The doc says ST-LINK/V2 needs a CMSIS-DAP patch. And then I searched CMSIS-DAP and found CMSIS DAP/DAPLink Emulator Simulator, whose price is just $0.5 more expensive than ST-LINK/V2.
Can it be used to unlock and flash the bootloader with the same openocd commands? If yes, it's the most friendly to non-hardware developer user, because no additional firmware flash or patch is required and the price is almost the same.
