Hello,
I am currently learning about the Poky and meta-ti. I am trying to build
a custom image for the BBB. What I cannot get my head around right now
(amongst really many things related to this work), is how to figure out
which "am335x-boneblack.dts" file exactly is used by my build... When do
a search in the compiled build directory I get multiple sources:
lukasz@vmks:~/udemy-yocto/src/build-ti$ find . -name
"am335x-boneblack.dts"
./tmp/work-shared/beaglebone/kernel-source/arch/arm/boot/dts/am335x-boneblack.dts
./tmp/work/beaglebone-poky-linux-gnueabi/u-boot-ti-staging/1_2021.01+gitAUTOINC+3a5205e980-r33/git/arch/arm/dts/am335x-boneblack.dts
./tmp/work/armv7at2hf-neon-poky-linux-gnueabi/linux-libc-headers/5.4-r0/linux-5.4/arch/arm/boot/dts/am335x-boneblack.dts
./tmp/work/x86_64-linux/qemu-native/4.2.0-r0/qemu-4.2.0/roms/u-boot/arch/arm/dts/am335x-boneblack.dts
The layers I am using right now are:
lukasz@vmks:~/udemy-yocto/src/build-ti$ bitbake-layers show-layers
NOTE: Starting bitbake server...
layer path priority
==========================================================================
meta /home/lukasz/udemy-yocto/src/poky/meta 5
meta-poky /home/lukasz/udemy-yocto/src/poky/meta-poky 5
meta-arm-toolchain
/home/lukasz/udemy-yocto/src/meta-arm/meta-arm-toolchain 30
meta-arm /home/lukasz/udemy-yocto/src/meta-arm/meta-arm 6
meta-ti /home/lukasz/udemy-yocto/src/meta-ti 6
meta-oe
/home/lukasz/udemy-yocto/src/meta-openembedded/meta-oe 6
My MACHINE in local.conf is: beaglebone
I am trying to write a custom device tree overlay for the
am335x-boneblack.dts, but I have no clarity which am335x-boneblack.dts
is the one I am writing the overlay for (that is, which of the available
am335x-boneblack.dts is compiled during bitbake to the
am335x-boneblack.dtb and copied over to the images dir). All these files
are a bit different from one another (probably come in different
versions). How to check which one is used by the build?
I would appreciate all help!
