将LiteOs-m操作系统迁移到RISCV架构的芯片上（HX280049），完成软件中断和定时器中断配置后，同时创建两个任务：LiteOs_1，LiteOs_2，开始调度后，会进入ASSERT；

LiteOs_1优先级为2，90个tick执行一次；LiteOs_2优先级为1，100个tick执行一次；

    (VOID)memset((void *)(&task_init_param1), 0, sizeof(TSK_INIT_PARAM_S));
    task_init_param1.usTaskPrio = 2; /* 任务优先级，数值越小，优先级越高*/
    task_init_param1.pcName = "LiteOs_2";/* 任务名称 */
    task_init_param1.pfnTaskEntry = (TSK_ENTRY_FUNC)liteOsTask2;
    task_init_param1.uwStackSize = LOSCFG_BASE_CORE_TSK_DEFAULT_STACK_SIZE;   /* 任务栈大小 */

    uwRet = LOS_TaskCreate(&Test2_Task_Handle, &task_init_param1);
    if(uwRet != LOS_OK){
    	printf("Create Task LiteOS 2 Failed!\r\n");
    }

    TSK_INIT_PARAM_S task_init_param2; /*定义一个局部变量 */
    (VOID)memset((void *)(&task_init_param2), 0, sizeof(TSK_INIT_PARAM_S));
    task_init_param2.usTaskPrio = 1; /* 任务优先级，数值越小，优先级越高*/
    task_init_param2.pcName = "LiteOs_1";/* 任务名称 */
    task_init_param2.pfnTaskEntry = (TSK_ENTRY_FUNC)liteOsTask1;
    task_init_param2.uwStackSize = LOSCFG_BASE_CORE_TSK_DEFAULT_STACK_SIZE;   /* 任务栈大小 */

    uwRet = LOS_TaskCreate(&Test1_Task_Handle, &task_init_param2);
	if(uwRet != LOS_OK){
		printf("Create Task LiteOS 1 Failed!\r\n");
	}

由于HX280049的定时器是32位，而LiteOs-m默认64位，就将LiteOs的UINT64全部改为32；

typedef unsigned long     UINT64;
typedef signed long       INT64;
//typedef unsigned long long     UINT64;
//typedef signed long long       INT64;

首先进入Swt_Task，之后进入LiteOs_1，之后LiteOs_2，之后IdleCore000，最后LiteOs_1任务，然后直接进入ASSERT；
