Why nRF Connect for Desktop always tries to copy nrfutil.exe to installed directory

[Colin Zhu]

Hi,

I have used nRF Connect for very long time, and have just upgraded to v5.0.1. The software seems to use a sandbox tech and restores nrfutil.exe to its default version which is 4.43MB. The problem is I can't update nrfutil core in nRF Connect Apps (such as Power Profiler). It returns the following error

2024-07-10T06:38:10.946Z ERROR Error while updated nrfutil core
2024-07-10T06:38:17.355Z ERROR Error: Failed to bootstrap core functionality before executing command.

Failed to install package

sandboxes\device\2.1.1\bootstrap\nrfutil-core-install-HbZpG1\nrfutil-x86_64-pc-
windows-msvc-7.12.0.tar.gz

using nrfutil command extracted from the same tarball.

See the details below for further information on the error.

        2: 系统找不到指定的文件。 (os error 2) while canonicalizing Z:\Cache\Temp\.tmpLCSG82

I then have to manually copy nrfutil.exe from C:\Users\colin\AppData\Roaming\nrfconnect\nrfutil-sandboxes\device\2.1.1\tmp\ to C:\Users\colin\AppData\Roaming\nrfconnect\ to run the Apps properly. But next time I open nRF Connect Launcher everything restores to default. Please advice how I can fix this issue or just disable sandbox feature. Many appreciates.

I'm currently running Windows10 Home edition 22H2

Hi,

The problem is I can't update nrfutil core in nRF Connect Apps (such as Power Profiler). It returns the following error

Could you tell me how you tried this?

Could you also tell me your nRF Command Line tools version?

Regards,

Priyanka

Hi,

The nRF Command Line tools version is 10.24.2, which is shown below.

C:\Users\colin> nrfjprog --version
nrfjprog version: 10.24.2 external
JLinkARM.dll version: 7.94e

What I did is simply install nRF Command Line tools, followed by nRF Connect Desktop v5.0.1 x64 (also tried other version above v4.4) and JLink v7.94e(bundled with current version).

Then open Power Profiler in nRF Connect for Desktop gave the above error.

Hi,

I am not able to replicate this unfortunately. But could you try to manually update the nrfutil and see if this helps you?

Download the latest version of nrfutil from the Nordic Semiconductor GitHub repository. Then extract the downloaded files manually to a temporary directory. Replace the nrfutil.exe file in C:\Users\colin\AppData\Roaming\nrfconnect with the new version.

Hi,

Thank you for your quick response. I'm afraid the solution won't help because the repository is deprecated from Sep. 2022. The nRF Connect Desktop downloads the nrfutil from the official site.

I've temporarily bypassed the problem by manually copy nrfutil.exe every time nRF Connect launches, though it's quite inconvenient.

I'll wait and see if anyone encountered this problem.
