=== Build custom LineageOS image ===

Prerequisite: You will need a Linux (preferably Ubuntu 20.04) machine with at least 16GB of RAM, at least 100GB of disk space (SSD), and at least 4 CPU threads.

Additionally you will need a lot of time. The whole process could take days to finish depending on your hardware.

==== Build Android TV flavor ====

You can then follow any generic LineageOS build guide like [https://wiki.lineageos.org/devices/I01WD/build this]. However there are a few things specific to Radxa Zero:

1. Choose <code>lineage-18.1</code> branch.

2. After running <code>repo sync</code>, edit <code>.repo/local_manifests/roomservice.xml</code> and add the following line before <code></manifest></code>:

 <project depth="1" name="TheMuppets/proprietary_vendor_amlogic" path="vendor/amlogic" />

Then run <code>repo sync</code> again.

3. Run <code>source build/envsetup.sh</code>.

4. Run <code>breakfast radxa0</code> instead of <code>breakfast I01WD</code>.

5. No need to run <code>extract-files.sh</code>.

6. You will need to build the bootloader with the following commands:

 git clone https://github.com/Stricted/deadpool_u-boot_build ~/deadpool_u-boot_build
 cd ~/deadpool_u-boot_build
 ./build_radxa0.sh
 cp uboot-bins/u-boot.bin ~/android/lineage/device/radxa/radxa0/factory

7. Run <code>croot</code>.

8. Run <code>m aml_upgrade</code> back inside LineageOS instead of <code>brunch I01WD</code>.

This will get you an Android TV build of LineageOS 18.1, located at <code>out/target/product/radxa0/aml_upgrade_package.img</code>. You can flash it with [[Zero/install/eMMC_aml_tool | aml-flash-tool]].

==== Build standard Android ====

To build normal Android, please change the content of <code>device/radxa/radxa0/lineage_radxa0.mk</code> to match [https://gist.github.com/sobrinho/d37296f76f3ce0fbfa3cbf15730d639b this gist], and change this line from <code>device/amlogic/g12-common/BoardConfigCommon.mk</code>:

 BOARD_KERNEL_CMDLINE := androidboot.dtbo_idx=0 androidboot.boot_devices=ffe07000.emmc otg_device=1

to this:

 BOARD_KERNEL_CMDLINE := androidboot.dtbo_idx=0 androidboot.boot_devices=ffe07000.emmc otg_device=1 androidboot.selinux=permissive

If you already built the Android TV image, you only need to run <code>breakfast lineage_radxa0</code>, <code>croot</code> and <code>m aml_upgrade</code> to generate the image in the same output location.
