I started with qemu. I need horsepower and I expect the c2 will fit my needs. Thank you for starting this port. Andreas
