+## 20. 串口波特率提升到 1Mbps
+
+### 20.1 可行性核实
+
+- USART1 挂 APB2=64MHz（`n32wb03x_usart.c` 中 USART1 取 Pclk2），波特率发生器为
+  16 倍过采样 + 小数分频（同 STM32F1 算法）。
+- 1Mbps 分频值 = 64MHz / (16 × 1M) = **4.0，误差 0%**（2M/4M 同样零误差）。
+- 驱动断言上限 `IS_USART_BAUDRATE` = 4Mbps（`n32wb03x_usart.h`），1Mbps 远在范围内。
+
+### 20.2 改动
+
+- `bsp_usart.h`：`BSP_USART_BAUDRATE` 115200 → **1000000**，相关注释与 AGENTS.md 同步。
+- 构建 0E0W（`Code=38080 RO-data=6932 RW-data=10600 ZI-data=33056`）。
+- 注意：串口助手需切到 1000000；USB 转串口适配器需支持 1Mbps（CH340/CH343/FTDI 均可）。
+
+### 20.3 决策：RX 暂不切 DMA
+
+评估了 RX 由 RXDNE 逐字节中断改为 DMA 循环缓冲 + IDLE 中断的方案，结论**维持现状**：
+
+- CLI 是人工输入速度，1Mbps 下逐字节中断负载可忽略；RX DMA 的收益只在串口灌大数据
+  （有线烧录/批量注入）时才存在，属出现需求后再做。
+- DMA RX 引入循环缓冲管理、IDLE 中断、4 通道合一的 DMA IRQ 与 FromISR 优先级约束等
+  新出错点；现 RXDNE 方案已上板验证。
+- 对 CLI 语义无影响（保持 `bsp_usart_read_byte()` 字节流接口即可），但无收益不改动。
