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

该文件为liteos_m的配置文件
添加build.sh文件到根目录

该文件为编译脚本
在根目录下新建liteos_m文件夹并添加config.gni文件

该例程采用cmsis,就是最简单的创建了一个任务,在任务中让灯闪烁。
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:
在config.json文件中写入:
{
"product_name": "stm32f411core",
"ohos_version": "OpenHarmony 1.0",
"device_company": "st",
"board": "stm32f411core",
"kernel_type": "liteos_m",
"kernel_version": "3.0.0",
"subsystems": [
{
"subsystem": "kernel",
"components": [
{ "component": "liteos_m",
"features":[
"enable_ohos_kernel_liteos_m_fs = false",
"enable_ohos_kernel_liteos_m_kal = false"
]
}
]
}
],
"vendor_adapter_dir": "//device/st/stm32f411core",
"third_party_dir": "//third_party",
"product_adapter_dir": "",
"ohos_product_type":"",
"ohos_manufacture":"",
"ohos_brand":"",
"ohos_market_name":"",
"ohos_product_series":"",
"ohos_product_model":"",
"ohos_software_model":"",
"ohos_hardware_model":"",
"ohos_hardware_profile":"",
"ohos_serial":"",
"ohos_bootloader_version":"",
"ohos_secure_patch_level":"",
"ohos_abi_list":""
}
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:
group("gd32f303_qidian") {
}
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!
