[solved] Unable to build new board part 2 - Partition configuration fails

[silent kestrel]

So far I think I fixed most of my syntax errors, but now I get the following build error:
https://pastebin.com/gJ5Qfshm
And here is my repository and the dts file that contains the partition configuration:
https://github.com/PercyJW-2/zmk-config/blob/master/boards/arm/popcorne/popcorne.dts
I alredy serached the resulting combined dts (https://pastebin.com/aZW1rapc) for any occurances of #address_cells = <2>; but did not find anything

[silent kestrel]

I think I forgot to define the code partition for zmk
