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

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]
