VScode nrf connect plugin connected devices can not display the development board device serial number.

[han666]

Hello Nordic Team!

I updated to version 5.0.0 of NRF Connect for Desktop and since then, when I try to program my development kit in VS Code, it can appear as connected but can't get the device serial number which lead to flash failed. The Toolchain Manager version is v2.6.0 and the NRF Connect SDK version is v2.6.0. I have tried refreshing the "connected devices", but the problem persists. I uesd nRF5340 audio DK.

Hello, 

Can you please share more information on what is failing when trying to flash? Do you get any errors when trying to flash?

What exact steps are you doing? This will help me reproduce the issue on my side.

Thanks!

Kind regards,
Øyvind

Can you please provide the output from running the following command in command line: nrfjprog --version

[han666]

nrfjprog version: 10.24.2 external
JLinkARM.dll version: 7.94e

[Øyvind]

Have discussed internally and we are wondering if the legacy drivers from JLink are installed on you computer? E.g. the following screenshot show what it should look like

If these are missing can you please update nRF Connect for Desktop to v5.0.1? 

[han666]

Only installed this one, and I will try to update nRF Connect for Desktop to v5.0.1.
