编译
以DAYU200(RK3568)为例
./build.sh --product-name rk3568 --ccache --no-prebuilt-sdk
烧录系统
以DAYU200(RK3568)为例,其编译生成的镜像文件在下面位置,需要将其拷贝到window系统然后使用RK提供的RKDevTool进行烧录

调试命令
hdc命令
hdc（Harmony Device Connector）是Openharmony标准的设备连接与调试工具，功能类似于 Android 的 adb。它用于开发过程中与设备（或模拟器）进行通信，包括文件传输、应用安装、日志查看、命令执行等

hdc -t 192.168.1.100:8710 shell
通过网络链接调试设备,行当于adb connect & adb shell
hilog
hilog 是 OpenHarmony 中用于日志系统的命令行工具，类似于 Android 的 logcat。它可以帮助开发者在调试过程中查看系统运行日志、定位问题，是系统调试的重要工具之一
hilog -x
格式化日志输出，更易读
#过滤日志级别,常用级别debug,info,warn,error,fatal,
hilog -x -L error
#or
hilog -x -L E # Error#过滤特定 tag 标签
hilog -x -T mytag#过滤多个 tag
hilog -x -T tag1 -T tag2#保存日志到文件
hilog -x > /data/logs/hilog.txt#清除日志缓存
hilog -c
