VS Code nRF Connect Extension nrfutil version issue

Hi Hieu,

Looks like the issue was conflicting USB devices causing things to get confused. I have a test system setup with a bunch of other devices connected (aka a nRF Dongle, JLink, etc.).

After I unplugged all of that stuff I am able to flash/debug the nRF9161 board.

See this post showing more details about the problem:

nrfutil-device.exe fails if a USB-serial adapter is connected to computer

Hi Hieu,

I am also unfamiliar with the generate batch file feature and have no end goal with it. It seems to just be something that is generated automatically as part of the normal nRF build process when using the VS Code Extension.

For the actual build I am just using the UI to do the "Build" and "Flash" processes, so it is opening a terminal window in VS Code like you said. So I would think it would be using this built-in nrfutil as you suggested, here is a screenshot of the full output:

There is another error there that I'm not familiar with regarding a 'None' value in that image so not sure if that is something causing a problem.

For further debugging I was opening an external Powershell that showed me the mismatch version error I mentioned previously, but perhaps there are two different errors depending on which environment I use.

I will try to uninstall nrfutil from my machine to see if it is causing issues with the VS Code extension's version of it, and also attempt on another machine that doesn't have any nrfutil/Nordic packages installed to see if that helps.

Hi tnesheim1,

I am unfamiliar with generate batch file feature. What is your end goal with this?

The toolchain runs its own copy of nrfutil and installed command, independent from what you install on your system.

How did you open the Powershell window to run the nrfutil command? If you are using Nordic's VS Code extension, you can use the "Create Shell terminal" feature to open a PowerShell with environment initialized to the same one your build configuration needs to use.
