Hello, I'm running an example of channel sounding using nRF54L15.
The build is fine, but the following error occurs during flash.
Python is using 3.12.4 version.
As you can see, we're using protobuf version 3.19.6 as well. (The same error occurred in 3.20.0 version)
But I keep getting protobuf errors, how do I fix it?
-------------------------------------------------------------------------
I solved this problem, but another problem occurred.
ModuleNotFoundError: No module named 'constants'
Hello, thank you for your answer.
Initially, I encountered a version-related error with protobuf, so I ran the following command:
C:\ncs\toolchains\0b393f9e1b\opt\bin\python.exe -m pip install protobuf==3.20.3
After that, I started getting a 'constants' error.
ModuleNotFoundError: No module named 'constants'
I am using SDK v3.0.0, which I downloaded via nRF Connect for Desktop. and I'm using Python 3.12
I'll be waiting for your reply.

I referred to the following post on Nordic DevZone:
RE: nrfutil ModuleNotFoundError: No module named 'constants'
I did some research and found that issues occur with Python 3.10 and above because some outdated packages reference attributes like collections.Hashable, which no longer exist.
Does this mean that SDK v3.0.0 cannot run on Python 3.12?
I see. I just tested building the channel_sounding_ras_initiator with both NCS v3.0.0 and v3.0.1 (I recommend that you move to 3.0.1), and none of them triggered any protobuf issues. I do see from your build log that it was, for some reason, trying to use your local version of python, located in "C:\Users\SJIT\AppData\Local\Programs\Python\Python312\Scripts\..." rather than the one from your toolchain.
Also, after you "fixed it" by installing PyYAML, I am not sure what effect that will have on the toolchain. I suggest you remove the toolchain and reinstall it.
After you do that, try the following. Make sure that the active build is the application that you are trying to build, and then click:
Make sure that the toolchain listed is the one you are trying to use. Now, in that terminal, navigate to the root folder for the application:
cd ..\..\
and use this command to build:
west build -b nrf54l15dk/nrf54l15/cpuapp -d build_2
Does that build without any errors?
Best regards,
Edvin
Hello,
Unfortunately, as shown in the image, I tried using the Build and Flash buttons in the nRF Connect SDK Toolchain v3.0.1, but the same error kept occurring.
However, I was able to resolve the issue and successfully flash the device.
I tried several methods:
Downloaded Python 3.10 and configured both the interpreter and system PATH to use it.
I downloaded nrfutil from www.nordicsemi.com/.../nrf-util, manually moved it to the folder C:\ncs\toolchains\0b393f9e1b\opt\bin\Scripts, and ran the command C:\ncs\toolchains\0b393f9e1b\opt\bin\Scripts\nrfutil.exe install device

Hello,
As you mentioned, I ran the following command:
west build -b nrf54l15dk/nrf54l15/cpuapp -d C:\ncs\channel_sounding_ras_initiator\build
-- west build: generating a build system CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. -- Configuring incomplete, errors occurred!

However, I encountered an issue with Ninja,
but I was able to resolve it by adding the following to the PATH:
set PATH=C:\ncs\toolchains\0b393f9e1b\opt\bin;%PATH%
and the build was successful.
However, when I first tried to flash using this command:
C:\ncs\v3.0.1>west flash -d C:\ncs\channel_sounding_ras_initiator\build
an error occurred.
