SOLVED Problem cross-compiling

tj

As the raspberry folks have released a new kernel (20210430), I'm trying to compile the drivers for a new camera of @MK. Following the instructions, at the last build command I get the error:

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs -j2
make[2]: *** No rule to make target 'arch/arm/boot/dts/overlays/csimx307-overlay.dtbo', needed by '__build'.  Stop.
make[1]: *** [scripts/Makefile.build:496: arch/arm/boot/dts/overlays] Error 2

What am I doing wrong? I've double checked that I did the four steps:

add driver sources
update Makefile and Kconfig
add dts files
change Makefile in dts folder

@tj said in Problem cross-compiling:

change Makefile in dts folder

You should edit this file:
arch\arm\boot\dts\overlays\Makefile

veye327.dtbo \
csimx307.dtbo \
cssc132.dtbo \

@veye_xumm Thanks for having a look. I had already added those lines. However I still get the error.

@tj please attach your Makefile let me take a look at it.

@veye_xumm Thanks for the offer. While posting the Makefile I noticed I had -overlay.dtbo in the filenames. Compiling now.
