Create .dtbo overlays file instead of direct include in the am335x-boneblack.dts file

Hello everyone,

I have severals interrogations about creating overlays .dtbo file for the cape i’m using on the BBB instead of .dtsi directly include in the original .dts file, i would like to know how do i structure the overlay.dts file to make my includes works, and that way i could keep default configuration of beaglebone black and add the overlay file throught the different kernel and that would be much more easier for me.

Also what is the parameter in uEnv.txt to take in consideration the new dtbo file in the u-boot loader, thanks

here is the structure i did but it doesnt seems to work when i compile using dtc i get several error message about syntaxe error on the block fragment 2 for example
bb.txt (13,2 Ko)

thanks everyone
