1. please move the 'git submodule update --recursive --init' first, before python3 workshop.py --board $FOMU_REV
   I didn't see it because I was chasing the failures and I didn't scroll down far enough to find it

2. the build gives me a different file:

dfu-util -D build/gateware/fomu_pvt.dfu flashed fine, but I'm not sure if'ts the right code, all it does is turn the LED off, although wishbone-tool works fine when it's running. Maybe that's normal?
However building workshop_rgb.py still flashes a build/gateware/fomu_pvt.dfu that doesn't seem to do anything.
