I am trying to build zephyr sample code that is meant for board A for board B (i.e. build was written for code A but I need to change it so that it works with board B). I keep coming across this error and I am not sure how to get past it. I have replaced the /board, /soc, and /dts subfolders with appropriate files for my board. I changed the Makefile to target my board and it is successfully finding it.
This is the error:
cmake -B build -DBOARD=my_project_name ./

I have already checked to make sure that soc.h has #include <devicetree.h>. I'm not sure what else I can try now so any help is appreciated. Thanks!
Found the solution: I had to add dts_fixup.h to the bottom of my soc folder.
