VIM4 Download Android Source Code
Introduction
Android Source Code branch of Khadas VIMs is located on GitHub, and there are many different branches here. You can follow the steps to download the Source Code.
Steps
Install git-lfs tool to download Android 11.0 SDK
$ mkdir git_lfs $ cd git_lfs $ wget https://github.com/git-lfs/git-lfs/releases/download/v2.3.4/git-lfs-linux-amd64-2.3.4.tar.gz $ tar xvzf git-lfs-linux-amd64-2.3.4.tar.gz $ cd git-lfs-2.3.4 $ sudo ./install.sh $ git lfs install
1) Create an empty directory to store working files:
$ mkdir -p WORKING_DIRECTORY $ cd WORKING_DIRECTORY
2) Run repo init to download the manifest repository first:
$ repo init -u https://github.com/khadas/android_manifest.git -b khadas-vim4-r
3) Run repo sync to pull down the Android Source branch:
$ repo sync -j4
It will take approx one hour to complete the initial sync operation.
If repo sync operation failed, you need to run the command repeatly; or you can try with this script:
#!/bin/bash repo sync -j4 while [ $? = 1 ]; do echo "Sync failed, repeat again:" repo sync -j4 done
If needed, press Ctrl-\ to quit.
4) Based on different unbutu versions, the following operations may be required to pull large files(Otherwise, the corresponding file is small and incorrect). You need to go to the following three directories and use the 'git lfs pull' command to pull large files, otherwise an [error](https://forum.khadas.com/t/cannot-build-an-android/15886) will be reported during compilation:
vendor/amlogic/common device/khadas/kvim4-kernel device/khadas
xxx@server:/users/vim4$ cd vendor/amlogic/common xxx@server:/users/vim4/vendor/amlogic/common$ git lfs pull Git LFS: (6 of 6 files) 239.31 MB / 239.31 MB xxx@server:/users/vim4/vendor/amlogic/common$ cd - /users/vim4 xxx@server:/users/vim4$ cd device/khadas/ xxx@server:/users/vim4/device/khadas$ xxx@server:/users/vim4/device/khadas$ git lfs pull Git LFS: (2 of 2 files) 231.89 MB / 231.89 MB xxx@server:/users/vim4/device/khadas$ cd kvim4-kernel/ xxx@server:/users/vim4/device/khadas/kvim4-kernel$ xxx@server:/users/vim4/device/khadas/kvim4-kernel$ git lfs pull Git LFS: (4 of 4 files) 451.79 MB / 451.79 MB xxx@server:/users/vim4/device/khadas/kvim4-kernel$
5) Begin a new branch for development:
$ repo start <BRANCH_NAME> --all
