21. ARM 服务器更新固件

更新固件可以解决lscpu显示不正确问题，如socket和cache大小。

21.3. 更新办法

查看当前固件版本

浏览器iBMC界面→系统管理→更新固件

Primary Partition Image Version :   2.45
Backup  Partition Image Version :   2.40
BIOS Version                    :   1.34
CPLD Version                    :   1.05

到服务器官网下载新版本固件，例如： 网址

需要下载iBMC，BIOS，CDLP三个压缩包。 解压后在浏览器界面

浏览器iBMC界面→系统管理→更新固件

依次上传，并点击升级，每个固件升级需要几分钟，升级成功会有提示。

升级成功后

Primary Partition Image Version :   3.22
Backup  Partition Image Version :   2.45
BIOS Version                    :   1.58
CPLD Version                    :   1.05

CPLD升级不成功，是因为服务器版本太低。
