-# LiteOS
-
-# 一、环境安装
-
-### 1. 安装docker环境
-
-[docker加载镜像下载]
-
-链接: https://pan.baidu.com/s/1GVossI98riHL2xEzo7HmMQ?pwd=we75 提取码: we75
-
-```console
-$ cd docker_package
-$ sudo dpkg -i containerd.io_1.5.11-1_amd64.deb
-$ sudo dpkg -i docker-ce-cli_20.10.14_3-0_ubuntu-focal_amd64.deb
-$ sudo dpkg -i docker-ce_20.10.14_3-0_ubuntu-focal_amd64.deb
-```
-
-docker加载liteos-env镜像
-
-```console
-$ cd docker_images
-$ sudo docker load -i openharmony-v31.tar
-```
-
-### 2. 下载源代码
-
-[LiteOS v3.1](https://gitee.com/link?target=https%3A%2F%2Frepo.huaweicloud.com%2Fharmonyos%2Fos%2F3.1-Release%2Fcode-v3.1-Release.tar.gz)
-
-### 3. 将用户添加到docker用户组
-
-```console
-$ sudo groupadd docker
-$ sudo gpasswd -a $USER docker
-$ newgrp docker
-$ ./run_docker.sh
-```
-
-### 4.编译liteos-a内核和应用
-
-编译 hb set 使用上下方向键盘选择"qemu_small_system_demo"
-hb build编译
-
-```console
-root@62deba27a240:/home/openharmony# hb set
-root@62deba27a240:/home/openharmony# hb build -f
-```
-
-运行
-
-```console
-root@62deba27a240:/home/openharmony# ./qemu-run -f
-```
-
-等待内核在qemu下加载完成，回车，进入OHOS shell
-如果无法进入，请检查out目录下是否存在smallmmc.img，不存在请复制smallmmc.img到out目录下
-并重新编译执行
-
-
-```console
-root@62deba27a240:/home/openharmony# ./qemu-run -f
-Redo making flash.img...
-
-Start making flash.img...

-
-回车之后进入OHOS shell
-
-```console
-OHOS:/$ cd bin
-OHOS:/bin$
-```
-
-测试结束
-
-Ctrl-A + x 退出Qemu模拟环境
-
-
-
-# 二、命令行调试liteOS
-
-### 1、安装`gdb-multiarch`工具包(docker 容器中安装)：
-
-```shell
-$ apt install gdb-multiarch
-```
-
-### 2、修改`debug.config`文件
-
-```shell
-$ cd ./vendor/ohemu/qemu_small_system_demo/kernel_configs
-$ vim debug.config
-```
-
-将 `LOSCFG_CC_STACKPROTECTOR_ALL=y` 修改为:
-
-```shell
-# LOSCFG_CC_STACKPROTECTOR_ALL is not set
-LOSCFG_COMPILE_DEBUG=y
-```
-
-### 3、重新编译项目
-
-保存并退出，在OHOS根目录重新编译:
-
-```shell
-$ hb build -f
-```
-
-### 4、debug LiteOS
-
-在一个窗口中输入命令：
-
-```shell
-$ ./qemu-run -g
-```
-
-在另一个窗口中输入命令：
-
-```shell
-$ docker exec -it ohos /bin/bash
-$ gdb-multiarch out/arm_virt/qemu_small_system_demo/OHOS_Image
-(gdb) target remote localhost:1234
-(gdb) b main
-Breakpoint 1 at 0x4005110c: file ../../../kernel/liteos_a/kernel/common/main.c, line 36.
-(gdb) c
-Continuing.
-
-Breakpoint 1, main () at ../../../kernel/liteos_a/kernel/common/main.c:36
-36 {
-(gdb) l
-31
-32 #include "los_config.h"

-36 {
-37 UINT32 ret = OsMain();
-38 if (ret != LOS_OK) {
-39 return (INT32)LOS_NOK;
-40 }
-(gdb) q
-```
-
-* gdb 调试常用代码
-
- 1、 b (break) :设置断点
-
- 2、 r (run): 运行程序
-
- 3、 bt (backtrace): 显示程序栈
-
- 4、 Print : 打印变量
-
- 5、 c (continue): 继续运行程序，直到下一个断点停止
-
- 6、 n (next) : 单步运行程序，不进入函数
-
- 7、 l (list) : 查看当前代码（显示当前后10行）
-
- 8、 edit (+function): 查看函数代码
-
- 9、 S (step) : 进入函数执行代码
-
- 10、 Q(Quit)：退出gdb
-
- 11、 Info b : 查看断点信息
-
-
-
-# 三、VSCode调试liteOS
-
-### 1、安装VScode
-
-```shel
-$ sudo apt install code
-```
-
-### 2、安装VScode 插件
-
-
-
-### 3、连接docker
-
-选择CONTAINERS目录下openharmony:v3.1...，右键选择附加VScode
-
-
-
-### 4、给docker安装VScode插件
-
-* 注意插件一定要安装在docker容器中
-
-
-
-### 5、配置launch.json文件
-
-```json
-{
- "version": "0.2.0",
- "configurations": [
- {
- "name": "debug liteOS",
- "type": "cppdbg",
- "request": "launch",
- "program": "${workspaceFolder}/out/arm_virt/qemu_small_system_demo/OHOS_Image",
- "args": [],
- "stopAtEntry": true,
- "cwd": "${workspaceFolder}",
- "miDebuggerServerAddress": "localhost:1234",
- "miDebuggerPath": "/usr/bin/gdb-multiarch",
- "environment": [],
- "externalConsole": false,
- "MIMode": "gdb",
- "setupCommands": [
- {
- "description": "pretty printing",
- "text": "-enable-pretty-printing",
- "ignoreFailures": true
- }
- ],
- "logging": {
- "engineLogging": true,
- "programOutput": true,
- },
- }
- ]
-}
-```
-
-### 6、新建终端
-
-运行
-
-```shell
-./qemu-run -g
-```
-
-### 7、vscode debug
-
-点击debug
-
