We are using 4 Pololu Simple motor controllers to drive the main wheels of our Rascal Robo-Ops mars rover and I, in my infinite wisdom, did not make a keyed connector for the serial interface. Of course I plugged it in backwards somewhere and connected one of the inputs to our 26 Volt supply, thus releasing the magic blue smoke from the micro controllers on 3 of them. We have already ordered replacements, but I also ordered the same STM32s that are being used in their implementation. I have already reworked one of them with the new uC and I was wondering if anyone knows if I can somehow load the Pololu Boot loader onto this board so that I can get it up and running again. I have several JTAG probes that will work with the STM32, or if there is a serial boot loader factory installed in the STM that I can program through as well.
I have not had the opportunity to debug the rest of the hardware but I figure since the only thing connected to the driver at the time of the burnout was the serial connector, that the micro controller is the one thing that got fried.

Thanks ahead of time for any help
