No ST-link detected! Please connect ST-LINK and restart debug session.

[CLled.1]

Good morning everyone,

I'm using NUCLEO-WL55jc1 board and STM32CubeIDE 1.10.1. The case is that before creating a new second project, the ST-LINK V3 was detected and everything worked properly. However, currenly, when I want to debug the program I get this message (even with the first project I have, LoRaWAN_End_Node example).

I hope someone could help me.

Thank you very much,

Carlos

In addition, I should mention that the LoRaWAN_End_Node example is still running as I could see on Tera Term.

Hello @CLled.1

I reproduce your issue at the beginning i see the same error message "No ST-link detected! Please connect ST-LINK and restart debug session"

I simply change the cable port and then everything is working fine:smiling_face_with_smiling_eyes:

So try to do the same thing and tell me what's up !

Thanks,
