SWD header CN5
The 6-pin SWD header is used to program or debug an MCU in an external application
board using a dedicated cable connected to it. To use this SWD header interface, pins 2 and
3 of JP10 need to be connected with a jumper. Furthermore, SW1 must be set in OFF
position while R24 and R31 need to be disconnected.
By default, STLINK/V2-1 is used to program or debug on board MCU. Pin1 and 2 of JP10
are connected, SW1 is in ON position, R24 and R31 are connected.
