Download the uboot image: # sudo dd if=u-boot.bin of=/dev/sdx bs=1K skip=1 seek=1; sync Or If you're using no padding uboot image: # sudo dd if=u-boot-no-padding.bin of=/dev/sdx bs=1K seek=1; sync Download the boot image: # sudo dd if=boot.img of=/dev/sdx1; sync Download the android system root image: # sudo dd if=system.img of=/dev/sdx5; sync Download the android recovery image: # sudo dd if=recovery.img of=/dev/sdx2; sync |
以下是具体下载命令:
- 下载uboot映像:
$ sudo dd if=uboot_sabresd.bin of=/dev/sdb bs=1K skip=1 seek=1; sync
还有种不要skip的情况,具体看编译的uboot版本,命令参考上述资料 - 下载boot映像,就是集成kernel:
$ sudo dd if=boot.img of=/dev/sdb1; sync - 下载android 系统映像:
$ sudo dd if=system.img of=/dev/sdb5; sync - 下载android recovery image:
sudo dd if=recovery.img of=/dev/sdb2; sync
完成。
