# Script Version 1.2
|
||||
Release Note:
|
||||
1.[新增功能]支持写入板卡FRU
|
||||
2.[功能优化]修复一些交互类bug,增强脚本健壮性
|
||||
3.[功能优化]更便捷的支持脚本传感器名称本地化
|

|
||||
# Script Version 1.1 20240912
|
||||
Release Note:
|
||||
1.添加根据服务器类型适配 pcie slot 和 i2c对应关系的接口。当前可应用的服务器, 5280M7,5468M7.
|
||||
2.添加debug模式, 当启用debug模式时, 不会执行选通9641和9548的操作,仅执行读取传感器的操作
|
||||
3.考虑到读取寄存器时可能也会操作fpga芯片, 为防止混淆, 修改命令cpld, 名称更改为 chip
|
||||
1.[新增功能]添加根据服务器类型适配 pcie slot 和 i2c对应关系的接口逻辑。当前可应用的服务器, 5280M7,5468M7.
|
||||
2.[新增功能]添加debug模式,通过修改变量启用debug模式:
|
||||
2.1 debug模式下, 不会执行选通9641和9548的操作,仅执行读取传感器的操作
|
||||
2.2 debug模式下, 执行detect操作仅会针对当前配置的I2C bus进行一次detect
|
||||
3.[功能优化]考虑到读取寄存器时可能也会操作fpga芯片, 为防止混淆, 修改命令cpld, 名称更改为 chip
