准备工作
1、下载镜像压缩包,解压成 img
2、准备一张 sd
卡,读卡器
3、orangepi
或 bananapi
或树莓派等 arm
开发板
烧制系统到sd卡
本例将介绍在 linux
系统下。
xiao@xiao-desktop cd /dev
xiao@xiao-desktop ls
ls
命令,记录未插入 sd
卡前,dev
目录下的文件。然后再将 sd
卡放入读卡器插上电脑的 usb
插口,
再 ls
命令,对比发现 sd
卡,例如本例发现 dev
目录下多了: sdc
、sdc1
、sdc2
三个文件。
或用 fdisk -l
命令,找到 sd
卡。
清除 sd
卡分区,重新建分区:
xiao@xiao-desktop /dev $ sudo umount /dev/sdc*
xiao@xiao-desktop /dev $ sudo fdisk /dev/sdc
Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
