Hello @No_Name and welcome to the community;

 

Are you able to connect properly to your device using STM32CubeProgrammer?

Try to ensure an STLink firmware upgrade first.

Do you still have same issue?

Thank you.

yes if in STM32CubeProgrammer it can, but I want to see the debug output of the STM32 device, I use ST-Link V2 mini, and the target is STM32 bluepill STM32F103C8T6.

I am using STLink V2 will buying STLink V3 solve the problem?

[Andrew Neil]

That depends on what the problem is!
