How to modify a cheap ST-LINK V2 clone to enable the SWO pin for ITM printf debugging in STM32CubeIDE.
In this video I will explain hot to enable the SWO pin so that to use the ITM functions and SWV functions offered by the STM32Boards. I dont take any responsibility if you happen to break your debugging tool while doing this mod. Two useful links if you want to understand better how to mod the Debugger clone so to enable the SWO: - research.kudelskisecurity.com/2020/04/15/swd-part-3-swo-and-… - eeblog.co.uk/2018/11/29/swo-with-cubemx-using-st-link-clones…Why it's here
