nRF52840 with Zephyr - Project version control

[newUser]

Hi,

Currently I am setting up my work environment. I have a simple Zephyr project running on our custom board with the nRF52840, so a modified example and a custom board folder.

Now I would like to push these changes to our git server.

What is the best way to do this? I would like to push our source code (modified example), and the zephyr/boards/ folder containing our custom board definition.

Thank you!

I'd recommend reading about custom board definitions. You can place them wherever you wish, and using your CMakelists.txt file tell the project where it is. I prefer this method because you can keep all of your project files outside of the zephyr directory. Then you could have a bash script to initialize Zephyr/NCS to the right version in your repo to get everything set up.

Custom Out of Tree Boards

Hi Marciano-PL,

Thank you for your response. I have moved the project out of the zephyr folder, which works.
However, moving the board file out of the zephyr folder leaves me we an error. It cannot find the #included file referenced in the .dts file. That file in turn also references some files, so if possible I would like to tell the toolchain where it should look for those files, instead of manually editing those files and including them all manually in my folders.

Is this possible?

The problem is with #include <nordic/nrf52840_qiaa.dts>

Hi,

I am not sure what th eproblem is, to be honest. But you can see how out of tree boards are defined by referring to the Out Of Tree Board sample. This sample also builds if you move it out of the zephyr tree. In what way does your differ? If you make no progress, can you upload your project here?

Thank you Einar, that sample helped me out. I was missing the BOARD_ROOT directive in the CMakeLists.txt

Hi,

I am glad to hear it worked. Thanks for letting us know what the problem was, that could be useful for others later.
