Trouble booting in Gentoo

[tdiggitydog]

You seem to be missing the line for the dtb,, often just after kernel/Image
fdt  /some-path  (fdt=flattened device tree)
it can be relative to extlinux,,,  ../dtbs/etc OR if 2 partitions /dtbs/etc
OR if 1 partition /boot/dtbs/etc
Remember, dtb is loaded BEFORE initrd which is where filesystem becomes complete
uboot (which is what loads dtb) only knows about the partition where it found extlinux.conf (or boot.scr)
So, in a 2 partition setup thinks boot partiiton is /

Thanks for the reply!


I added this line to my extlinux.conf

Code:

fdt /dtbs/5.11.16-pinebookpro-arm64/rockchip/rk3399-pinebook-pro.dtb

so, the file now looks like this:

Code:

default l0
menu title U-Boot menu
prompt 0
timeout 50


label l0
    menu label Gentoo Linux 5.11.16-pinebookpro-arm64
    linux /vmlinuz-5.11.16-pinebookpro-arm64
    fdt /dtbs/5.11.16-pinebookpro-arm64/rockchip/rk3399-pinebook-pro.dtb
    append  initrd=/initramfs-5.11.16-pinebookpro-arm64.img root=LABEL=GENT-ROOT console=tty1 rw video=eDP-1:1920x1080@60

label l0r
    menu label Gentoo Linux 5.11.16-pinebookpro-arm64 (rescue target)
    linux /vmlinuz-5.11.16-pinebookpro-arm64
    fdt /dtbs/5.11.16-pinebookpro-arm64/rockchip/rk3399-pinebook-pro.dtb
    append initrd=/initramfs-5.11.16-pinebookpro-arm64.img root=LABEL=GENT-ROOT console=tty1 rw video=eDP-1:1920x1080@60 systemd.unit=rescue.target

I wasn't sure which .dtb file to use, since there are so many (in the subdirs found in /boot/dtbs/5.11.16-pinebookpro-arm64/). So i copied the the file "rk3399-pinebook-pro.dtb" from my Manjaro system to the gentoo sd card.

So after copying the file and the adding that line in my extlinux.conf, I am still unable to boot, but it no longer goes into a boot loop. It stays powered on until I force it off, and the screen never turns on. So hopefully this made some progress at least.

Do you think maybe I ought to use a different .dtb file in my extlinux.conf?

Here is a list of all of them found on the sd card. The files under the "rockchip" directory are ones I copied from my manjaro system.

Code:

gentoo # pwd
/boot/dtbs/5.11.16-pinebookpro-arm64
