Hello, I have nucleo-board and I need to debug external MCU by stlink which installed on board. I moved off jumpers (CN4) and connect wires (CN6) to external MCU. When I flashing chip using ST-Link utility sowtware. Chip flashes as it expected but when I run or debug from system workbench (SW) I get no results. Chip stays as it was.
This is my openocd output:

What could be the reason? Dose anybody had such problem?
