Can't use HW reset mode to connect to Disco board using external ST-LINK v2
Hi,
I don’t think it is a good idea to let the F4 disco powered and try to connect with an ext STLink on the F4.
Maybe the reset line is still connected as you said.
You should be able to debug your custom board with the ext STlink V2.
On the 20 pins header of stlink V2, you must connect:
- The 2 SWD lines (7 for SWDIO and 9 for SWDCLK)
- GND lines (at least one of pin 8, 10, 14, 18 or 20 or all of them)
- VDD appli of your custom board on pin 1
- STlink RST on pin 15
Rgds,
