  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://[email protected]/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://[email protected]/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。
