nRF Connect for Desktop forces me to install J-Link but I have it already

[matt01]

I'm using nRF Connect for Desktop on Linux and updated today to v5.3.0.

I have J-Link V9.24a installed and it is available in $PATH. Also it works well with Programmer v4.7.4, current nrfutil and all other software from Nordic.

However I am not using Debian-like distro and I get annoying message "Install SEGGER J-Link" at every startup:

nRF Connect for Desktop requires SEGGER J-Link. The recommended version v9.24a is available for installation. Click "Install" to start.

As you can see on the screenshot I can't do anything but click on "Install". This opens super user authentication window which I click "Cancel" on, then the process fails with error message in another window and only then I can use the app normally. This is a bit cumbersome way to open the application.

Ideally this process should look for J-Link in PATH and don't suggest installation if it finds correct J-Link version. Also the initial window could have close button for quick cancellation.

I think the former worked in previous version because I used to see warnings about outdated J-Link after nRF Connect for Desktop updates.

Hi Mateusz,

Could you try placing the J-Link binaries in /opt/SEGGER/JLink as suggested in the following ticket:  JLinkARM DLL can't be found by the command "nrfutil device list" on Linux

I should have been more clear, apologies. I already have it there with the magic of symlinks, see my folder structure:

... etc

As I wrote, nrfultil just works. All JLink tools are in /opt/SEGGER/JLink. nRF Connect for Desktop must be checking something else.
