We are bringing up a new board and having troubles establishing SWD connection, I was reaching out seeking help with this.
- Target - STM32F091RC
- ICSP - ST-Link/V2
- IDE - TrueSTUDIO
This is our first use of the ST-Link outside of Nucleo-64 board development and I was thinking it may be best to start there:
- Board - NUCLEO-F091RC
When I hook the Nucleo-F091RC up to the external ST-Link/V2, I use the following wiring & apply 3.3V -
Config:
- CN2 - Jumpers Removed
- Vdd - 3.3V (CN6.4)
Board Wiring:
- Vdd - CN6.2
- Gnd - CN6.6
- SWDIO - CN7.13 (PA13)
- SWCLK - CN7.15 (PA14)
- SWO - CN10.31 (PB3)
- NRST - CN7.14
ICSP Wiring:
- Vdd - p1
- Gnd - p4
- SWDIO - p7
- SWCLK - p9
- SWO - p13
- NRST - p15
When I launch an existing project that works using the onboard ST-Link it now reports "a problem occurred", see attached. What is the issue here?

St-link part(left Nucleo) rest of Nucleo (right Nucleo) signal
CN4 pin 2 CN7 pin 15 SWCLK
CN4 pin 3 CN7 pin 19 GND
CN4 pin 4 CN7 pin 13 SWDIO
CN4 pin 5 CN7 pin 14 NRST
JP1 left pin CN7 pin 12 +3V3_ST_LINKProgramming and testing programs run entirely properly in this combination. Of course, CPU power supply can be solved in another way. Here is powered from 3.3V St-link, because it is so easy for me. For this test, in the right Nucleo it is open jumper CN12 (because not powered St-link bother NRST line), but in your situation it does not matter.
