I am using Yocto Kirkstone. I want to build and run the exemplary core-image-minimal for BBB. After the build, when I dd the SD card with this command:
sudo dd if=core-image-minimal-beaglebone-yocto.wic of=/dev/<media>
Everything works- I can boot from the SD card. The boot partition then includes of the following files/ directories:
am335x-boneblack.dtb am335x-bone.dtb am335x-bonegreen.dtb extlinux MLO u-boot.img zImag
Following different tutorials on how to copy the built files manually, there is no mention of the extlinux directory and am335x-bone.dtb am335x-bonegreen.dtb files (I think these blobs are for BB white and BB green, so not needed). But the thing is, my image wont boot (probably) because of the lack of the extlinux dir and the extlinux.conf file inside (its a guess). Why does it boot without that dir in the tutorials (i.e., here)?
