I have default image and console output. I make build with RidgeRun SDK. Follow the instruction do the "make installbootloader". Reset the board, and no more boot message from the console (/dev/ttyUSB1) from either minicom or putty from that port. What is going on and how to flash back the boot?
To restore the board back to factory default, I suggest this tool: "DM3xx SD Boot on Leopardboard" available at www.leopardimaging.com/Download.html
