This repository is used to build a generic systemimage for Halium-compatible operating systems.
This is a "device tree", and as such it can be built by loosely following the instructions at docs.halium.org; please see that page for a list of build dependencies and more explicative informations on each of the build steps.
Assuming that you have all the build dependencies and the repo tool, you
should run the following commands:
# Get all the needed repositories for a Halium-based build
repo init -u https://github.com/Halium/android -b halium-10.0 --depth=1
A copy of this very repository will be created in
device/halium/halium_arm64/; if you are interested in trying out a
modification or branch, apply your changes in the repo located in that
directory before proceeding:
# Get the required repositories for this specific build
./halium/devices/setup halium_arm64
# Apply Halium patches to the Android source tree
hybris-patches/apply-patches.sh --mb
# Setup the build environment
source build/envsetup.sh && breakfast halium_arm64
# Build the raw system image
mka rawsystemimage
After some time (depending on the machine you build on), the output will be in
out/target/product/halium_arm64/android-rootfs.img.
You can replace the android-rootfs.img via ssh:
# Transfer android-rootfs.img to the device
scp out/target/product/halium_arm64/android-rootfs.img [email protected]:/tmp/android-rootfs.img
# Update android-rootfs.img
ssh [email protected] "sudo mount -o rw,remount /"
ssh [email protected] "sudo mv -v /tmp/android-rootfs.img /var/lib/lxc/android/android-rootfs.img"
# Reboot the system to use the new android-rootfs.img
ssh [email protected] "sudo systemctl reboot"
