¶ 将镜像安装到 SD 卡
Windows PC
使用 balenaEtcher 安装镜像。
balenaEtcher 是 Balena 开发的开源图形化烧录工具，可将操作系统镜像写入 SD 卡或 USB 存储设备。
-
单击“Flash from file”选择镜像。
-
单击“Select target”选择目标设备。
-
单击“Flash!”开始烧录。
Linux PC
有两种方法供您选择。
-
在 Linux 上使用 dd 命令写入镜像。如果系统自动挂载了 SD 卡设备 /dev/sdX 的分区，请先卸载。bpi-copy 实际执行的操作与此 dd 命令相同。
$ sudo apt-get install pv unzip $ sudo unzip -p xxx-bpi-m2-ultra-xxx.img.zip | pv | dd of=/dev/sdX bs=10M status=noxfer -
在 Linux 上使用 bpi-tools 安装镜像：将 SD 卡插入 Linux PC，然后执行以下命令。
$ sudo apt-get install pv unzip $ sudo bpi-copy xxx-bpi-m2-ultra-xxx.img.zip /dev/sdX
¶ 将镜像安装到 eMMC
-
将 SD 卡插入 M8 并启动。
-
将待烧录镜像保存到 U 盘，然后将 U 盘连接到 M8。
-
使用 lsblk 命令查询 USB 设备。

使用 mount 命令挂载 U 盘，并进入存放镜像的目录。

使用 dd 命令烧录镜像。
root@bananapim8:/mnt/M8# ls Bananapi-Armbian_26.05.0-trunk_Bananapim8_bookworm_legacy_5.15.147_xfce_desktop.img root@bananapim8:/mnt/M8# dd if=Bananapi-Armbian_26.05.0-trunk_Bananapim8_bookworm_legacy_5.15.147_xfce_desktop.img of=/dev/mmcblk1 输入了 10723328+0 块记录 输出了 10723328+0 块记录 5490343936 字节 (5.5 GB, 5.1 GiB) 已复制，240.847 s，22.8 MB/s -
取出 SD 卡，再次为 M8 上电，即可从 eMMC 启动。
