  大家好，我是极智视界，本教程具体记录了全志 XR806 OpenHarmony 鸿蒙零碎固件编译的办法。

  XR806 是全志科技旗下子公司广州芯之联研发设计的一款反对 WiFi 和 BLE 的高集成度无线 MCU 芯片，反对鸿蒙 L0 零碎。具备集成度高、硬件设计简略、BOM 成本低、安全可靠等长处。可宽泛满足 智能家居、智慧楼宇、工业互联、儿童玩具、电子比赛、极客DIY 等畛域的无线连接需要。上图：

     

     

  上面开始固件编译。

# 下载 repomkdir -p bincurl https://storage.googleapis.com/git-repo-downloads/repo > bin/repochmod a+rx bin/repoPATH="`pwd`/bin:$PATH"# 下载 hbpip install -i https://pypi.douban.com/simple --user ohos-buildPATH="$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

  这里须要留神一下，间接执行上述命令应该会报错fatal: Cannot get https://gerrit.googlesource.com/git-repo/clone.bundle，解决办法为批改清华源。有两种批改形式，如下：

   (1) 批改 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/'    # 批改为这个

   (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/

   持续：

repo sync -crepo forall -c 'git lfs pull'

  开始编译固件：

cd <xr806_openharmony_path>cd device/xradio/xr806/xr_skylarkcp project/demo/audio_demo/gcc/deconfig .configmake menuconfig

   生成图形化配置界面，间接 EXIT 退出即可。

make build_clean    # 革除旧配置 make lib -j         # 依据配置生成动态库和全局头文件

cd -hb set           # 抉择 wifi_skylark

  此时再按一下回车，抉择 wifi_shylark，而后再间接回车就行：

      

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_skylarkpython config.py

   官网提供的 config.py 有门路相干的 Bug，改成如下：

#!/usr/bin/python3import ospwd = os.path.dirname (__file__)f = open('{0}.config'.format(pwd),'r')                        # 门路改成这样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')   # 门路改成这样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，而后持续：

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干文件：

       

   其中 xr_system.img 就是前面咱们固件烧录须要用到的镜像文件。

   至此就实现了 XR806 OpenHarmony 的固件编译，心愿我的分享能对你的学习有一点帮忙。
