Forum: System Workbench for STM32

Posted by PasKol on 2017-12-26 19:40

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.

Here is the trace.log file from STM32 Utility (size is too large to attach the post):

Any ideas as to why this is happening?
