Installation
-
Make sure that you have developer mode unlocked
-
Enable booting from usb, by running
enable_dev_usb_bootin 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/sdXOn a Linux machine(ChromeOS doesn't count(except in linux chroot)). For Debian rootfs, binfmt and debootstrap are needed to work correctly. -
When
build-allis 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
./installafter connecting to internet, Cadmium will be installed on internal emmc memory -
To update kernel on eMMC memory run:
./install-kernelfrom pendrive
OR
- Enable developer mode(instructions are in the wiki for krane)
- Download and uncompress
cadmium-<device>.tar.gzto your pendrive - Boot from USB
- Run
./install
Binary drivers are unsupported in Cadmium and never will be
