Hi, you can use nRF Connect for VS Code and choose the "nRF Connect" profile

or you can run "nrfutil sdk-manager toolchain launch --ncs-version v3.1.0 --terminal" (or whatever ncs version that you are using if it's newer than 3.0)

The error that you are seeing is most likely because the environment is not properly set up for west

Run these is you still run into errors for me to see what's wrong.

where west
west --version

Thank you for your support, we re-executed the procedure properly with appropriate binaries and environment paths and it worked as intended.
But now we are trying to execute west commands from the windows terminal (cmd/powershell) which is not happening and we are getting the following error -:

west flash
Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main
  File "<frozen runpy>", line 88, in _run_code
  File "C:\ncs\toolchains\0b393f9e1b\opt\bin\Scripts\west.exe\__main__.py", line 4, in <module>
ModuleNotFoundError: No module named 'west'

we have tried executing the command from appropirate ncs base locations as well as from the west.exe source.

How can we execute west related commands from the powershell terminal in windows?

Sorry for the late response. I was travelling.

That behaviour suggests that there is a key inconsistency.
1/ Can you double check if SB_CONFIG_BOOT_SIGNATURE_KEY_FILE is pointing to the right key file?
2/ Ensure the private key used to sign your application image is the same as the one you provisioned to the device
3/ Confirm that the application image is being signed during the build process and that no errors occur during signing

If you are still having trouble please send over the terminal/error log.

i added the nrfutil exe file to the location as mentioned - "C:\ncs\toolchains\b8b84efebd\nrfutil\bin\nrfutil.exe" and verified using "Get-Command nrfutil | Select-Object Path" which outputs the same path.
now the "west ncs-provision upload -s nrf54l15 -k private_key.pem" commands works with output as -

west ncs-provision upload -s nrf54l15 -k private_key.pem
nrfutil device x-provision-keys --key-file C:\Users\Admin\AppData\Local\Temp\nrfutil_lq2m1dbw\keyfile.json --traits jlink
Uploaded!

And on flashing the code, the device is getting stuck into bootlooder itself in the "FIH_PANIC;" of the main.c in bootloader.

Hi, where are you running the command from? If you are using VSCode, go to NRF Connect, open the terminal and run the command there.
if this doesn't work, run "Get-Command nrfutil | Select-Object Path" (in the VSCode terminal) or "where nrfutil" in CMD

or

"which nrfutil
type -a nrfutil" if Mac or Linux

The path should be something similar to this "C:\ncs\toolchains\b8b84efebd\nrfutil\bin\nrfutil.exe". If it's not, set it to the correct nrfutil.exe
