Nucleo ST Link to Maple Mini connections

This great short guide was posted by Madias in the forum: (Quick and dirty) upload Bootloader on a maple mini with any nucleo board (via ST-Link 2.1) Disconnect both CN2 jumper (left bottom) on nucleo SWD connector: Pin1: VCC (not working for me? Take any VCC pin and connect it to "Vin" on the mini) Pin2: SWCLK -> D21 on mini PIn3: GND -> GND Pin4: SWDIO -> D22 on mini Pin5: NRST -> RST on mini Pin6: SWO (nothing connected) Get your maple mini into the serial bootloader mode: Hold both buttons (reset + button) and then release the "reset" button (maybe not needed if maple isn't freezed) now drag&drop any *.bin file (bootloader) in your finder/explorer to upload it.
