# PBL/XBL log The sample primary boot loader/eXtensible boot loader (PBL/XBL) log indicates the start and end of the PBL and XBL. For more information on PBL and XBL, see [Boot loader](https://docs.qualcomm.com/doc/80-70017-4/topic/architecture.html#bootloader). The table lists log entries that can help you verify the start and end of the boot loaders. Table : Checking PBL/XBL log | Log entry | Description | | --- | --- | | `S - Boot Interface: UFS` | Indicates the booting of Qualcomm Linux software images from UFS
as the boot image is stored in UFS. | | `S - PBL Patch Ver: 1` | Indicates the start of PBL. | | `S - 69043 - PBL, End` | Indicates the end of PBL. | | `B - 79574 - SBL1, Start` | Indicates the start of XBL. Both SBL1 and XBL refer to the same
secondary boot loader. | | `B - 1394338 - SBL1, End` | Indicates the end of XBL. | | `D - 1318210 - SBL1, Delta` | Indicates the time difference in microseconds between start and
end of XBL. | Note The numbers in the log entry column of the table show the timestamp in microseconds. The following is a sample log: Format: Log Type - Time(microsec) - Message - Optional Info Log Type: B - Since Boot(Power On Reset), D - Delta, S - Statistic S - QC\_IMAGE\_VERSION\_STRING=BOOT.<XX.x.x.xx-xxxxx-XXXXX-x> S - IMAGE\_VARIANT\_STRING=Soc<XXXXXXX> S - OEM\_IMAGE\_VERSION\_STRING=ip-<xx-xxx-xxx-xx>\*\* S - Boot Interface: UFS\*\* S - Secure Boot: Off S - Boot Config @ 0x00786070 = 0x000000c1 S - JTAG ID @ 0x00786130 = 0x001980e1 S - OEM ID @ 0x00786138 = 0x00000000 S - Serial Number @ 0x00786134 = 0xf744c1e9 S - OEM Config Row 0 @ 0x007841c0 = 0x0000000000000000 S - OEM Config Row 1 @ 0x007841c8 = 0x0000000000000000 S - Feature Config Row 0 @ 0x00784148 = 0x0000000000000000 S - Feature Config Row 1 @ 0x00784150 = 0x0000000000000000 S - Core 0 Frequency, 1516 MHz\*\* S - PBL Patch Ver: 1\*\* D - 6626 - pbl\_apps\_init\_timestamp D - 31574 - bootable\_media\_detect\_timestamp D - 853 - bl\_elf\_metadata\_loading\_timestamp D - 704 - bl\_hash\_seg\_auth\_timestamp D - 6621 - bl\_elf\_loadable\_segment\_loading\_timestamp D - 4638 - bl\_elf\_segs\_hash\_verify\_timestamp D - 17185 - bl\_sec\_hash\_seg\_auth\_timestamp D - 811 - bl\_sec\_segs\_hash\_verify\_timestamp D - 31 - pbl\_populate\_shared\_data\_and\_exit\_timestamp\*\* S - 69043 - PBL, End B - 79574 - SBL1, Start\*\* B - 210297 - SBL1 BUILD @ <XXXXXXX> B - 214445 - usb: usb\_shared\_xbl\_dtb\_node\_init dtb status , 0x3 B - 223717 - usb: HS: device tree Not available , 0x3 B - 224114 - usb: eud\_serial\_upd , 0xf744c1e9 D - 229421 - sbl1\_hw\_init D - 519 - media\_init:1 D - 0 - smss\_load\_cancel B - 239455 - SMSS - Image Load, Start D - 3111 - SMSS - Image Loaded, Delta - (0 Bytes) D - 1037 - Auth Metadata D - 5825 - sbl1\_xblconfig\_init B - 254522 - XBL Config - Image Load, Start B - 258640 - DTB Found: [pre-ddr][7601f201000000][0] D - 4453 - boot\_pre\_ddr\_dtb\_load B - 267851 - UFS Device Tree Settings B - 271206 - UFS Init Speed: HS Enabled 1, Gear 4 2 Lane Rate 2 B - 280874 - UFS Perf Speed: HS Enabled 1, Gear 4 2 Lane Rate 2 B - 287096 - UFS Timeouts(us): fDeviceInit 2500000, UTRD Poll 30000000 D - 45323 - media\_init:2 B - 387868 - UFS INQUIRY ID: SAMSUNG KM2L9001CM-B518 0700 B - 389485 - UFS Boot LUN: 1 B - 400953 - UFS GEAR: 3 D - 95099 - media\_init:3 D - 30 - shrm\_load\_cancel B - 410835 - SHRM - Image Load, Start D - 702 - Auth Metadata D - 1403 - Segments hash check D - 12230 - SHRM - Image Loaded, Delta - (35752 Bytes) D - 0 - boot\_default\_cdt\_init D - 488 - boot\_cdt\_init B - 435540 - CDT - Image Load, Start B - 438407 - CDT Version:3,Platform ID:32,Major ID:1,Minor ID:0,Subtype:2 D - 16928 - sbl1\_hw\_platform\_pre\_ddr D - 0 - devcfg init B - 464942 - PMIC A:2.0 B:1.0 C:2.2 I:1.0 B - 466772 - PM: PM8 0x4 B - 469181 - PM: xVdd reset B - 471835 - PM: PON by SYSOK B - 724497 - PM: SET\_VAL:Skip B - 724527 - PM: Verifying PON-Trigger specific configurations & current PON-Trigger B - 733281 - PM: All PON-Trigger specific configs verified.
