Configure target board in u-boot

Beagleboard# setenv ubifsargs ‘setenv bootargs console=${console} ${optargs} root=ubi0:rootfs ubi.mtd=4 rw rootfstype=ubifs’
Beagleboard# setenv nandboot ‘echo Booting from nand …; run ubifsargs; nand read ${loadaddr} 280000 400000; bootm ${loadaddr}’
init=/init rootwait omapfb.video_mode=640x480MR-16@60'
Beagleboard# setenv optargs ‘init=/init omapdss.def_disp=dvi omapfb.mode=dvi:1024x768MR-24@60’
Beagleboard# saveenv

Flash Linux Kernel

Put kernel into SD card first partition, VFAT format. Named as "uImage.bin" (you can check HowToGetAngstromRunning as SD card as reference)

• NOTE: for Beagleboard rev B7, the kernel image name should be "uImage" instead of "uImage.bin".

Beagleboard# mmcinit
    or mmc init (depends on your u-boot)
Beagleboard# run loaduimage
Beagleboard# nand erase 280000 400000
Beagleboard# nand write ${loadaddr} 280000 400000

Flash Root File system

• untar the tarball into SD card second partition.

• If you build from scratch, rename from 'out/target/product/beagleboard/system.img' to 'android_beagle.ubi'.
• boot from SD
• flash_eraseall /dev/mtd4
• nandwrite /dev/mtd4 android-beagle.ubi
