SERVER CONSOLE DEBUG: GDBServerConsole: onBackendConnect: gdb-server program client error Error: read ECONNRESET

[Emile]

Hi!

I'm developing a project on visual studio with ncs sdk V1.8.0. For a while, I was able to debug my project with no problem. But out of the blue, I'm no longer able to debug my project. I get the following error:

[2022-08-23T15:57:09.597Z] SERVER CONSOLE DEBUG: GDBServerConsole: onBackendConnect: gdb-server program client error Error: read ECONNRESET

There is the complete log:

What is the problem? 

Thank you!

Hi Emile,

I have got the same error using the sample code for nrf9160 AWS IoT.

The build function and flash function work flawlessly though, but just not debug.

I hope to get support for solving this issue too.

[MaLu]

Same thing here with an nRF9160 and NCS 2.0.2

Debugging with Ozone seems to works fine, but debugging with VSCode doesn't.

Hi,

We have been encountering this issue with some customers now. Could you attach the Support Information here?

Same here with NCS 1.7.0 on nRF52.

I guess the problem might be induced by an extension which was recently updated...

[Manuel]

As expected, it seems as an updated extension caused the Problem in my case: The issue could be solved by downgrading the extension "Cortex-Debug" from 1.6.0 (which was deployed yesterday) to the last version 1.4.4:
