I have a STM32F4 Discovery board and a ST-Link/V2 programmer.
I want to use my own ST-Link (not the embedded one) for programming and debugging the board.
How should I connect the external ST-Link to the board ?
Answer
You'll need to isolate the microcontroller from the st-link portion of the board. To do this just remove the jumpers on the CN3 pins.
Then, to use your external st-link, make the following connections to the microconroller pin headers:
- SWDIO -> PA13
- SWCLK -> PA14
- GND -> GND
VAPP -> 3V/VDD
Do not connect the USB cable
Program it in SW mode.
Not sure why you'd want to do this, unless you wanted to use JTAG to program it instead. If that's the case let me know and I'll update the answer.
