+    ↓

+```
+
+### 1.2 `INIT_BOARD_EXPORT`、`INIT_APP_EXPORT`自动初始化原理
+
+>
+> RT‑Thread 自动初始化机制，**靠编译器段属性，把初始化函数指针放到特定内存段**，系统启动的时候遍历该段，自动调用函数，不需要手动写函数调用。
+
+1. `INIT_BOARD_EXPORT(fn)`：板级初始化，属于`INIT_BOARD`段，在`rt_hw_board_init()`里面执行；
+适合硬件外设初始化：串口、GPIO、ADC。
+2. `INIT_APP_EXPORT(fn)`：应用层初始化，属于`INIT_APP`段，调度器启动之后、进入 main 之前执行；
+适合应用组件、软件模块初始化。
+
+底层实现：
+宏展开后，定义一个静态`rt_init_handler_t`函数指针变量，加上编译器`__attribute__((section(".rti_fn.xxx")))`，把这个变量放置到专门的初始化段。
+编译链接时，所有被该宏修饰的函数指针全部收集到同一片内存段。系统启动时，直接遍历这个段内全部函数指针，逐个调用，实现自动执行。
+
+优先级：`INIT_BOARD`早于`INIT_APP`。
+
+## 2. 内核基础与对象模型
+
+### 2.1 RT‑Thread 面向对象设计思想
+
+RT‑Thread 内核采用面向对象 C 语言实现，不依靠 C++。
+所有内核资源（线程、信号量、互斥锁、队列）都有对应的**控制块结构体**。
+
+- `struct rt_object`是基类，包含对象类型、名字、链表节点；
+- 线程、信号量等控制块**继承这个基对象**（结构体第一个成员为`struct rt_object`）；
+内核统一对象容器链表管理所有内核对象，可以遍历、查找。
+
+#### `struct rt_thread`关键成员
+
+| 成员               | 作用                                                         |
+| ------------------ | ------------------------------------------------------------ |
+| `stat`             | 线程状态，标记：初始、就绪、运行、挂起、关闭；调度器依据该状态管理线程 |
+| `current_priority` | 当前优先级，0 为最高；抢占调度依据优先级，可运行时动态修改   |
+| `init_tick`        | 线程时间片，时间片轮转调度；时间片耗尽触发调度               |
+| `sp`               | 线程栈指针；上下文切换时保存 / 恢复 SP，用来保存线程现场     |
+
+### 2.2 静态对象 vs 动态对象
+
+| 对比项   | 静态对象                                  | 动态对象                                |
+| -------- | ----------------------------------------- | --------------------------------------- |
+| 分配位置 | 编译期分配，存全局 / 静态内存（data/bss） | 运行时`rt_malloc`，从堆内存分配         |
+| 生命周期 | 程序整个运行周期，不会自动销毁            | 调用rt_malloc`创建；`rt_free`释放       |
+| 释放机制 | 不需要 free；不能手动释放                 | 必须手动`rt_free`；忘记释放造成内存泄漏 |
+
+> 高可靠场景强制静态线程原因：
+
+1. 堆内存`malloc`会存在内存碎片，长期运行会分配失败；
+2. 静态对象内存编译期就确定，运行时不会分配失败；
+3. 嵌入式高可靠设备不能接受运行时内存分配失败导致系统崩溃，所以使用静态线程。
+
+## 3. 线程状态机与调度算法
+
+### 3.1 RT‑Thread 五态模型
+
+**5 种状态：初始态、就绪态、运行态、挂起态、关闭态**
+
+1. **初始态 (INIT)**：线程已经初始化，还未加入就绪队列。
+API：`rt_thread_init()` / `rt_thread_create()`创建完，处于初始态。
+→调用`rt_thread_startup()`，切换到**就绪态**。
+2. **就绪态 (READY)**：线程一切准备完毕，等待 CPU 时间。放在就绪链表，调度器可以选中。
+   - 高优先级线程就绪 → 抢占，低优先级从运行→就绪；
+   - 时间片用完，本线程运行→就绪。
+3. **运行态 (RUNNING)**：当前正在占用 CPU 执行，系统同一时刻只有 1 个线程处于运行态。
+   - 调用阻塞 API（信号量等待、延时） → **挂起态**；
+   - 时间片耗尽 → 就绪态；
+   - 更高优先级就绪线程抢占 → 就绪态。
+4. **挂起态 (SUSPEND)**：线程阻塞，不参与调度。
+触发：`rt_thread_delay()`、`rt_sem_take()`等待不到资源；
+资源到位 / 延时结束 → 切换回就绪态。
+5. **关闭态 (CLOSE)**：线程执行结束，不再参与调度。
+API：`rt_thread_close()`；静态线程回到初始，动态线程可以释放内存。
+
+>
+> 状态流转：
+> 初始 →(startup)→ 就绪 →(调度选中)→运行
+> 运行 →(阻塞 / 延时)→挂起 →(资源到达)→就绪
+> 运行 →(线程结束 /close)→关闭
+
+### 3.2 调度机制剖析
+
+1. **抢占式调度**
+只要有**更高优先级线程进入就绪态**，立刻抢占当前正在运行的低优先级线程，保存现场，切换至高优先级线程运行。
+
+>
+> 中断里面释放信号量，唤醒高优先级线程，中断退出瞬间就完成抢占。保证高优先级任务及时响应。
+
+2. **时间片轮转调度**
+针对**相同优先级**的多个就绪线程。每个线程分配时间片`init_tick`。
+线程运行消耗 tick，时间片耗尽，调度器切换同优先级下一个就绪线程。
+
+>
+> 不同优先级，时间片不起作用，高优先级优先执行。
