Aloha, I was wondering if someone could advise on how I would go about creating a custom device tree based kernel?
I've created my meta-foo repo which includes my defconfig etc. The bit I'm stuck on is how I would create the steps that I would manually do, within Yocto. As in which files need what entries, below are the manual steps I would do: git clone git://kernel.repo.git git checkout branch I would then build a kernel zImage with: make ARCH=arm platform_defconfig make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j5 zImage I then need to build and append the dtb: git clone git://dts.repo.git git checkout branch I would then copy the motherboard.dtsi and processor.dts into kernel.repo/arch/arm/boot/dts Then do: make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- rtsm_ve-cortex_a15x2.dtb This creates a dtb entry in kernel.repo/arch/arm/boot To append the blob to the kernel I do: cat ./zImage ./rtsm_ve-cortex_a15x2.dtb | dd of=zimageProcessor.bin bs=4 conv=sync With the root tarballs I use manually I then have to create an initramfs enabled rootfs by doing: sudo sh -c 'find . | cpio --quiet -H newc -o | gzip -3 -n > ../filesystem.cpio.gz' Now I'm not sure whether the last step is required if I use Yocto or not, but I need to build the kernel with the dtb appended. Ant ideas? Many thanks, Andy _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
