mikcatta Yes I believe all steps have been followed, the only thing I would mention is that I already had the SDK installed for compiling for the Thingy91, which was/is working.

Sorry for the delay @mikcatta. I didn’t see the notification you replied!

With the above being said, it’s difficult to add the NFED directory to an already existing NCS copy.

Have you tried compiling this code for the nRF91 Thingy?
How did you manage the install process of NCS?

Things may not work as expected if you’re using the Nordic’s install wizard/Segger Studio. I recommend you pull a fresh repo using the instructions here.

      Hi @jaredwolff

      I believe I did follow your instructions to the letter, the only difference being that I installed into C:\nRFConnectSDK\nfed rather than c:\nfed, but I can’t see that would of caused any issues? Maybe I should try that next……

      Unfortunately without the “build.ninja” file, it fails every-time unless I specify -p, odd or what?

      The install for the Thingy91 seemed to work and using Segger, rather than “west”, the build worked. Iam really not sure where to go with this now. I am no expert with the Nordic tools, I was just trying to get started.

        Installed into c:\nfed and it fails with the same error

        c:\nfed\nrf9160-feather\samples\blinky>west build -b circuitdojo_feather_nrf9160ns
        ninja: error: loading ‘build.ninja’: The system cannot find the file specified.

          mikcatta I believe I did follow your instructions to the letter, the only difference being that I installed into C:\nRFConnectSDK\nfed rather than c:\nfed, but I can’t see that would of caused any issues? Maybe I should try that next……

          Ahh gotcha. I was confused as to how wrote it earlier. This should not matter as long as everything (zephyr nrf etc are within the nfed directory)

          One thing I did notice is that this setup is using C:/gnuarmemb/bin/arm-none-eabi-gcc.exe as your compiler not C:\Program Files (x86)\GNU Tools Arm Embedded\9 2019-q4-major

          You may want to open the environment configuration as seen here and make sure that GNUARMEMB_TOOLCHAIN_PATH and ZEPHYR_TOOLCHAIN_VARIANT are set correctly.

              Hi @jaredwolff

              This is the output from the command, and it looks to me as if “gnuarmemb” is correct?

                  mikcatta this is so funky. Do you mind uploading your CMakeOutput.log and CMakeError.log? Sorry for the issues with this. Just when you think the bugs are ironed out, more come out of the woodwork!

                      mikcatta how did you init the NFED directory?

                      Did you do these steps?

                      cd C:\
mkdir nfed
cd nfed
west init -m https://github.com/circuitdojo/nrf9160-feather-examples-and-drivers --mr main

                      I did notice that my cmake is slightly older. How did you install it? Through choco?

                          yes did the “west init -m…..” command

                          Cmake I believe was installed from the installation routines (step 3) :- choco install cmake –installargs ‘ADD_CMAKE_TO_PATH=System’

                            mikcatta hmm ok! I’m updating my setup here to see if I can reproduce the error.

                                    @mikcatta can you delete your build folder and try again with west build -b circuitdojo_feather_nrf9160ns

                                      @jaredwolff Presumably that is the build directory in the C:\nfed\nrf9160-feather\samples\blinky directory?

                                      Deleted that directory and build using west build -b circuitdojo_feather_nrf9160ns and I still get the same error.

                                        Yes, C:\nfed\nrf9160-feather\samples\blinky\build delete the whole build directory if that’s where you’re running west build -b circuitdojo_feather_nrf9160ns

                                        mikcatta hmm so this error happens when the cmake cache is mucked up for some reason. The solution for Mac is this. working on a Windows solution..

                                              mikcatta try this:

                                              Open up powershell.exe in Adminstrator mode and run:

                                              choco uninstall cmake
choco install -y cmake --version 3.18.5

                                              Then delete your build directory and try again.

                                                  Hi @jaredwolff

                                                  Tried that, and cmake didn’t seem to be added to the PATH, so had to add it manually and now it reports as:

                                                  C:\nfed\nrf9160-feather\samples\blinky>cmake -version
                                                  cmake version 3.18.5

                                                  But I still get the same error as before:-
