So I got my 8gb flash, and resized original boards partition to be smaller than second board. So now the problem is I have flashed new board, and it will not boot up. I can mount and view both partitions correctly, and everything looks ok, but I only get "CCC" when trying to boot and viewing with FTDI cable. Any ideas?
