I'll try the build in the morning on my C1+, btw the I just read on the git page for this build that you cant use serial because of the "special" socket, I just use a standard PL2303 with the 4 wires and jam them on the pins (minus red) lol, works fine, the pin outs are listed on the hardkernel site.
BTW I too also have a C2 board.
