I have been using the following setup for trying out a few demo programs. I use the jLINK OB. However it appears that I have blocked my STM32 by uploading bad code.

Is there some means of resetting the board in the current setup, to be able to reprogram / debug it.

    You'd want to find the BOOT0 pin, and have it pulled high at RESET. This would run the System Loader code instead of whatever broken code you have loaded currently.

    Try to avoid reprogramming the GPIO pins related to th JTAG/SWD interface, or low power WFI loops.
