nRF Connect SDK v3.0.2: Device not found / nrfjprog not found


Descrition:
--------------------
Hello,

I've installed my toolchain on a new computer (WIN11), i have an nRF528410 and use a Segger J-Link Base. What I installed:

	> J-Link Software and Documentation Pack v8.56a, with USB driver suing C:\Program Files\SEGGER\JLink_V856a\USBDriver\InstDrivers.exe
	> VS Code
	> nRF Connect Visual Studio Code Extension Pack
	> nRF Util:
		* winget install nrfuti
		* with the commands device, completion, toolchain-manager installed

With this installation i can add the build-configurations, build these, but no device is detected.

With SEGGER Embedded Studio and my J-Link installation I can build & flash...

According to VS code connected devices doesn't show debugger i downgraded nRF Connect for VS Code to 2025.1.127. After that it showed my device under "CONNECTED DEVICES" but i still could not flash. I got the error in the terminal:

	-- west flash: rebuilding
	[0/5] Performing build step for 'O3G3_Firmware'
	ninja: no work to do.
	[2/5] No install step for 'O3G3_Firmware'
	[3/5] Completed 'O3G3_Firmware'
	[4/5] cmd.exe /C "cd /D C:\Development\nrf_connectsdk_study\Projects\O3G3_Firmware\build\debug\_sysbuild && C:\ncs\toolchains\0b393f9e1b\opt\bin\cmake.exe -E true"
	-- west flash: using runner nrfjprog
	-- runners.nrfjprog: mass erase requested
	-- runners.nrfjprog: reset after flashing requested
	FATAL ERROR: required program nrfjprog not found; install it or add its location to PATH

Hence, i wanted to install the nRF Command Line Tools, but on the download page [https://www.nordicsemi.com/Products/Development-tools/nRF-Command-Line-Tools/Download] it is indicated that this is replaced by nRF Util. Therefore I did not install it.

Can you help me? Should I install the nRF Command Line Tools?

Thanks and best regards
