+TSK_INIT_PARAM_S 结构体添加stackAddr 字段
+
+* 涉及接口修改：

+    同步LOS_HwiDelete接口入参，新增HWI_IRQ_PARAM_S *irqParam参数，为后续共享中断功能的添加预留
+
+* 新增接口：
+LOS_TaskResRecycle
+LOS_CurrNanosec
+LOS_MDelay
+
+接口修改：
+LOS_QueueCreate：第一个入参添加const修饰并增加一种异常情况处理
+los_memory.c中 OS_ERROR 修改为LOS_NOK，重定义LOS_NOK为（UINT32）-1。
+
+接口位置转移：
+LOS_UDelay 由los_task.h/.c 转移到los_tick.h/.c 
+
+宏修改：
+LOS_ERRNO_MUX_PEND_INTERR 改名为 LOS_ERRNO_MUX_IN_INTERR

+
+* **posix:** 接口修改：

+    WEAK UINT64 HalGetTickCycle(UINT32 *period);
+    WEAK VOID HalTickLock(VOID);
+    WEAK VOID HalTickUnlock(VOID);
+  用户如果需要启用自己的tick timer需要自己实现相关接口(强属性)，在 "内核初始化之前" 通过调用：
+  LOS_TickTimerRegister 接口替换系统默认提供的tick timer相关接口。
+  无论用户提供的tick timer 还是系统默认提供的，均在内核初始化时启动。
+*   int pthread_key_create(pthread_key_t *k, void (*dtor)(void *))
+  int pthread_key_delete(pthread_key_t k)
+  int pthread_setspecific(pthread_key_t k, const void *x)
+  void *pthread_getspecific(pthread_key_t k)
+* 1.修改arch/include下接口，以ArchXX命名函数
+2.提取公共函数声明:ArchAtomicXchg32bits、ArchAtomicDecRet、ArchAtomicCmpXchg32bits
+3.新增部分原子操作c内联实现
+* 增加低内存资源回收注册相关接口LOS_LmkOpsNodeRegister、LOS_LmkOpsNodeUnregister和内存资源释放和任务恢复接口LOS_LmkTasksKill和LOS_LmkTasksRestore.
+* SwtmrHandlerItem结构体新增swtmrID字段，用于标识超时队列中软件定时器id
+* 新增支持API:
+
+LOS_LmsCheckPoolAdd使能检测指定内存池
+LOS_LmsCheckPoolDel不检测指定内存池
+LOS_LmsAddrProtect为指定内存段上锁，不允许访问
+LOS_LmsAddrDisableProtect去能指定内存段的访问保护

+
+
+### BREAKING CHANGES
+
+* 新增4个对外接口，声明在los_dynlink.h文件中，分别为：
+(1) LOS_DynlinkInit: 动态加载模块初始化。
+(2) LOS_SoLoad: 加载指定路径的共享库。
+(3) LOS_FindSym: 根据共享库句柄查找指定符号。
+(4) LOS_SoUnload: 卸载共享库。
+* 1.新增一系列trace的对外API，位于los_trace.h中.
+LOS_TRACE_EASY简易插桩
+LOS_TRACE标准插桩
+LOS_TraceInit配置Trace缓冲区的地址和大小
+LOS_TraceStart开启事件记录
+LOS_TraceStop停止事件记录
+LOS_TraceRecordDump输出Trace缓冲区数据
+LOS_TraceRecordGet获取Trace缓冲区的首地址
+LOS_TraceReset清除Trace缓冲区中的事件
+LOS_TraceEventMaskSet设置事件掩码，仅记录某些模块的事件
+LOS_TraceHwiFilterHookReg注册过滤特定中断号事件的钩子函数
+* 1.原调度中基于tick timer的低功耗扩展和当前的pm模块合并，删除原对外接口LOS_SchedSleepInit,
+　变为pm模块统一提供的LOS_PmRegistered接口.
+2.原来在arch los_timer.h下提供的低功耗模式为枚举LOS_SysSleepEnum，其中OS_SYS_NORMAL_SLEEP
+  和OS_SYS_DEEP_SLEEP不符合对外定义，统一修改为LOS_SYS_NORMAL_SLEEP和LOS_SYS_DEEP_SLEEP,
+  并移至los_pm.h中.
+3.VOID HalEnterSleep(LOS_SysSleepEnum sleep) 变更为UINT32 HalEnterSleep(VOID).

 OpenHarmony LiteOS-M内核是面向IoT领域构建的轻量级物联网操作系统内核，具有小体积、低功耗、高性能的特点，其代码结构简单，主要包括内核最小功能集、内核抽象层、可选组件以及工程目录等，分为硬件相关层以及硬件无关层，硬件相关层提供统一的HAL（Hardware Abstraction Layer）接口，提升硬件易适配性，不同编译工具链和芯片架构的组合分类，满足AIoT类型丰富的硬件和编译工具链的拓展。其架构图如图1所示：

 ### 搭建系统基础环境

-在搭建各个开发板环境前，需要完成OpenHarmony系统基础环境搭建。系统基础环境主要是指OpenHarmony的编译环境和开发环境，详细介绍请参考官方站点[开发环境准备](https://gitee.com/openharmony/docs/blob/HEAD/zh-cn/device-dev/quick-start/quickstart-lite-env-setup.md)。开发者需要根据环境搭建文档完成环境搭建。
