This is shipped as bredos-tools, compatible with any system architecture, on the BredOS-any repository.
It is an integral part of BredOS. bredos-tools should be installed by default.
sudo pacman -S bredos-tools
This package contains a plethora of tools with the sole purpose of easing development, maintenance and the general use of BredOS.
BredOS includes a utility to restrict GRUB boot options with a password.
This prevents unauthorized users from booting non-default entries or editing boot parameters.
sudo grub-password
You’ll be prompted to enter and confirm a password.
Once set, only the default GRUB entry can be booted without authentication.
sudo grub-password -d
This removes the password restriction and restores normal GRUB behavior.
The configuration is stored in /etc/grub.d/99-bredos-grub-password.
The script regenerates GRUB config automatically via grub-mkconfig.
This modifies/etc/grub.d/10_linux, do not revert it manually!
dtc, simply runyay -S dtc
The script is a wrapper to dtc, performing automatic gcc preprocessing, linking and generation of needed files.
It makes generation and testing of device trees a lot simplier.
It also automatically determines and generates base device trees or overlays accordingly.
Installing an incorrect device tree on your device will render it inoperable.
Be careful, perform backups and ensure a contigency plan.
-h to show its usage:usage: dtsc [-h] [-o OUTPUT] [-i INCLUDE] [-k KERNEL] [input]
Compile a Device Tree Source (DTS) file into a Device Tree Blob (DTBO or DTB).
positional arguments:
input Input DTS file
options:
-h, --help show this help message and exit
-o, --output OUTPUT Output file (default: makes input_filename.dtb)
-i, --include INCLUDE
Source of additional device tree files (optional)
-k, --kernel KERNEL Manualy specify a kernel source path (default:
autodetect)
Example: ./compile_dts.py my_device_tree.dts -o output.dtbo
The script expects an input .dts file. If no output is specified, it generated a matching-name .dtb
The output filename can be set with the -o parameter.
If you have more than one kernels installed onto your system, you should specify the kernel path to link against.
dtsc example.dtc -k /usr/src/linux-rockchip-rkr3 -o example.dtbo
If you have a single kernel installed, this will automatically be detected.
If you're compiling a base device tree and not an overlay, you'll need your kernel's full sources, which are not shipped.
This is because these trees require the inclusion of other .dtsi device trees.
To compile such a DT, clone your kernel's repository using git, onto a known path.
linux-rockchip-rkr3 kernel:git clone https://github.com/BredOS/linux-bredos
Then run dtsc as you would, but with the -i flag, specifying the folder at which the files it wants to link against are.
dtsc rk3588-example-board.dts -i /path/to/linux-bredos/arch/arm64/boot/dts/rockchip -o rk3588-example-board.dtb
