[yocto] How do I generate a dtb for my board support package?

[Peter Spierenburg]

I've discovered the problem. It looks like my SRC_URI entries aren't placing my .dts and .dtsi files in the correct locations. If I manually copy those files to: poky/build/tmp/work-shared/adzs-sc589-ezlite/kernel-source/arch/arm/boot/dts then the build will produce a .dtb file as expected.


How do I alter the SRC_URI instruction in my .bbappend file to specify the correct destination directory?

Thanks Maciej,


I did add a patch to SRC_URI in my linux-yocto_4.12.bbappend file. Does the entry belong somewhere else instead?


Peter.

You are building linux-yocto. You need to either add a patch to SRC_URI which adds this
dtb target to linux source, or build from a different repository, where this support is already
included. I would check from which linux tree they build kernel in buildroot BSP.
You will also need proper kernel configuration file for your board.
