手把手教你移植openharmony3.0到stm32（liteos_m）

stm32系列芯片移植openhrmony3.0 liteos_m

之前找了很多文章，但是由于本身这方面文章较少加上官网文档太过简洁，移植过程比较繁琐，特此纪录。

附上最终模板地址:https://gitee.com/emb-y/hm3-to-stm32

一、创建stm32cubemx模板工程

为了方便移植先使用stm32cubemx生成模板工程， 以stm32f411为例

当然要用嵌软人的helloworld–点灯来证明是否移植成功
这块核心板的led在pc13，直接用cubemx生成一个模板程序

这里只初始化pc13为Output

只需要设置一个名字以及把工具链设置为MakeFile，然后点击生成即可。
工程目录如下：

二、添加鸿蒙需要的配置文件以及修改MakeFile

该处参考连志安老师的帖子和鸿蒙官方文档

添加build.sh文件到根目录

set -e

按照鸿蒙官方的要求规范目录结构
修改stm32cubemx项目名为stm32f411core
规则为：
device/厂商名称/板卡名称

新建ventor文件夹
创建如下目录结构：

该文件为鸿蒙的编译选项配置，可参考鸿蒙官方文档

在BUILD.gn中写入：

在hdf.hcs中写入：

//#include "../../../../device/hisilicon/hispark_taurus/sdk_liteos/config/uart/uart_config.hcs"

#include "device_info/device_info.hcs"

root {
    module = "st,stm32_chip";
}

在device_info.hcs中写入：

 root {
    device_info {
        match_attr = "hdf_manager";
        template host {
            hostName = "";
            priority = 100;
            template device {
                template deviceNode {
                    policy = 0;
                    priority = 100;
                    preload = 0;
                    permission = 0664;
                    moduleName = "";
                    serviceName = "";
                    deviceMatchAttr = "";
                }
            }
        }
        platform :: host {
            hostName = "platform_host";
            priority = 50;
            device_uart :: device {
                device0 :: deviceNode {
                    policy = 1;
                    priority = 40;
                    permission = 0644;
                    moduleName = "HDF_PLATFORM_UART";
                    serviceName = "HDF_PLATFORM_UART_0";
                    deviceMatchAttr = "hisilicon_hi35xx_uart_0";
                }
            }
        }
    }
}

三、将自己写的工程文件移入鸿蒙源码

该处采用全量代码
此处略过鸿蒙hpm等配置（通过鸿蒙官网设备开发3.0的工具可以自动化配置）
下载arm-none-eabi-gcc、gn、ninja工具链并配置环境变量
并复制目录到鸿蒙源码对应目录

这时候激活鸿蒙官方的python虚拟环境（如果使用官方工具配置环境需要这一步）

source /opt/Huawei/DevEco-Device-Tool/core/deveco-venv/bin/activate

在源码更目录终端下输入hb set可以看到自己设置的开发板编译选项
回车选择后输入

hb build

即可开始编译

四、修改报错问题

如果不出会遇到报错
有两处错误可能是因为工作人员粗心

这里的PRINT_ERR少了一个参数，我直接补了个字符串。（这个问题现在开源社区已经修复了）
还有一处是也是输出报错，uint32_t类型打印时传的是%u，这个也可能是编译器问题

另一处我猜测是我编译配置有问题，但是这个地方为了省事我直接把一个编译选项屏蔽掉了

最后再此编译，令人激动的时刻到来了

在out目录下可以看到.bin文件

五、烧录验证

打开STM32 ST-Link Utility烧录到开发板

按下开发板rst键

可以看到led闪烁，移植成功！
