VSCode Connect SDK flashing fails when multiple devices are attached

[Fabian01]

Since about a week or two ago, I cannot flash (or debug/reset etc.) my device from the VSCode nrfConnect extension, when more than one device is connected to my PC.

I am using the nrf5340_dks and audio_dks, but the type of devices connected does not make a difference.

I always get this error:

Error: One or more batch tasks failed:
 * 1050174490: Emulator error: Failed to open connection (Generic)

FATAL ERROR: command exited with status 1: nrfutil --json device x-execute-batch --batch-path /build/generated_nrfutil_batch.json --serial-number 1050174490

Once I unplug the other devices, it works fine again. 

I am on Linux (Manjaro) using the latest nrfConnect extension (but have tried to revert to older versions with no change)

Thanks in advance!

Hi,

What nrfutil version do you use?

Could you try to update your nrfutil version?

Hi Priyanka,
I ran self-upgrade and got:
nrfutil is already the newest version (8.1.1)

Hi,

There have been similar issues reported when multiple J-Links were connected simultaneously along with several active VS Code instances. So, could you try to maybe close all VS Code instances and other Nordic tools, and also making sure there are no multiple J-Link instances.

Hi,

I have checked and have no other instances of VSCode (or nrfutil or any JLink instances) runnning in the background. I have also restarted multiple times since then.

But if you cannot replicate the issue on your side, i guess it is an issue with my system somehow..

Thanks,

Are you able to replicate this issue on another PC or system?
