|
||||
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。
|
||||

|
||||
* 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).

This option turns on the -fstack-protector GCC feature. This
|
||||
feature puts, at the beginning of functions, a canary value on
|
||||
the stack just before the return address, and validates
|
||||
the value just before actually returning. Stack based buffer
|
||||
overflows (that need to overwrite this return address) now also
|
||||
overwrite the canary, which gets detected and the attack is then
|
||||
neutralized via a kernel panic.
|
||||
|
||||
This feature requires gcc version 4.2 or above, or a distribution
|
||||
gcc with the feature backported. Older versions are automatically
|
||||
detected and for those versions, this configuration option is
|
||||
ignored. (and a warning is printed during bootup)

## Introduction<a name="section11660541593"></a>
|
||||
|
||||
OpenHarmony LiteOS-M is a lightweight operating system kernel designed for the Internet of Things (IoT) field. It features small footprint, low power consumption, and high performance. It has a simple code structure, including the minimum kernel function set, kernel abstraction layer, optional components, and project directory. The LiteOS-M kernel is divided into the hardware layer and hardware-irrelevant layers. The hardware layer provides a unified hardware abstraction layer (HAL) interface for easier hardware adaptation. A range of compilation toolchains can be used with different chip architectures to meet the expansion of diversified hardware and compilation toolchains in the Artificial Intelligence of Things (AIoT) field.
|
||||
**Figure1** shows the architecture of the LiteOS-M kernel.
|
||||
The OpenHarmony LiteOS Cortex-M is the kernel designed for the lightweight operating system \(OS\) for the Internet of Things \(IoT\) field. It features small size, low power consumption, and high performance. In addition, it has a simple code structure, including the minimum kernel function set, kernel abstraction layer, optional components, and project directory, and is divided into the hardware-related and hardware-irrelevant layers. The hardware-related layers provide unified hardware abstraction layer \(HAL\) interfaces to improve hardware adaptability. The combination and classification of different compilation toolchains and chip architectures meet the requirements of the Artificial Intelligence of Things \(AIoT\) field for rich hardware and compilation toolchains. [Figure1](#fig0865152210223) shows the architecture of the OpenHarmony LiteOS Cortex-M kernel.

OpenHarmony LiteOS-M supports only C and C++.
|
||||
Programming languages: C and C++
|
||||
|
||||
Applicable architecture: See the directory structure for the arch layer.
|
||||
|
||||
As for dynamic loading module, the shared library to be loaded needs signature verification or source restriction to ensure security.
|
||||
Currently applicable architectures: Cortex-M3, Cortex-M4, Cortex-M7, and RISC-V
|
||||

The OpenHarmony LiteOS-M kernel build system is a modular build system based on Generate Ninja (GN) and Ninja. It supports module-based configuration, tailoring, and assembling, and helps you build custom products. This document describes how to build a LiteOS-M project based on GN and Ninja. For details about the methods such as GCC+gn, IAR, and Keil MDK, visit the community websites.
|
||||
|
||||
### Setting Up the Environment
|
||||
|
||||
Before setting up the environment for a development board, you must set up the basic system environment for OpenHarmony first. The basic system environment includes the OpenHarmony build environment and development environment. For details, see [Setting Up Development Environment](https://gitee.com/openharmony/docs/blob/master/en/device-dev/quick-start/Readme-EN.md).
|
||||
|
||||
### Obtaining the OpenHarmony Source Code
|
||||
|
||||
For details about how to obtain the source code, see [Source Code Acquisition](https://gitee.com/openharmony/docs/blob/HEAD/en/device-dev/get-code/sourcecode-acquire.md). This document assumes that the clone directory is `~/openHarmony` after the complete OpenHarmony repository code is obtained.
|
||||
|
||||

|
||||
|
||||
```
|
||||
mkdir ~/openHarmony/device/st
|
||||
|
||||
cp -r ~/nucleo_f767zi/device/st/nucleo_f767zi ~/openHarmony/device/st/nucleo_f767zi
|
||||
|
||||
chmod +x ~/openHarmony/device/st/nucleo_f767zi/build.sh
|
||||
|
||||
cp -r ~/nucleo_f767zi/vendor/st ~/openHarmony/vendor/st
|
||||

|
||||
|
||||
### 编译运行
|
||||
|
||||
编译运行前，交叉编译工具链`bin`目录配置到`PATH`环境变量中或者配置`device/st/nucleo_f767zi/liteos_m/config.gni`文件中`board_toolchain_path`配置项为交叉编译工具链`bin`目录。
|
||||
在`OpenHarmony`根目录，执行`hb set`设置产品路径，选择`nucleo_f767zi`产品，然后执行`hb build`开启编译。如下：
|
||||
|
||||
```
|
||||
user@dev:~/OpenHarmony$ hb set
|
||||
|
||||
[OHOS INFO] Input code path: # 直接按回车，然后选择nucleo_f767zi产品即可
|
||||
|
||||
OHOS Which product do you need? nucleo_f767zi@st
|
||||
|
||||
user@dev:~/OpenHarmony$ hb build
|
||||
```
|
||||
|
||||
最终的镜像生成在`~/openHarmony/out/nucleo_f767zi/`目录中，通过`STM32 ST-LINK Utility`软件将镜像文件下载至单板查看运行效果。
