开发板使用大禹系列｜HH-SCDAYU200开发套件（Quad-core Cortex-A55 up to 2.0GHz）。
在宿主机环境上可能会遇到各种各样的问题，可以使用 docker 编译, 以ubuntu22.04为例，说明环境的搭建。
# 获取代码环境
apt-get update -y && apt-get install python3 python3-pip -y
apt-get install git git-lfs -y
mkdir -p ~/.local/bin/
curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /home/sonvhi/chenxiaosong/sw/repo
chmod a+x ~/.local/bin/repo
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests
ln -s /usr/bin/python3 /usr/bin/python
# 编译环境
apt-get update && apt-get install binutils git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3 python3-pip ruby libtinfo-dev libtinfo5 -y
apt install file -y
apt-get install default-jdk -y # 如果报错: javac: command not found
apt install libelf-dev -y # error: Cannot resolve BTF IDs for CONFIG_DEBUG_INFO_BTF
apt-get install libssl-dev -y # scripts/extract-cert.c:21:10: fatal error: 'openssl/bio.h' file not found
apt install liblz4-tool -y # /bin/sh: 1: lz4c: not found
apt-get install genext2fs -y # make-boot.sh: line 22: genext2fs: command not found
apt-get install cpio -y
# 头文件找不到解决方法
apt install apt-file -y
apt-file search X11/Xcursor/Xcursor.h # libxcursor-dev: /usr/include/X11/Xcursor/Xcursor.h
apt-file search X11/extensions/Xrandr.h # libxrandr-dev: /usr/include/X11/extensions/Xrandr.h
apt-file search X11/extensions/Xinerama.h # libxinerama-dev: /usr/include/X11/extensions/Xinerama.h
apt install libxcursor-dev libxrandr-dev libxinerama-dev -y还可以参考openharmony获取源码
执行以下命令获取代码:
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify && repo sync -c && repo forall -c 'git lfs pull' && bash build/prebuilts_download.sh编译命令如下:
# 镜像输出在 out/rk3568/packages/phone/images 目录下
# 32位
./build.sh --product-name rk3568 --ccache
./build.sh --product-name rk3568 --ccache --fast-rebuild # --fast-rebuild 增量编译时跳过一些已经完成的步骤
./build.sh --product-name rk3568 --ccache --build-target dfs_service --fast-rebuild
# 64位
./build.sh --product-name rk3568 --ccache --target-cpu arm64
./build.sh --product-name rk3568 --ccache --target-cpu arm64 --fast-rebuild # 增量编译时跳过一些已经完成的步骤
./build.sh --product-name rk3568 --ccache --target-cpu arm64 --build-target dfs_service --fast-rebuild # --build-target dfs_service 只编译某个servicelinux上压缩image文件:
zip -jr images.zip out/rk3568/packages/phone/images/特别需要注意的是: 软件路径中不要含有中文，尤其是对英文版的windows系统。
windows安装DriverAssitant_v5.1.1\DriverInstall.exe后，打开RKDevTool.exe， 配置以下路径:
0x00000000 Loader MiniLoaderAll.bin
0x00000000 Parameter parameter.txt
0x00002000 Uboot uboot.img
0x00006000 resource resource.img
0x00004000 misc 可不选
0x00009000 Boot_linux boot_linux.img
0x00039000 ramdisk ramdisk.img
0x0003B000 System system.img
0x0043B000 Vendor vendor.img
0x0063B000 sys-prod 可不选
0x00654000 chip-prod 可不选
0x0066D000 updater updater.img
0x00677000 Userdata userdata.img配置重新导出为文件config.cfg。
winodws usb线连接rk3568板子上的usb3.0 OTG，在rk3568板子上按reset键，再长按vol+/recovery键，进入loader模式，点击RKDevTool工具上的执行按钮。可以只烧录System和Userdata（包含数据库）。
复制so文件的脚本scp_dfs_service_so.bat:
scp -r -P 55555 sonvhi@chenxiaosong.com:/home/sonvhi/chenxiaosong/code/openharmony/openharmony/out/rk3568/filemanagement/dfs_service/ .
@pause传输so文件到板子上的脚本push_dfs_service_so.bat:
hdc shell mount -o rw,remount /
hdc file send .\dfs_service\libcloud_adapter.z.so /system/lib/
hdc file send .\dfs_service\libcloud_daemon_kit_inner.z.so /system/lib/
hdc file send .\dfs_service\libcloudfiledaemon.z.so /system/lib/

hdc file send .\dfs_service\libdistributedfiledentry.z.so /system/lib/
hdc file send .\dfs_service\libdistributedfileutils.z.so /system/lib/
hdc shell sync
hdc shell reboot
@pausehdc工具从每日构建中搜索ohos-sdk。
hdc shell usb线连接rk3568板子上的usb3.0 OTG，注意不是DEBUG串口。
如果始终无法连接，win+r，输入regedit回车，找到注册表 计算机\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{88bae032-5a81-49f0-bc3d-a4ff138216d6}，确认是否有Upperfilters和Lowerfilters，删除后重新插拔。

mount -o rw,remount / # 重新可读可写挂载
echo "SELINUX=permissive" > /etc/selinux/config # 重启后生效，默认是 SELINUX=enforcing
setenforce 0
