镜像替换

镜像准备

升级uboot

镜像升级，主要参考《广东龙芯2k0300蜂鸟板快速使用指南-v1.0.240725》的1.7.1节进行

• 1 将镜像放到U盘根目录下的update目录
• 2 U盘插入板子，重启，按m进入uboot控制菜单
  
• 3 再选择通过usb升级
  
• 4 显示升级成功
  

对比升级前与升级后

替换内核

uname -a

镜像升级，主要参考《广东龙芯2k0300蜂鸟板快速使用指南-v1.0.240725》的1.7.1节进行，其实本质是将uImage放到根文件系统的boot目录下

• 1 将镜像放到U盘根目录下的update目录
• 2 U盘插入板子，重启，按m进入uboot控制菜单
• 
• 3 再选择通过usb升级
• 4 显示升级成功

对比升级前与升级后

替换根文件系统

镜像升级，主要参考《广东龙芯2k0300蜂鸟板快速使用指南-v1.0.240725》的1.4.1节进行

• 1 将镜像放到U盘根目录下的update目录
• 2 U盘插入板子，重启，按m进入uboot控制菜单
• 3 再选择通过usb升级![QQ_1723371162676.png]
• 4 显示升级成功![QQ_1723371443719.png]
