1.删除无关文件

从迅为获得安卓源码，解压
sudo tar -vxf rk3588_android12_20220801.tar

该源码含有编译过程中产生的文件，进入源码所在目录，执行
cd u-boot
make distclean
cd …

rm -rf u-boot/fit/uboot.itb
rm -rf u-boot/tools/loaderimage

cd kernel-5.10
make distclean
cd …
rm -rf kernel-5.10/arch/arm64/boot/Image
rm -rf kernel-5.10/arch/arm64/boot/Image.lz4
rm -rf kernel-5.10/arch/arm64/kernel/vdso/vdso.so
rm -rf kernel-5.10/arch/arm64/kernel/vdso/vdso.so.dbg
rm -rf kernel-5.10/boot.img
rm -rf kernel-5.10/resource.img
rm -rf kernel-5.10/zboot.img

删除原有的.git文件
find . -name “.git” | xargs rm -rf

2.创建本地仓库

git init
git add .
git commit -am “首次提交”

3.首次完整编译源码

报错
error: vendor/rockchip/hardware/interfaces/codec2/Android.bp:1:1: module “c2_ver
sion”: module source path “vendor/rockchip/hardware/interfaces/codec2/.git/HEAD”
does not exist
error: hardware/rockchip/libmpimmz/Android.bp:24:1: module “gen_mmz_version”: mo
dule source path “hardware/rockchip/libmpimmz/.git” does not exist
error: hardware/rockchip/libhwjpeg/Android.bp:1:1: module “gen_hwjpeg_version”: mo
dule source path “hardware/rockchip/libhwjpeg/.git/HEAD” does not exist
修改报错的路径下的文件，将.git相关内容删除后重新编译

4.创建过滤文件

查看源码新增内容
git status

gedit .gitignore
输入以下内容
/out
rockdev

注：/out加/表示只忽略当前目录下的out目录

5.再次提交

git status
显示只剩下添加的.gitignore文件
git add -f .
git commit -am “增加.gitignore过滤文件”
