背景: 设备挂平台测试出现重复上线(现场未断电), 无本地日志无法区分
设备真复位 vs MQTT 断连重连。iot_handle_suback 每次重连都发
initialize 是重复上线的直接证据, 日志需能区分二者。
实现 (V3.6, ROADMAP P1.2 事件流先行):
- offlog.c/h: W25Q32 256KB 环形事件日志 (头扇区+63数据扇区, 8064条)
- 32B 定长记录: magic/type/len/flags/seq/ts_ms/unix_ts/boot_seq/payload[12]
- 8 类事件: BOOT(复位原因)/IOT_CONNECT/READY/DISCONN/RECONN/
EVT_RETRY/GIVEUP/COIL/TIME_ANCHOR/LOG_CLEAR
- 掉电恢复: 头扇区写指针锚点 + 上电 seq 连续性扫描
- 编译期断言防 32B padding 回归
- 插桩 (全部主循环上下文, socket 中断内不写 SPI):
- main(): offlog_init + RCC_RSTSCKR 复位原因采集/清除
- iot_mqtt_poll(): MQTT 状态沿检测 (CONNECT/READY/DISCONN)
- 重连退避/TCP超时/CONNACK拒绝: RECONN/DISCONN(4)/(3)
- iot_evt_process/enqueue: EVT_RETRY/GIVEUP/COIL
- net_srv.c dev_time_sync: TIME_ANCHOR 时钟同步锚点
- tests/test_offlog.c: gcc 隔离单测 6 例 (mock W25Q32 NOR 语义)
关键坑: ①中断内写SPI阻塞 ②结构体36B padding致环形错乱
③扇区级覆盖粒度count扣减语义 (均单测抓出)
待办: P1.3 导出命令(log_query/stat/clear) + 快照流 + 复位原因板上验证
