从官方网盘下载 CB2 卡启动固件
- 1. 登录 cubie.cc
- 2. 点击上方的“国内下载”
- 3. CubieBoard_Download/Board/CubieBoard2/Cubieboard2-20151211-EMMC-TSD/Image/Ubuntu/Linaro-server-v1.1/
- 4. 下载：linaro-server-cb2-20171113-card-hdmi-V1.1.img.7z
将卡启动固件用 dd 命令（Linux）或 win32diskimager （windows）工具写进 SD卡
- 1. Linux工具“dd”命令，要先对 SD卡进行格式化，再使用 dd 命令
- 2. Windows工具“win32”，打开软件识别到 SD卡后，选择下载的固件，直接运行即可
Windows
将SD卡插入PC，把eMMC所需文件放进 SD卡 内
