问题描述

最开始通过uBMC更新BIOS是成功的，后来调试其他功能后，更新BIOS发现网页提示更新成功，实际没有更新Flash,回退版本也是这个现象，通过测量uBMC上的BMC_SFC_SEL信号，没有发出切换信号，通过查看log文件，与正常更新文件对比，***[bios]upgrade package: the power status is not off，***这部分就报错了，这个power status是什么哪里来的？后续应该怎么查？

答案内容由AI生成，仅供参考：

结论总结

  • 根因：您遇到的“升级成功但未刷新Flash”是因为升级是在服务器上电状态下进行的。系统采取了“缓存升级”策略，日志中 [bios]upgrade package: the power status is not off 的报错正是该机制的直接体现。在此模式下，系统不会进行实际的Flash写入，而是等待系统下电后生效。所以Flash内容未被改变。
  • 后续建议：
    1. 首选方案：在服务器完全下电后，重新执行BIOS升级操作。这应该能解决问题。
    2. 根本方案：定位并修复上电状态下BMC获取的“电源状态”不正确的问题。重点排查CPLD与BMC之间的电源状态信号交互逻辑，以及/bmc/kepler/Systems/1/Bios资源树的加载情况。您提到“CPLD不一样”是非常关键的线索。
点击此处查看详细分析解答

好的，作为一名信息合成专家，我将严格依据您提供的 上下文 来分析和解答您的问题。

首先，根据您提供的日志，关键信息是：[bios]upgrade package: the power status is not off。这表明BIOS升级过程因为检测到系统电源状态不是“关闭”而中断了。

根据知识图谱中的信息，BIOS Upgrade（BIOS升级）是一个关键系统级操作，其成功执行依赖特定条件，例如系统处于下电状态。此外，知识图谱也指出，系统状态（如未下电）和缺少配置是导致升级失败的常见原因。

以下是结合您提供的信息所做的详细分析和后续排查建议：

问题分析与后续排查指南

根据您提供的日志和环境信息，您遇到的“UBMC更新BIOS显示成功，实际没有更新Flash”的问题，其核心原因已经定位。

1. power status 是什么？来源于哪里？

日志中出现的 ***[bios]upgrade package: the power status is not off*** 指出，在BIOS升级的Cache（缓存）阶段，升级流程检测到服务器的电源状态不为“关闭”（OFF）。

  • 来源：这个状态是由 BMC (Baseboard Management Controller) 自身监控和维护的。BMC负责监控和管理服务器的硬件状态，包括电源状态。
  • 含义：在升级过程中，特别是在执行“普通升级”或需要直接写入Flash的模式时，系统要求服务器处于下电（Power Off）状态。这是因为：
    • 写入Flash（SPI Flash）时，需要BMC通过SFC总线获得Flash的控制权。
    • 如果服务器处于上电状态，BIOS可能正在使用Flash，或者BIOS/BMC的电源管理逻辑（如LockPower执行器）会阻止写入操作，以防止数据损坏或系统不稳定。
    • 您日志中报错“power status is not off”之后，流程直接跳过后续的SpiDriver、SelectChannel、UpgradeComponent等关键执行器，直接进入结束阶段，所以没有写入Flash。

2. 为什么“网页提示更新成功”？

这是一个常见的现象，根据 Document Chunk 中的信息，当升级模式为非装备模式且系统处于上电状态时，升级策略会是“缓存升级”。

  • 机制：系统会将新固件包缓存起来，并记录“升级成功”，但实际上并未写入BIOS Flash。真正的写入操作会延后到下一次系统下电或复位时执行。
  • 您的日志佐证：日志中 upgrade mode(Cold), period(Period2), package type(Normal) 明确指出这是一个 Normal（普通）模式。并且，流程在执行到 Cache executor 时因电源非OFF而停止，这正好印证了这是一个需要下电才能生效的缓存操作。

3. 后续应该怎么查？

结合环境信息中的描述（“其他项目正常，CPLD不一样”），问题可能出在电源状态与升级流程的联动上。请按以下步骤排查：

  1. 检查升级模式：

    • 确认您使用的升级包是否为“装备包”（Manufacture/装备升级）。装备包会执行强制上下电，可以绕开这个问题。
    • 对于普通包，必须在下电状态下升级。

  2. 确认电源管理逻辑：

    • 硬件层面：联系硬件团队或参考硬件设计文档，确认您当前版本的 CPLD (Complex Programmable Logic Device) 在上电状态下，是否正确响应了BMC发出的“切换SFC通道”或“请求电源状态”的信号。您提到的“BMC_SFC_SEL信号没有发出切换信号”可能是一个后果，而不是根因。根因可能是CPLD没有正确反馈电源状态给BMC，导致BMC认为电源未关。
    • 软件层面：根据 Kltk Zhuyuanli 的贡献，他提到过“BIOS upgrade failed because the /bmc/kepler/Systems/1/Bios was not loaded”。请检查在升级开始时，BMC上相关的BIOS资源树是否已正确加载。查看日志中 [bios]upgrade prepare: start 之前的日志，确认是否有加载失败的记录。

  3. 进行隔离测试：

    • 下电升级测试：先将服务器完全下电（Power Off），然后再通过Web进行BIOS升级。如果下电后升级成功，则证明问题确实是由于上电状态升级失败导致。
    • CPLD对比测试：既然您提到在“其他项目相同硬件的uBMC.hpm”上正常，建议重点关注CPLD版本和配置的差异。请对比正常项目与异常项目的CPLD固件版本和逻辑设计，特别是关于电源状态、SFC通道切换和BMC交互的部分。

结论总结

  • 根因：您遇到的“升级成功但未刷新Flash”是因为升级是在服务器上电状态下进行的。系统采取了“缓存升级”策略，日志中 [bios]upgrade package: the power status is not off 的报错正是该机制的直接体现。在此模式下，系统不会进行实际的Flash写入，而是等待系统下电后生效。所以Flash内容未被改变。
  • 后续建议：
    1. 首选方案：在服务器完全下电后，重新执行BIOS升级操作。这应该能解决问题。
    2. 根本方案：定位并修复上电状态下BMC获取的“电源状态”不正确的问题。重点排查CPLD与BMC之间的电源状态信号交互逻辑，以及/bmc/kepler/Systems/1/Bios资源树的加载情况。您提到“CPLD不一样”是非常关键的线索。

power status是系统测上电状态，当前是开机状态，升级bios后会缓存bios固件，当下次下电时会开始升级bios

通过排查上电问题，确定是CPLD获取的Power Good状态一直为上电，导致没有进行Flash权限切换，实际没有操作Flash,后来将上报状态设置为掉电进行验证，烧录成功，感谢

还有个问题，网页烧录CPU BIOS时，是用的hpm文件，这种格式里包括BIOS的纯二进制文件，但是会有压缩，我怎么才能得到BIOS的二进制bin文件？这样就可以直接用flyPro烧录Flash，不用通过网页了
