问题描述

需要I2C 2下升级安路cpld 0x3c，每次在升级到47%时失败，
sr相关主要配置如下：
“Chip_Cpld”: {
“Address”: 120,
“AddrWidth”: 1,
“OffsetWidth”: 1,
“WriteTmout”: 0,
“ReadTmout”: 0
},
“LogicFirmware_BCU_1”: {
“UId”: “00000001020302031825”,
“Name”: “BCU_CPLD1”,
“Manufacturer”: “Huawei”,
“Version”: “#/Accessor_LogicVerId.Value”,
“Location”: 5,
“I2CUpgradeChip”: “#/Chip_Cpld”,
“I2CUpgradeLockChip”: “#/Chip_Cpld”,
“Routes”: “#/Accessor_JtagSwitch.Value”,
“DefaultRoute”: 0,
“FirmwareRoute”: 0,
“ValidMode”: 1,
“ValidAction”: “#/Accessor_AC.Value”,
“SoftwareId”: “CPLD-BC83AMDA”

CPLD I2C 升级失败问题分析

问题概述

用户在使用 I2C 协议升级安路（Anlu）CPLD 时遇到失败问题，升级过程在 47% 进度处中断。日志显示关键错误信息为：

process.lua(84): [cpld]block_write fail: attempt to call a nil value
control.lua(205): Upgrade Cpld process failed, ret=-1

根本原因分析

错误类型定位

根据知识库和日志分析，attempt to call a nil value 是一个 Lua 脚本运行时错误，表明程序试图调用一个未定义或为 nil 的函数。这种错误通常发生在：

  1. 函数未正确加载或定义
  2. 依赖的模块或库缺失
  3. 版本兼容性问题导致 API 变更

结合上下文，该错误发生在执行 block_write 操作时，说明在调用写操作函数时出现了空值调用。

与现有案例的关联分析

此问题与知识库中【Document Chunks(DC)】引用编号为 5 和 6 的案例高度相似：

  • BCU CPLD 升级失败：同样的 process.lua(84) 行出现 block_write fail 错误
  • 升级进度模式：均在初级阶段（47%或相近）失败，表明问题出现在写入初始化阶段而非数据传输过程中
  • I2C 升级路径：均通过 I2C 接口执行升级操作

特别值得注意的是，在 DC #5 中已经明确指出：

“web 页面升级BCU CPLD 失败”，并伴随相同的 block_write fail 日志，说明此类问题是系统性的，而非个别硬件故障。

可能原因详解

1. 硬件链路问题（已验证）

尽管硬件链路不稳定可能是常见原因，但根据知识库案例 7 的分析结论：

“630版本升级失败的原因是因为硬件链路不通，330版本上升级没有报错，是因为软件没有检测这类错误，实际升级未生效。通过更换硬件，问题已解决。”

而在本案例中错误是明确抛出的 Lua 运行时异常，而非通信超时或响应错误，因此 硬件链路问题的可能性较低。

2. 固件/软件版本兼容性问题（高概率）

关键证据：

  • 知识库中提到 CpldChip Object 的 630 版本不支持 BitIO 写操作，而 930 版本才支持
  • 当前升级流程可能依赖了不存在或不完整的驱动接口

推断结论：

当前环境可能存在 OpenUBMC 或 general_hardware 组件版本过低 的情况，导致无法正确支持安路 CPLD 的 I2C 写入操作，从而在调用 block_write 时触发 nil 函数调用。

解决方案建议

:white_check_mark: 推荐解决方案：升级至兼容版本

根据知识库文档 4 中技术支持的回答：

“CpldChip 630版本还不支持，需要930版本才可以支持。”

建议立即采取以下措施：

  1. 将系统升级至包含 CpldChip 930 版本及以上的 OpenUBMC 发行版
  2. 确保 mdb_interface 仓库版本为 1.80.88 或更高
  3. 验证 general_hardware 组件版本是否满足安路 CPLD 升级需求

:warning: 补充验证步骤

  1. 确认当前软件版本：

    cat /etc/openubmc-release
opkg list-installed | grep general-hardware

  2. 检查是否存在 BitIO 支持：
    查询 /bmc/kepler/Chip/CpldChip/:Id 路径下是否有 BitIO 接口

  3. 临时规避方案（不推荐长期使用）：
    若无法立即升级版本，可尝试：

    • 增加 I2C 写入重试机制（参考 DC#3）
    • 检查并优化 I2C 总线电气特性（上拉电阻、噪声干扰等）

看下linux_kernel日志，对应时间有没有cpld的日志打印

4 
local ok, error = pcall(obj_fw.update_chip.Write, obj_fw.update_chip,
                        require'mc.context'.new(), 0, info)
if not ok then
    log:error('[cpld]block_write fail:%s', error)
    return defs.RET.ERR
end

把obj_fw.update_chip、obj_fw.update_chip.Write、info打印出来看看是不是nil

感谢回复，看了，内核没有打印
