Custom device tree

Opened this issue · 1 comments

How can i specify custom device tree file without rebuild uboot?

You can change the boot script (https://github.com/johang/sd-card-images/blob/master/2nd-stage-files/pre-2nd-stage-files-arm64/etc/initramfs/post-update.d/zz-update-uimg) so it uses a different dtb. Default is to use the dtb included in Debian/Ubuntu's kernel.
