在Android下打包uboot可識別的uramdisk:

out/host/linux-x86/bin/mkbootfs out/target/product/imx51_bbg/root | out/host/linux-x86/bin/minigzip > out/target/product/imx51_bbg/ramdisk.img

在Android下打包UBI檔案系統android_root.img,android_recovery.img:

編譯核心要編譯成uImage：

make uImage -j2 ARCH=arm CROSS_COMPILE=arm-linux-

 

產生uboot能識別的uramdisk:

~/work/android_r9/myandroid_R9/bootable/bootloader/uboot-imx/tools/mkimage  -A arm -O linux -T ramdisk -C none -a 0x70308000 -n "Android Root Filesystem" -d ./ramdisk.img ./uramdisk.img
