That's good news. So blue LED is flashing means the firmware if alive. Please erase chip/program again just to be sure you are running full defaults, if everything else is fine microUSB is supposed to be alive.

Your other option is to try USB/TTL port (PC10/PC11) since that's independent hardware.

(not exactly repair - more like modification)



That's an old spreadsheet - I was trying all discovery pins to make sure they would blink an external LED. The red pins are the ones which did not blink for some reason.

PD0
PA15
PC8
PA9

Anyone has time to check what these are used for on discovery and if whatever would be removed from the board easily to make these pins usable for us?
