Evening @jaredwolff

I’ve got a bit further on Linux, but not quite to point of compiling !

Both Win & Ubuntu report:

- The C compiler identification is GNU 9.2.1
-- The CXX compiler identification is GNU 9.2.1
-- The ASM compiler identification is GNU

I believe I have a compile on Ubuntu !

[158/158] Generating zephyr/merged_domains.hex

Had to follow these instructions on the Nordic site for the Python dependencies, which are ever so slightly different to the instructions on your site. [https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#installing-the-required-tools]

pip3 install –user -r zephyr/scripts/requirements.txt
pip3 install –user -r nrf/scripts/requirements.txt
pip3 install –user -r bootloader/mcuboot/scripts/requirements.txt

I am using CMake 3.18.5 on Ubuntu, but I am not sure that was the issue.

Hi @jaredwolff Just to clarify….

I have created a ~/.zephyrrc file which contains

export PATH=$PATH:/home/mike/cmake-3.18.5-Linux-x86_64/bin
export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb
export GNUARMEMB_TOOLCHAIN_PATH="~/gnuarmemb"

I installed cmake-3.18.5 from source, so it installed it locally. Again not sure, that was the issue. The GNUARMEMB was installed into the directory ~/gnuarmemb

On first compile, I had to add the “-p” command, so ran west build -b circuitdojo_feather_nrf9160ns -p

Some of these steps may not be necessary, but it seems to compile a hex file now at least on Ubuntu. Next step will be to see if I can flash it from the VM or maybe in needs to be transferred to Windows for programming the board, but that’s tomorrow little game.

HI @jaredwolff

Apologises, I thought I’d have a go at compiling one of the main apps for the Feather at https://docs.jaredwolff.com/nrf9160-agps-sample.html

From the /home/mike/nfed/nrf/samples/nrf9160/nrf_cloud_agps, I’ve added the additional lines to the prj.conf, but when I try and compile it says:-

**/home/mike/nfed/nrf/samples/nrf9160/nrf_cloud_agps/prj.conf:61: warning: attempt to assign the value '"feather-"' to the undefined symbol NRF_CLOUD_CLIENT_ID_PREFIX**

Without that line, it compiles just fine. What I am doing wrong here please?

Hi @jaredwolf I was just following the instructions on your website, if that doesn’t work, can you clarify that on the site at the URL https://docs.jaredwolff.com/nrf9160-agps-sample.html ?

@jaredwolff I use the pre-built binary, can I set a custom APN for use with my O2/Telefonica SIM?

Hi @jaredwolff

Yes!!!! That compiled ok on my Windows machine, thank you so much for struggling on with this.

My Hologram SIM said it was out of credit after 10 minutes of use, but now showing as “Connected”, so I am a bit confused as to whether that SIM is working or not. I will try again with the O2/Telefonica SIM, now I know how to set the APN.

Cheers for your assistance

Have a great Xmas and thankyou again for resolving this issue @jaredwolff , hopefully it will end up helping others.
