| The MCU module has a USB port, but direct programming would only be possible with a USB-UART programmer. It would also require a different bootloader protocol. Instead, we make use of SWD functionality. The MCU module has a typical JTAG/SWD header and these pins are also available on the two 2*25 header rows. | The MCU module has a USB port, but direct programming would only be possible with a USB-UART programmer.

| + | I believe that the BOOT CONFIG switch should be set to SYSTEM, although I think this is more relevant for flashing through UART rather than SWD. | ||

| - | Note that pin 1 of the 6-pin SWD interface on CN2 of the Discovery board only **detects** the voltage of the target. Thus the most foolproof method of flashing is to connect a mini USB cable and set the power switch to USB. This ensures that 407v board is always powered up when programming. After the bootloader is burned in, the 407v board can be installed in the wCore PCB through the two 2*25 headers. | + | Note that pin 1 of the 6-pin SWD interface on CN2 of the Discovery board only **detects** the voltage of the target.
