分区: Boot 32KB | A区0x8000(29扇区232KB,运行) | B区0x42000(29扇区232KB,暂存) | 参数区0x7C000不变 流程: 仅擦B区下载→CRC32(B)通过→逐扇区搬运B→A→CRC32(A)通过→擦B区→置APP_BOOT_UPGRADE_FLAG复位 防变砖: 下载超时/CRC失败/AppSize非法均恢复APP_START_FLAG复位回老App; 断电续传靠重启后B区CRC判定 其他: GetCrc32/AppWriteFlash/EraseFlash基址参数化, FlashWrite尾字节0xFF补齐, 0x82增加状态守卫 协议与boot_para_t结构不变, 主机升级工具无需修改
