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: 

[2022-08-23T15:57:09.458Z] SERVER CONSOLE DEBUG: onBackendConnect: gdb-server session connected. You can switch to "DEBUG CONSOLE" to see GDB interactions.

Can confirm that downgrading the Cortex-Debug Extension fixed the problem!

Hi,

We have received reports of this and are working on a solution. At present, the workaround is, as mentioned by @manuel hulliger  to downgrade the Cortex-Debug extension to the previous version (v1.4.4)

-Priyanka

[mnor]

From what I can tell, it has to do with the version of gdb that Segger JLink GDB server is using. Cortex-Debug is only allowing versions 9 and above, whereas according to Cortex-Debug the JLink GDB server is based on version 8. I've tried upgrading to the latest Jlink software package but same problem.

[hkswan]

I started having this issue when Cortex Debug upgraded to 1.6.0 two days ago.  Ripping my hair out even though I'm mostly bald on top.  Anyway, I can confirm that downgrading to Cortex Debug 1.4.4 restored debugging capability.
