    Turns out disconnecting the 6Mhz clock made it work.. Not sure why yet..

    Further investigation shows that the CPU is running quite happily with an external clock input (SYSPLLCLKSEL_Val=1, flashing LED etc), just SWD doesn't work when connected.

     

    For now I'll debug with internal RC, and swap to external clock on release.
