移植华为LiteOS

1. 安装STM32CubeMX

构建裸机工程，生成MDK-ARM V5 的工程

2.拷贝 LiteOS 内核源码及测试相关代码

拷贝arch, demos, kernel目录拷贝到middlewares/liteos中
在Keil工程中添加.c 源文件，以及设置头文件路径

raw-project-include-path-keil.1e569edf.png raw-project-group-kernel.32aa4518.png

3.拷贝OS_CONFIG 目录

添加头文件路径。

4. PendSV_Handler 和 SysTick_Handler 这两个函数

屏蔽
如果#define LOSCFG_PLATFORM_HWI YES
则不用屏蔽SysTick_Handler

5.使用los_startup_keil.s代替startup_stm32l476xx.s

修改sct文件配置内存

6.测试中断

void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
  /* Prevent unused argument(s) compilation warning */
  UNUSED(GPIO_Pin);
    dprintf("\r\n User IRQ test!!!\r\n");
  /* NOTE: This function Should not be modified, when the callback is needed,
           the HAL_GPIO_EXTI_Callback could be implemented in the user file
   */
}
static VOID User_IRQHandler(VOID)
{

//    LOS_InspectStatusSetByID(LOS_INSPECT_INTERRUPT,LOS_INSPECT_STU_SUCCESS);
 HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_13);
    return;
}

UINT32 Example_Interrupt(VOID)
{
    dprintf("\r\n Example_Interrupt\r\n");
    UINTPTR uvIntSave;
    uvIntSave = LOS_IntLock();

    Example_Exti0_Init();

    LOS_HwiCreate(40, 0, 0, User_IRQHandler, 0);//create interrupt

    LOS_IntRestore(uvIntSave);

    return LOS_OK;
}
