记录一下移植openharmony到STM32H743IIT6的过程

• 一、用STM32CubeMX生成一个makefile的工程
• 二、搭建系统环境
• 三、用vscode连接虚拟机
• 四、下载openharmony3.0源码
• 五、移植准备
• • 目录规范
  • 板级 *device* 配置
  • • 编译工具链和编译选项配置
    • 编译脚本配置
    • Makefile配置
    • build.sh配置
    • 内核特性配置项 target_config.h
    • main函数
  • 产品级 *vendor* 配置
  • • config.json配置
    • 编译脚本配置
• 六、开始移植

一、用STM32CubeMX生成一个makefile的工程

选择第一个创建工程

选择对应的芯片，这里我用的是stm32h743的野火的开发板

移植现象以点亮led为例，选择点亮led的引脚为输出模式，其他默认

这一步看个人习惯吧，默认不管也可以

选择工具链为makefile，如果对时钟有需求可以在Clock Configuration选项修改，我这里直接默认生成了

二、搭建系统环境

要用虚拟机ubuntu编译，具体配置命令可以参考华为官方教程： https://device.harmonyos.com/cn/docs/documentation/guide/quickstart-lite-package-environment-0000001105407498.
（20.04版本有很多bug，安装工具时会提示各种依赖，就很烦，而且我个人也解决不了，所以就改用的18版本）
18版本下载地址
因为鸿蒙源码比较大，安装ubuntu时虚拟硬盘最好搞大点，我这里直接给了100G
如果安装的过程中提示没有某个工具，那就按照ubuntu的提示安装就好了，类似：

安装hb需要python3.8以上版本，我的3.6会提示这个错误：

安装python3.8：

sudo apt install python3.8

python3.8 --version #检验是否安装成功

python3.8 -m pip install --user ohos-build #把上面的python3改成python3.8

实际上最主要的目的就是安装hb，安装好后执行hb -h命令，如出现以下信息则安装成功：

20版本的话会提示各种依赖的问题，如果解决不了就换18版本吧。除了会提示工具缺少需要安装外，应该就没有其他问题了

三、用vscode连接虚拟机

为了方便代码编写，直接在主机端用vscode连接虚拟机，怎么连接的可以参考：
vscode使用ssh连接远程Ubuntu服务器

四、下载openharmony3.0源码

可以按官方的教程用git下载，也可以直接从镜像站点下载，看个人喜好了。
我是从镜像站点下载的。
1、官方教程git下载
2、镜像站点下载

下好源码后通过共享文件放到ubuntu里面，或者你直接在ubuntu里面下也行。
注意先别解压
将源码压缩包复制到新建的openharmony目录下后再解压

cp code-v3.0-LTS.tar.gz ~/openharmony

tar -zxvf code-v3.0-LTS.tar.gz #在~/openharmony目录下解压

这里推荐用FileZilla软件：下载地址

连接后就可以在Windows和ubuntu之间方便快捷的传输文件了

再用vscode连接虚拟机后，就可以打开源码目录了：

子目录代表的含义：

五、移植准备

注：参考了华为官方文档内容，如果对细节部分更感兴趣可以直接去看官方文档：https://device.harmonyos.com/cn/docs/documentation/guide/porting-chip-prepare-knows-0000001064030766

目录规范

HarmonyOS整体工程较为复杂，我们只是简单的移植，不涉及复杂的特性增强，只需要重点关注如下目录即可：

目录名称	描述
/build/lite	HarmonyOS基础编译构建框架
/kernel/liteos_m	基础内核，其中芯片架构相关实现在arch目录下
/device	板级相关实现，各个三方厂商按照HarmonyOS规范适配实现
/vendor	产品级相关实现，主要由华为或者产品厂商贡献

其中我们要配置的就是device和vendor目录
目录结构和具体描述如下：

根据上述目录规范要求规范文件夹：

device/厂商名称/单板名
vendor/厂商名称/单板名

把第一步stm32cubemx生成的工程文件全部放到 /device/st/stm32h743_harmony 里，顺便把vendor的目录也创建好

板级 device 配置

编译工具链和编译选项配置

在代码根目录 /device/st/stm32h743_harmony 里新建 liteos_m 文件夹并添加 config.gni文件：

# Kernel type, e.g. "linux", "liteos_a", "liteos_m".（ 开发板使用的内核类型）
kernel_type = "liteos_m" 

# Kernel version.（开发使用的内核版本）
kernel_version = "3.0.0"

# Board CPU type, e.g. "cortex-a7", "riscv32".（开发板CPU类型）
board_cpu = "cortex-m7"

# Board arch, e.g.  "armv7-a", "rv32imac".（开发芯片arch）
board_arch = ""

# Toolchain name used for system compiling.
# E.g. gcc-arm-none-eabi, arm-linux-harmonyeabi-gcc, ohos-clang,  riscv32-unknown-elf.
# Note: The default toolchain is "ohos-clang". It's not mandatory if you use the default toochain.
#（开发板自定义的编译工具链名称）
board_toolchain = "arm-none-eabi-gcc"

# The toolchain path instatlled, it's not mandatory if you have added toolchian path to your ~/.bashrc.
#（编译工具链路径）
board_toolchain_path = ""

# Compiler prefix.（编译工具链前缀）
board_toolchain_prefix = "arm-none-eabi-"

# Compiler type, "gcc" or "clang".（编译工具链类型）
board_toolchain_type = "gcc"

# Board related common compile flags.（开发板配置的c文件编译选项）
board_cflags = [
  "-mcpu=cortex-m7",
  "-mfpu=fpv5-d16",
  "-mfloat-abi=soft",
  "-mthumb",
  "-Og",
  "-Wall",
  "-fdata-sections",
  "-ffunction-sections",
  "-DUSE_HAL_DRIVER", #看情况修改 （Makefile里C_DEFS的配置）
  "-DSTM32H743xx", #看情况修改
]

#（开发板配置的cpp文件编译选项）
board_cxx_flags = board_cflags

#（开发板配置的链接选项）
board_ld_flags = []

# Board related headfiles search path.（头文件路径）
board_include_dirs = [
  "//kernel/liteos_m/kernel/arch/arm/cortex-m7/gcc",
  "//device/st/stm32h743",
  "//device/st/stm32h743/Core/Inc",
  "//device/st/stm32h743/Drivers/CMSIS/Include",
  "//device/st/stm32h743/Drivers/CMSIS/Device/ST/STM32H7xx/Include",
  "//device/st/stm32h743/Drivers/STM32H7xx_HAL_Driver/Inc",
    "//device/hisilicon/hispark_pegasus/hi3861_adapter/kal/cmsis",
]

# Board adapter dir for OHOS components.
board_adapter_dir = ""

# Sysroot path.
board_configed_sysroot = ""

# Board storage type, it used for file system generation.
storage_type = ""

编译脚本配置

新增的开发板，对应目录下需要新增BUILD.gn文件作为开发板编译的总入口
首先是根目录下的BUILD.gn：

import("//build/lite/config/component/lite_component.gni")

group("stm32h743_harmony") {
}

build_ext_component("stm32h743_harmony_ninjia") {
  exec_path = rebase_path(".", root_build_dir)
  outdir = rebase_path("$root_out_dir")

  if (board_toolchain_path != "") {
    toolchain_path = rebase_path("$board_toolchain_path")
    command = "./build.sh ${outdir} ${toolchain_path}"
  } else {
    command = "./build.sh ${outdir}"
  }
  deps = [ "//build/lite:ohos" ]
}

static_library("startup_stm32h743xx") {
  sources = [ "startup_stm32h743xx.s" ]

  include_dirs = [ "." ]

  deps = [  
    "//device/st/stm32h743_harmony/Core:core",
    "//device/st/stm32h743_harmony/Drivers/STM32H7xx_HAL_Driver:STM32H7xx_HAL_Driver",
  ]
}

group直接写文件夹名
build_ext_component自定义，但是要与Makefile文件里有效代码第一行TARGET一致
sources 为stm32cubemx生成的.s文件的名称
deps 为下级gn文件列表

接着是Drivers\STM32H7xx_HAL_Driver下的BUILD.gn:

static_library("STM32H7xx_HAL_Driver") {
  sources = [
    "Src/stm32h7xx_hal_cortex.c",
    "Src/stm32h7xx_hal_dma_ex.c",
    "Src/stm32h7xx_hal_dma.c",
    "Src/stm32h7xx_hal_exti.c",
    "Src/stm32h7xx_hal_flash.c",
    "Src/stm32h7xx_hal_flash_ex.c",
    "Src/stm32h7xx_hal_gpio.c",
    "Src/stm32h7xx_hal_hsem.c",
    "Src/stm32h7xx_hal_i2c_ex.c",
    "Src/stm32h7xx_hal_i2c.c",
    "Src/stm32h7xx_hal_mdma.c",
    "Src/stm32h7xx_hal_pwr_ex.c",
    "Src/stm32h7xx_hal_pwr.c",
    "Src/stm32h7xx_hal_rcc_ex.c",
    "Src/stm32h7xx_hal_rcc.c",
    "Src/stm32h7xx_hal_tim_ex.c",
    "Src/stm32h7xx_hal_tim.c",
    "Src/stm32h7xx_hal.c",
  ]

  include_dirs = [
    "Inc",
    "Inc/Legacy",
    "../CMSIS/Include",
    "../CMSIS/Device/ST/STM32H7xx/Include",
    "../../Core/Inc",
  ]

}

sources 为此目录下的.c文件
include_dirs为头文件路径

最后是 \Core 下的BUILD.gn:

static_library("core") {
  sources = [
    "Src/main.c",
    "Src/gpio.c",
    "Src/stm32h7xx_hal_msp.c",
    "Src/stm32h7xx_it.c",
    "Src/system_stm32h7xx.c",  
  ]

  include_dirs = [
    "Inc",
    "../",
    "../Drivers/STM32H7xx_HAL_Driver/Inc",
    "../Drivers/STM32H7xx_HAL_Driver/Inc/Legacy",
    "../Drivers/CMSIS/Include",
    "../Drivers/CMSIS/Device/ST/STM32H7xx/Include",
    "//kernel/liteos_m/kernel/include",
    "//kernel/liteos_m/utils",
    "//kernel/liteos_m/kal/cmsis",
    "//kernel/liteos_m/kernel/arch/include",
  ]
}

同理，sources 为此目录下的.c文件
include_dirs为头文件路径
总共3个gn

#!/bin/bash

set -e

OUT_DIR="$1"
TOOLCHAIN_DIR="$2"


function main(){
    ROOT_DIR=$(cd $(dirname "$0");pwd)
    if [ -z "${TOOLCHAIN_DIR}" ]; then

内核特性配置项 target_config.h

liteos_m的完整配置能力及默认配置在los_config.h定义，该头文件中的配置项可以根据不同的单板进行裁剪配置。
要进行不同的板级配置，则可将对应的配置项直接定义到对应单板的device/xxxx/target_config.h文件中，其他未定义的配置项，采用los_config.h中的默认值。
在代码根目录下创建 target_config.h 文件

产品级 vendor 配置

config.json配置

在 \vendor\st\stm32h743_harmony 下新建 config.json

{
    "product_name": "stm32h743_harmony",     //产品名称，支持自定义，建议与vendor下的三级目录名称一致
    "ohos_version": "OpenHarmony 3.0",       //HarmonyOS版本号
    "device_company": "st",                  //芯片解决方案厂商名称，建议与device的二级目录名称一致
    "board": "stm32h743_harmony",            //开发板名称，建议与device的三级级目录名称一致
    "kernel_type": "liteos_m",               //内核类型，应与开发板支持的内核类型匹配
    "kernel_version": "3.0.0",               //内核版本号，应与开发板支持的内核版本匹配

          }

}

编译脚本配置

在 \vendor\st\stm32h743_harmony 下新建 BUILD.gn

group("stm32h743_harmony") {
}

六、开始移植

将配置好的目录移植到鸿蒙源码对应的目录，
即device里的st文件夹移到鸿蒙device目录里，
vendor里的st文件夹移植到鸿蒙vendor目录里

点击“+”新建终端，再用cd命令进入到源码目录

输入 hb set

选择st下的stm32h743_harmony后回车，再输入hb build -f 命令编译
不出意外会报错：

这是官方源码漏了一个字符串，直接进入对应目录，对应行号添加一下：

只改这一个，再编译后，我这里又出现新的问题：
鸿蒙这玩意就是坑多，而且不允许有一个警告，有就编译不通过。
明明有这个头文件却识别不出来，后续改了其他地方，报的错又不一样了，感觉还是脚本和makefile那里没写好，毕竟我也是参考的别人的。
等博主makefile学精了以后再来尝试吧，本贴就给各位借鉴一下。如有大佬指点就更好了。
另外如果正常编译通过的话会显示编译seccess，然后再把OUT目录下的hex文件烧录到板子上就算成功了。
