Hi Robert, Installing was no problem, however I have trouble connecting to the board via SSH. After a power down, Cloud9 works, connecting via the debug connector works up to a point.. When connected via cloud9 I can create new terminals, but finding out about the network (ip addr) for example hangs the (remote/debug) terminal. I've got a gist here with the serial debug output during startup: https://gist.github.com/luminize/9c747b83bbda4c589a0b516edb122b96 dmesg further periodically shows this: [ 242.872671] INFO: task systemd-udevd:494 blocked for more than 120 seconds.
