Using an external debug tool to program and debug the on-board STM32

To support an external debug tool, set the jumper (JP1) to isolate the output I/O from STLINK-V3EC. Then

connect the external debug tool through the STDC14/MIPI10 debug connector (CN4).

When using the external debug connector (CN4), it is possible to use the STLINK-V3EC USB connector (CN1) to

supply the Nucleo-64 board or select another power supply source as described in

power

selection.
