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 该处参考连志安老师的帖子和鸿蒙官方文档 添加target_config.h到项目根目录 #ifndef _TARGET_CONFIG_H #define _TARGET_CONFIG_H #include "stm32f4xx.h" #ifdef __cplusplus #if __cplusplus extern "C" { #endif /* __cplusplus */ #endif /* __cplusplus */ /*============================================================================= System clock module configuration =============================================================================*/ #define OS_SYS_CLOCK SystemCoreClock #define LOSCFG_BASE_CORE_TICK_PER_SECOND (1000UL) #define LOSCFG_BASE_CORE_TICK_HW_TIME 0 #define LOSCFG_BASE_CORE_TICK_WTIMER 0 #define LOSCFG_BASE_CORE_TICK_RESPONSE_MAX SysTick_LOAD_RELOAD_Msk /*============================================================================= Hardware interrupt module configuration =============================================================================*/ #define LOSCFG_PLATFORM_HWI 1 #define LOSCFG_USE_SYSTEM_DEFINED_INTERRUPT 1 #define LOSCFG_PLATFORM_HWI_LIMIT 128 /*============================================================================= Task module configuration =============================================================================*/ #define LOSCFG_BASE_CORE_TSK_LIMIT 24 #define LOSCFG_BASE_CORE_TSK_IDLE_STACK_SIZE (0x500U) #define LOSCFG_BASE_CORE_TSK_DEFAULT_STACK_SIZE (0x2D0U) #define LOSCFG_BASE_CORE_TSK_MIN_STACK_SIZE (0x130U) #define LOSCFG_BASE_CORE_TIMESLICE 1 #define LOSCFG_BASE_CORE_TIMESLICE_TIMEOUT 20000 /*============================================================================= Semaphore module configuration =============================================================================*/ #define LOSCFG_BASE_IPC_SEM 1 #define LOSCFG_BASE_IPC_SEM_LIMIT 48 /*============================================================================= Mutex module configuration =============================================================================*/ #define LOSCFG_BASE_IPC_MUX 1 #define LOSCFG_BASE_IPC_MUX_LIMIT 24 /*============================================================================= Queue module configuration =============================================================================*/ #define LOSCFG_BASE_IPC_QUEUE 1 #define LOSCFG_BASE_IPC_QUEUE_LIMIT 24 /*============================================================================= Software timer module configuration =============================================================================*/ #define LOSCFG_BASE_CORE_SWTMR 1 #define LOSCFG_BASE_CORE_SWTMR_ALIGN 0 #define LOSCFG_BASE_CORE_SWTMR_LIMIT 48 /*============================================================================= Memory module configuration =============================================================================*/ #define LOSCFG_MEM_MUL_POOL 1 #define OS_SYS_MEM_NUM 20 /*============================================================================= Exception module configuration =============================================================================*/ #define LOSCFG_PLATFORM_EXC 1 /* ============================================================================= printf module configuration ============================================================================= */ #define LOSCFG_KERNEL_PRINTF 1 #define LOSCFG_BASE_CORE_SCHED_SLEEP 1 #define LOSCFG_SYS_HEAP_SIZE 0x4000UL #ifdef __cplusplus #if __cplusplus } #endif /* __cplusplus */ #endif /* __cplusplus */ #endif /* _TARGET_CONFIG_H */该文件为liteos_m的配置文件 添加build.sh文件到根目录 #!/bin/bash set -e OUT_DIR="$1" TOOLCHAIN_DIR="$2" function main(){ ROOT_DIR=$(cd $(dirname "$0");pwd) if [ -z "${TOOLCHAIN_DIR}" ]; then make clean && make -j16 OUT_DIR_PATH=${OUT_DIR} else make clean && make -j16 OUT_DIR_PATH=${OUT_DIR} TOOLCHAIN_DIR_PATH=${TOOLCHAIN_DIR} fi } main "$@"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 # Kernel type, e.g. "linux", "liteos_a", "liteos_m". kernel_type = "liteos_m" # Kernel version. kernel_version = "3.0.0" # Board CPU type, e.g. "cortex-a7", "riscv32". board_cpu = "cortex-m4" # Board arch, e.g. "armv7-a", "rv32imac". 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".

*/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。 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： 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 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 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 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 打开STM32 ST-Link Utility烧录到开发板 |
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： 
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
在config.json文件中写入：
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）
回车选择后输入
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
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 
按下开发板rst键 
可以看到led闪烁，移植成功！【本文地址】
