大家好，我是极智视界，本教程详细记录了全志 XR806 OpenHarmony 鸿蒙系统固件编译的方法。
XR806 是全志科技旗下子公司广州芯之联研发设计的一款支持 WiFi 和 BLE 的高集成度无线 MCU 芯片，支持鸿蒙 L0 系统。具有集成度高、硬件设计简单、BOM 成本低、安全可靠等优点。可广泛满足 智能家居、智慧楼宇、工业互联、儿童玩具、电子竞赛、极客DIY 等领域的无线连接需求。上图：
下面开始固件编译。
# 下载 repo mkdir -p bin curl https://storage.googleapis.com/git-repo-downloads/repo > bin/repo chmod a+rx bin/repo PATH="`pwd`/bin:$PATH" # 下载 hb pip install -i https://pypi.douban.com/simple --user ohos-build PATH="$HOME/.local/bin:$PATH" # 下载 openharmony 源码 repo init -u ssh://git@gitee.com/openharmony-sig/manifest.git -b OpenHarmony_1.0.1_release --no-repo-verify -m devboard_xr806.xml
这里需要注意一下，直接执行上述命令应该会报错 fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle，解决方法为修改清华源。有两种修改方式，如下：
(1) 修改 bin/repo 中的 REPO_URL
REPO_URL = os.environ.get('REPO_URL', None) if not REPO_URL: # REPO_URL = 'http://gerrit.googlesource.com/git-repo' REPO_URL = 'http://mirrors.tuna.tsinghua.edu.cn/git/git-repo/' # 修改为这个
(2) 在执行命令后指令 --repo-url=http://mirrors.tuna.tsinghua.edu.cn/git/git-repo/，也即：
repo init -u ssh://git@gitee.com/openharmony-sig/manifest.git -b OpenHarmony_1.0.1_release --no-repo-verify -m devboard_xr806.xml --repo-url=http://mirrors.tuna.tsinghua.edu.cn/git/git-repo/
继续：
repo sync -c repo forall -c 'git lfs pull'
# 下载 arm toolchain wget -c https://developer.arm.com/-/media/Files/downloads/gnu-rm/10-2020q4/gcc-arm-none-eabi-10-2020-q4-major-x86_64-linux.tar.bz2 tar -xf gcc-arm-none-eabi-10-2020-q4-major-x86_64-linux.tar.bz2 # 创建 ~/tools 目录 mkdir ~/tools cp -r ./gcc-arm-none-eabi-10-2020-q4-major ~/tools # 更新 toolchain cd <xr806_openharmony_path> sed -i "s@~/tools/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-@`pwd`/gcc-arm-none-eabi-10-2020-q4-major/bin/arm-none-eabi-@g" ./device/xradio/xr806/liteos_m/config.gni sed -i "s@~/tools/gcc-arm-none-eabi-10-2020-q4-major/bin@`pwd`/gcc-arm-none-eabi-10-2020-q4-major/bin@g" ./device/xradio/xr806/xr_skylark/gcc.mk # 修正 SDKconfig.gni sed -i "s@open('\.{0}/@open('{0}/@g" ./device/xradio/xr806/xr_skylark/config.py sed -i "s@open('\.{0}/@open('{0}/@g" ./device/xradio/xr806/libcopy.py
开始编译固件：
cd <xr806_openharmony_path> cd device/xradio/xr806/xr_skylark cp project/demo/audio_demo/gcc/deconfig .config make menuconfig
生成图形化配置界面，直接 EXIT 退出即可。
make build_clean # 清除旧配置 make lib -j # 根据配置生成静态库和全局头文件
cd - hb set # 选择 wifi_skylark
此时再按一下回车，选择 wifi_shylark，然后再直接回车就行：
hb build -f # 开始编译
报错 Unable to load SDKconfig.gni
解决办法：
cd <xr806_openharmony_path> cd device/xradio/xr806/xr_skylark python config.py
官方提供的 config.py 有路径相关的 Bug，改成如下：
#!/usr/bin/python3 import os pwd = os.path.dirname (__file__) f = open('{0}.config'.format(pwd),'r') # 路径改成这样 DATA = ['#XR806 config'] for line in f.readlines(): if line[0] != '#' and line[0] != '\n': line = line.strip('\n') DATA.append(line) GNf = open('{0}../liteos_m/SDKconfig.gni'.format(pwd),'w') # 路径改成这样 GNf.write('#Build by config.py DO NOT EDIT!\n\n') GNf.write('SDK_cflags = [\n\ "-mcpu=cortex-m33",\n\ "-mtune=cortex-m33",\n\ "-march=armv8-m.main+dsp",\n\ "-mfpu=fpv5-sp-d16",\n\ "-mfloat-abi=softfp",\n\ "-mcmse",\n\ "-mthumb",\n\ "-c",\n\ "-g",\n\ "-fno-common",\n\ "-fmessage-length=0",\n\ "-fno-exceptions",\n\ "-ffunction-sections",\n\ "-fdata-sections",\n\ "-fomit-frame-pointer",\n\ "-Wall",\n\ #"-Werror",\n\ "-Wno-cpp",\n\ "-Wpointer-arith",\n\ "-Wno-error=unused-function",\n\ "-MMD",\n\ "-MP",\n\ "-Os",\n\ "-DNDEBUG",\n\ "-Wno-error=stringop-truncation",\n\ "-Wno-error=restrict",\n\ "-includexr_config.h",\n\ "-includecommon/prj_conf_opt.h",\n\ "-DCONFIG_CHIP_ARCH_VER=3",\n\ "-DCONFIG_ARCH_APP_CORE",\n\ "-DCONFIG_CPU_CM33F",\n\ ]\n\n') PROJECT = [x for i,x in enumerate(DATA) if x.find('CONFIG_PROJECT=') != -1] if len(PROJECT) == 1: ProjectPath = PROJECT[0] ProjectPath = ProjectPath.strip('CONFIG_PROJECT=') GNf.write('ProjectPath = {0}\n\n'.format(ProjectPath)) if ProjectPath == '"bootloader"' or ProjectPath == '"test/etf"': GNf.write('declare_args() {IsBootloader = "true"}\n') else: GNf.write('declare_args() {IsBootloader = "false"}\n') #print (DATA)
完了会在 <xr806_openharmony_path>/device/xradio/xr806/liteos_m 目录下生成 SDKconfig.gni，然后继续：
cd - hb build -f
完了会在 <xr806_openharmony_path>/device/xradio/xr806/xr_skylark/out 下生成编译好的固件镜像相关文件：
其中 xr_system.img 就是后面我们固件烧录需要用到的镜像文件。
至此就完成了 XR806 OpenHarmony 的固件编译，希望我的分享能对你的学习有一点帮助。
