  • Wow, great!

    I'm now stuck with an st-link-v2 adapter that doesn't quite want to work

    Welcome to STM32 development!

    You probably want to make sure you define the JTAG pins:­b/master/boards/

    Otherwise when Espruino 'resets', it might set the pin state of those up to analogs (saves power) which then kills JTAG until you hard reset into the STM32 bootloader mode (so it doesn't load the firmware any more).
