* @file boot_main.c
|
||||
* @brief 可配置 OTA Bootloader — PY32F040
|
||||
*
|
||||
* 三种模式（由 ota_config.h 的 OTA_BACKUP_MODE / OTA_SWAP_STRATEGY 决定）：
|
||||
*
|
||||
* ① 单备份（SINGLE）：
|
||||
* PENDING → 校验 BAK → 拷贝覆盖主区 → 跳转主区（无回滚）
|
||||
* 掉电：PENDING 不清除，下次启动重新校验+拷贝（BAK 完好，天然安全）
|
||||
*
|
||||
* ② 双备份 + RAM 缓冲交换（AB + RAM）：
|
||||
* PENDING → 校验 B 区 → 逐页交换（RAM 双页缓冲）→ BOOT_NEW → 跳转 A 区
|
||||
* SWAPPING → 交换掉电中断，续做（phase/progress 恢复）
|
||||
* BOOT_NEW 未确认（崩溃/IWDG 复位）→ 反向交换回滚 → 跳转 A 区
|
||||
*
|
||||
* ③ 双备份 + Flash 暂存区交换（AB + SCRATCH）：
|
||||
* 同上，但交换用 scratch 暂存一页（Flash 持久），掉电恢复可完整保留两页，
|
||||
* 回滚永远可用；升级耗时更短。
|
||||
*
|
||||
* 跳转新固件前使能 IWDG：新固件崩溃则看门狗复位，Bootloader 再次判定并回滚。
|
||||
* 交换/拷贝期间使能 IWDG 并逐页喂狗（单页耗时 < 100ms，远小于 1s 超时）。
