Hi Andy, I've dusted off the Edison and have confirmed that it starts up:

Hit any key to stop autoboot: 0 => Now I can see the instructions in doc/board/intel/edison.rst but I am not sure how to translate that into a lab. Basically I have: - UART - Relay hooked up to the RESET button (SW1 U15) - power control The instructions in edison.rst are quite complex. I can run the xfstk-dldr-solo tool but I don't want to have to download and install a recovery image even time I want to try a new U-Boot Basically what I want is to be able to send U-Boot to the board over USB and then have it boot into that U-Boot. It seems that once U-Boot is installed the board behaves differently, but there must be a way around that. Any help much appreciated. It was nice to meet you in person! Thanks, Simon
