Cadmium, The state-of-the-art Linux distro for RISC laptops that I could get my hands on (atm only ARM Chromebooks)

It also doesn't suck!

Hardware support:

Note: (FW) entries are meant to indicate that firmware(that is included in Cadmium) is needed for piece of hardware to work correctly.

Installation

• Make sure that you have developer mode unlocked

• Enable booting from usb, by running enable_dev_usb_boot in ChromeOS root shell accessible when you log in as root after pressing ctrl + alt + refresh.

• Reboot Once you have this out, continue with instructions:

• Edit ./config to reflect your board

• ./build-all /dev/sdX On a Linux machine(ChromeOS doesn't count(except in linux chroot)). For Debian rootfs, binfmt and debootstrap are needed to work correctly.

• When build-all is ran like ./build-all <file> <size>, it builds Cadmium to with size of (2G should be fine)

• Enable developer mode

• Plug pendrive into your laptop.

• Boot from USB

• After running ./install after connecting to internet, Cadmium will be installed on internal emmc memory

• To update kernel on eMMC memory run: ./install-kernel from pendrive

OR

• Enable developer mode(instructions are in the wiki for krane)
• Download and uncompress cadmium-<device>.tar.gz to your pendrive
• Boot from USB
• Run ./install

Binary drivers are unsupported in Cadmium and never will be

Dependencies on build machine

• Recent Linux distribution
• Binfmt when Debian rootfs is used
• debootstrap when Debian rootfs is used
• qemu-user-static when build machine can't run binaries for target machine
• vboot-utils u-boot-tools (vbutil_kernel, cgpt and mkimage) to pack kernel into format understandable by depthcharge
• gcc-aarch64-linux-gnu for compiling to ARM64 or gcc-arm-linux-gnueabihf for compiling to ARMv7
• curl to download the kernel
• bsdtar for writing the archive file (from the libarchive-tools package)
• f2fs-tools for creating the filesystem used by Cadmium
• parted to prepare gpt table to be modified by cgpt
• Build dependencies for kernel compilation
