- **`Boot/`** — 自写精简 bootloader（链接在 `0x01000000`/16KB）：bootsetting 裁决 + 镜像 CRC32 校验 + VTOR 重映射跳转；首次无 bootsetting 时向量检查后直跳 APP1。

+- **`mcm-ddc-ble/`** — 独立 BLE 工程（基于 SDK rdtss 例程，链接在 `0x01000000`，无 bootloader/OTA）：BLE↔USART1 透传 + FreeRTOS（BLE 调度任务 + LED1 点灯任务），睡眠已锁保 SWD。日志在 `mcm-ddc-ble/docs/开发日志.md`。

 烧录与运行：

 1. Keil 打开 `MDK-ARM/embeddedSrc.uvprojx`，F7 编译
-2. NS-LINK 接 SWD（PA4/PA5），F8 下载
-3. 串口助手接 PB6(TX)/PB7(RX)，115200 8N1，复位后应看到启动 banner 与 `caiic->` CLI 提示符（输入 `help` 查看命令；LED 滚动日志默认关闭，用 `log on` 打开）
-4. BLE：手机 nRF Connect 应能搜到并连接 `CAIIC-MCM`，可见自定义服务（写特征 + notify 特征）

-注意：本工程当前尚未在真实硬件上实测（见开发日志第 8、9、10、15 节）。
+2. NS-LINK 接 SWD（PA4/PA5），F8 下载——Boot 跳转不校验镜像 CRC 后，Keil 直接下载 APP 即可正常启动调试；工程调试配置挂了 `MDK-ARM/debug_app.ini`（强制 SP/PC 从 APP1 向量表取，跳过 Boot 旁路，可选）
+3. 独立运行（脱调试器）需烧整片包：`tools\flash_package.bat tools\out\caiic_full.bin`（改代码后先 `make_package.bat` 重新出包）。**板子上烧过其他 0x01000000 起步的程序会覆盖 Boot/bootsetting，恢复靠重烧整片包**

+## 19. Boot 跳转策略调整：校验移到升级过程，解决 Keil 下载无法调试
+
+### 19.1 现象与根因
+
+加了诊断代码重新编译后，Keil 下载/调试**能连上但全速跑永远到不了 main**。根因：
+
+- Keil 下载只写 APP1 区（0x01000000 起的镜像由 Keil 的 FLM 按 axf 地址 0x01008000 写入），
+  **不会更新 bootsetting（0x01004000）里记录的 APP1 CRC32**——那是上次 `merge_image.py`
+  打整片包时算的。
+- 复位链路：芯片 ROM → Boot → 校验 bootsetting → 校验 APP1 镜像 CRC → **不匹配，拒绝跳转**，
+  CPU 停在 Boot 的 `for(;;)`。Keil 的 "Run to main" 走的是自然启动，自然卡在 Boot。
+- 所以任何一次 Keil 重新下载（不只是诊断代码）都会触发；引入 Boot 之前没有这层校验，故以前正常。
+
+验证方法：调试状态 halt 看 PC，落在 0x01000000~0x01003FFF 即 Boot 空转。
+
+### 19.2 调整内容
+
+- **Boot（`Boot/src/main.c`）改为跳转时不校验镜像 CRC**：只检查 bootsetting 扇区自身完整性
+  （magic + 自身 CRC32）选出 active bank，再做向量表 sanity（MSP 在 SRAM、复位向量在 bank 内）
+  兜底后直接跳转；bootsetting 无效时默认 APP1。删除 `bank_crc_ok()` 及双 bank CRC 回退。
+- **镜像 CRC 校验职责完全在升级过程**：`app_ota.c` OTA_END 已对新镜像整体 CRC32 比对，
+  通过才写 bootsetting 切 bank 复位——OTA 链路安全性不变。
+- 新增 `MDK-ARM/debug_app.ini` 并挂到工程调试配置（uvoptx `<tIfile>`）：调试器下载后强制
+  `SP/PC = APP1 向量表`，跳过 Boot 直进 APP。Boot 不校验后该脚本已非必需，保留为纯调试可选旁路。
+- Boot 重建 0E0W（`Code=1352`，bin 2032B），`tools/make_package.bat` 重新出整片包
+  （caiic_full 79464B）。
+
+### 19.3 影响与注意
+
+- Keil 直接下载 APP 即可启动和调试，开发节奏恢复。
+- 代价：OTA 流程之外的镜像损坏（如 Keil 下载中途断电）不再被 Boot 拦截——向量检查只能挡
+  全空/乱码。这是"简单"换来的取舍。
+- **在板子上烧过其他 0x01000000 起步的程序（SDK 例程 / mcm-ddc-ble）会覆盖 Boot 和
+  bootsetting**，恢复方法：`tools\flash_package.bat tools\out\caiic_full.bin` 重烧整片包。

+
+独立 BLE 工程：从 0x01000000 直接起跑（无 bootloader、无 OTA），用于在单镜像环境下
+验证 BLE 功能与后续功能开发。

+
+## 1. 工程创建（基于 SDK rdtss 例程）
+
+### 1.1 选型
+
+以 `nations-tec/N32WB03x_SDK_V2.0.0/projects/n32wb03x_EVAL/ble/rdtss` 为蓝本：
+BLE 原始数据透传服务（128-bit UUID，下行写 + 上行 notify），与 mcm-ddc-04 的自定义
+GATT 透传服务（CLS）形态最接近，适合作为手机 APP 通信协议的载体。heart_rate 是标准
+profile，不适合做数据通道。
+
+### 1.2 移植方式
+
+- 整目录复制 `src/`、`inc/`、`MDK-ARM/` 到 `mcm-ddc-ble/`，工程改名 `mcm-ddc-ble`，
+  输出 `bin/mcm-ddc-ble.bin`。
+- uvprojx/uvoptx 中 268+11 处 SDK 相对路径由 `..\..\..\..\..\` 重定向为
+  `..\..\nations-tec\N32WB03x_SDK_V2.0.0\`（新工程深度不同）；
+  另有 11+3 处 `..\..\..\dfu\common` 指向 SDK 的 `projects/n32wb03x_EVAL/dfu/common`。
+  `nations-tec/` 只读，未做任何修改。
+- 只使用第一个 target `N32WB03x`（IROM 0x01000000/0x40000）；`OTA_IMG_1`/`OTA_IMG_2`
+  两个 target 未适配（其 after-build 脚本会写 SDK 目录），不要构建。
+
+### 1.3 引脚核对（重点：避开 SWD）
+
+- SWD 调试管脚：SWCLK=PA4 / SWDIO=PA5，全工程无任何占用。
+- LED1=PB0、LED2=PA6（与 mcm-ddc-04、STB 板一致）。
+- USART1 透传通道：TX=PB6 / RX=PB7（AF4，115200 8N1），与我们板子一致。
+- 日志 LPUART：TX=PB1（NS_LOG）。
+- `app_usart.h` 里的 PIN_4/PIN_5 是被注释掉的 USART2 备选（PB4/PB5），无影响。
+
+### 1.4 保 SWD：禁止睡眠
+
+例程主循环会进 deep sleep，SWD 随之断开（readme 也提示需 RESET 时机烧录）。
+在 `main.c` 主循环前调用 `ns_sleep_lock_acquire()` 永久锁睡眠，SWD 全程可调试；
+代价是功耗偏高（仅调试阶段，后续做低功耗时再评估）。
+
+### 1.5 构建
+
+`UV4 -b mcm-ddc-ble.uvprojx -t "N32WB03x"`：0 Error / 0 Warning，
+`Code=23340 RO-data=3352 RW-data=1876 ZI-data=6052`，bin 28224B。

+
+## 2. 接入 FreeRTOS + 点灯任务
+
+### 2.1 内容
+
+- 内核：SDK 自带 FreeRTOS V9（`middlewares/Third_Party/FreeRTOS`），工程新增 FREERTOS 组：
+  `tasks/queue/list/timers.c` + `heap_4.c` + `port.c`（RVDS/ARM_CM0），只加进 `N32WB03x` target。
+- `inc/FreeRTOSConfig.h`：从 mcm-ddc-04 移植，heap 缩为 **8KB**（本工程仅 3 个任务）；
+  SVC/PendSV/SysTick 由 port 接管（宏映射），本工程无 `n32wb03x_it.c`，无重复定义问题。
+- `main.c` 任务化：
+  - `ble_schedule_task`（512 字栈，优先级 2）：`rwip_schedule()` + 1ms 延时，
+    替代裸机 while 循环（rwip 只允许单上下文运行）。
+  - `led_task`（128 字栈，优先级 1）：LED1(PB0) 每 500ms 翻转做运行指示；
+    LED2(PA6) 仍由 app_ble.c 驱动作连接状态指示。
+  - 睡眠保持锁定（deep sleep 与 RTOS tick 冲突，且保 SWD）。
+- 串口透传路径为事件驱动（`usart_forward_to_ble_loop` 由 profile 回调触发、
+  `app_usart_tx_process` 由 BLE 消息处理触发），rwip_schedule 进任务后行为不变。
+
+### 2.2 踩坑记录
+
+脚本往 uvprojx 写路径时 `\t` 被 Python 解释成制表符（`Source\tasks.c` → `Source<TAB>asks.c`），
+Keil 报 `cannot create command input file 'source tasks.__i'`；另外 `<FileName>` 必须写纯文件名
+（带路径会被 Keil 当成对象名，同样报此错）。修正后全量重建通过。
+
+### 2.3 构建
+
+0 Error / 0 Warning，`Code=24736 RO-data=3352 RW-data=1964 ZI-data=14484`；
+bin ≈ 27.4KB，RAM（RW+ZI）≈ 16.1KB / 48KB（含 8KB FreeRTOS heap）。
+
+### 2.4 上板预期
+
+LED1 每 500ms 闪烁；手机可搜到并连接 `NS_RDTSS`，连接后 LED2 亮；
+串口（PB6/PB7，115200）与手机 BLE 互发透传。
