System Workbench for STM32


ST Link v2 Not detecting target

So I made a custom STM32F446RET6 board and I first used a mini ST_LINK programmer to connect to the MCU. I was able to program it but couldn’t debug it since the mini ST_LINK programmer lacked the SWO pin. I used ST32 ST-LINK Utility and Keil to program the chip.

I then purchased the ST_LINK V2 programmer from ST but it doesn’t connect to the MCU (target). My laptop does recognise the ST_LINK V2 programmer since I have the stsw-LINK009 software installed. The SWCLK. SWDIO, and SWO pins are directly connected to the male headers as seen in the picture.

I also attached the trace.log file from STM32 Utility

Any ideas as to why this is happening?
