Target disconnected error

[ItzNicolo]

Hi.

I have recently encountered a problem that I'm not capable of solving in for a few hours now.

I'm using STM32F042K6T6 as a uC and, when I try to debug my projet, it shows me the following errors:

Failed to execute MI command:
target remote localhost:2331

Error message from debugger back end:
Remote communication error. Target disconnected.: No error.
Failed to execute MI command:
target remote localhost:2331

I'm trying to fix those problems for a few hours, but with no succes.

Can someone help me solve me this?

Also I'm using J-LINK as a debugger.

Best regards

Hello @ItzNicolo and welcome to the community,

Could you, please, provide the debug configuration and the GDB server log? This will help us to analyze the problem further. Also, check that the J-Link is correctly connected to the board. This knowledge base link may help.

Thanks,

Rim

What ended up being the solution for this error message?

I don't know. I just restarted the app and the error message disappeared.
