Project

This projects aims to create an upgradable AOSP build system for the OnePlus 5 (Cheeseburger) and the OnePlus 5T (Dumpling). No repository from AOSP is changed: no commit over AOSP is at the moment present on these sources.

All the changes are provided in separate repositories: this allows to upgrade Android with minimal effort, potentially also for future major versions.

Most of the added repositories is provided by LineageOS or CAF, so thanks to them for those repos.

Build instructions

Follow the instructions from Google to setup a machine to build Android 14: https://source.android.com/setup/build/initializing

Then, sync all the sources:

$ repo init -u https://android.googlesource.com/platform/manifest -b <AOSP tag>
$ cd .repo
$ git clone --branch a14/gl https://github.com/OnePlus-5-T/local_manifests.git local_manifests
$ cd ..
$ repo sync -c --no-clone-bundle --no-tags

then:

$ source build/envsetup.sh
$ lunch aosp_cheeseburger-ap1a-user
$ make -j12

the images will be available in out/target/product/cheeseburger.

To build an OTA, from the Android sources root directory:

$ bash vendor/rs/ota_build/ota_build.sh aosp_cheeseburger-ap1a-user
$ bash vendor/rs/ota_build/ota_build.sh aosp_dumpling-ap1a-user

and the OTA zip will be available in out/target/product/<product>.

Flash instructions

The images can be flashed using fastboot:

$ fastboot flash boot out/target/product/cheeseburger/boot.img
$ fastboot flash recovery out/target/product/cheeseburger/recovery.img
$ fastboot flash system out/target/product/cheeseburger/system.img
$ fastboot flash vendor out/target/product/cheeseburger/vendor.img

Format data if this is a first flash:

$ fastboot format userdata

Note that not all the fastboot versions support the 'format' command.

The OTA can be flashed from the recovery (using the 'ADB sideload' feature) or using third party recoveries like TWRP.

To build for Dumpling, run the same commands with 'dumpling' instead of 'cheeseburger' in commands and paths.

Build the kernel

The ROM sources include a prebuilt kernel. To build a kernel from sources and update it in the Android sources, follow these instructions.

Download the sources and the cross compilers (needed only the first time):

$ cd ~
$ mkdir kernel_build
$ cd kernel_build
$ git clone --single-branch --branch 4.14.314/msm8998_oneplus https://github.com/OnePlus-5-T/4.14-kernel-oneplus-msm8998 kernel_oneplus_msm8998
$ git clone --depth 1 -b android12L-release --single-branch https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/aarch64/aarch64-linux-android-4.9/ prebuilt_aarch64
$ git clone --depth 1 -b android12L-release --single-branch https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.9/ prebuilt_arm
$ git clone --depth 1 -b android-13.0.0_r0.70 --single-branch https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86 prebuilt_clang
$ git clone --depth 1 -b android-13.0.0_r0.70 --single-branch https://android.googlesource.com/platform/prebuilts/gas/linux-x86 prebuilt_clang_triple
$ git clone --depth 1 -b android-13.0.0_r6 --single-branch https://android.googlesource.com/platform/prebuilts/build-tools prebuilt_tools

Build the kernel:

$ CC_ARM32_PATH=~/kernel_build/prebuilt_arm/bin
$ CC_ARCH64_PATH=~/kernel_build/prebuilt_aarch64/bin
$ CLANG_PATH=~/kernel_build/prebuilt_clang/clang-r458507/bin
$ CLANG_BIN=${CLANG_PATH}/clang
$ CLANG_TRIPLE_BIN=~/kernel_build/prebuilt_clang_triple/aarch64-linux-gnu-
$ MAKE_PATH=~/kernel_build/prebuilt_tools/linux-x86/bin
$ PATH="${PATH}:${CLANG_PATH}"
$ DEFCONFIG=msm8998_oneplus_android_defconfig

$ cd ~/kernel_build/kernel_oneplus_msm8998
$ git pull
$ ${MAKE_PATH}/make O=out ARCH=arm64 CC=${CLANG_BIN} LLVM=1 LLVM_IAS=1 ${DEFCONFIG} -j8
$ ${MAKE_PATH}/make O=out ARCH=arm64 CROSS_COMPILE_ARM32=${CC_ARM32_PATH}/arm-linux-androidkernel- CROSS_COMPILE=${CC_ARCH64_PATH}/aarch64-linux-androidkernel- CC=${CLANG_BIN} LLVM=1 LLVM_IAS=1 CLANG_TRIPLE=${CLANG_TRIPLE_BIN} -j6

Kernel headers can be generated with the following (after configuring the environment with the same variables used to build the kernel) (assuming that the Android build directory is ~/android_build_directory/):

$ ${MAKE_PATH}/make headers_install ARCH=arm64 LLVM=1 LLVM_IAS=1 INSTALL_HDR_PATH=~/android_build_directory/vendor/rs/kernel-headers/
$ cp -r ~/android_build_directory/vendor/rs/kernel-headers/include/* ~/android_build_directory/vendor/rs/kernel-headers/
$ rm -rf ~/android_build_directory/vendor/rs/kernel-headers/include
$ rm -rf ~/android_build_directory/vendor/rs/kernel-headers/techpack
$ cd ~/android_build_directory/vendor/rs/kernel-headers/
$ find . -name "*.cmd" -type f -delete
$ cd -

Extra patches

Some patches are needed over AOSP to fix specific issues. The patches can be applied with the following commands, after the repo sync:

$ cd aosp_patches
$ ./apply_patch.sh <AOSP tag>
