# PBL/XBL 日志
Source: [https://docs.qualcomm.com/doc/80-70014-4Y/topic/bootloader-logs.html](https://docs.qualcomm.com/doc/80-70014-4Y/topic/bootloader-logs.html)
示例中的 primary boot loader/eXtensible boot loader (PBL/XBL) 日志表示 PBL 和 XBL 的开始和结束。
有关 PBL 和 XBL 的详细信息，请参见 [Boot loader](https://docs.qualcomm.com/doc/80-70014-4Y/topic/bootloader.html)。
下表列出了有助于验证 boot loader 的开始和结束的日志条目：
Table : 检查 PBL/XBL 日志
| 日志条目 | 说明 |
| --- | --- |
| `S - Boot Interface: UFS` | 表示从 UFS 启动软件镜像，因为启动介质存储在 UFS 中 |
| `S - PBL Patch Ver: 1` | 表示 PBL 的开始 |
| `S - 69043 - PBL, End` | 表示 PBL 的结束 |
| `B - 79574 - SBL1, Start` | 表示 XBL 的开始
Note: SBL1 和 XBL 是指相同的二级 boot loader。 |
| `B - 1394338 - SBL1, End` | 表示 XBL 的结束 |
| `D - 1318210 - SBL1, Delta` | 表示 XBL 开始和结束之间的时间差（以微秒为单位） |
