No recovery option for bricked board? #36

Open mkschreder opened 8 years ago

mkschreder commented 8 years ago

I see on the schematic that Boot0 pin is connected to ground. This effectively prevents one from invoking the default serial bootloader from rom. This seems rather odd design decision.

Ok so not only did I have to cut the connection between boot0 and gnd, but also wire pin 28 (boot1) to gnd in order to start the bootloader. Then another surprise: the chip is read/write protected. Luckly it was only lowest level protection so I could disable it using stm32flash -u and -k options.

Why so much inconvenience on a board that is supposed to be open and easy to modify?
