In order to make Angstrom Image:
1) Insert the sd card in the computer and unmount it auto-mounted
$ sudo umount /dev/sdb
2) Zero out the SD card
$ sudo dd if=/dev/zero of=/dev/sdb bs=822906
3) Start fdisk, and partition
$ sudo fdisk /dev/sdb

The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.

4) Format the partitions
$ sudo mkfs.msdos -F 32 /dev/sdc1 -n Beagle_Boot

   $ sudo mkfs.ext3 -L Angstrom_Demo /dev/sdc2

5) Unplug, and replug in your SD card, and it should now automount the two partitions that you created.
6) Copy files in the Beagle_Boot partition
   $ sudo cp MLO /media/card/
      $ sudo cp u-boot.bin /media/card/
      $ sudo cp uImage-2.6.29-r47-beagleboard.bin /media/card/uImage
      $ sudo cp x-load.bin.ift /media/card/
7) Untar the file system
   $ sudo tar -xvjf /media/Angstrom_Demo/Angstrom...bz2
8) Unmount the partitions
   $ sudo umount /dev/sdb1
      $ sudo umount /dev/sdb2

Running the demo:
1) start a terminal program: Minicom or Tera Term
2) insert the SD card in the beagle board
3) power on the beagle board
4) stop the auto-boot by pressing Enter
5) type the below commands

mmcinit
fatload mmc 0 0x80200000 x-load.bin.ift
nandecc hw
nand erase 0 80000
nand write.i 0x80200000 0 80000

6) Set the Environment

setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait omapfb.mode=dvi:1024x768MR-16@60'
  FOR PICO: setenv bootargs 'console=ttyS2,115200n8 console=tty0 root=/dev/mmcblk0p2 rootfstype=ext3 rootwait omapfb.mode=dvi:640x480MR-16@60'
setenv bootcmd 'mmcinit; fatload mmc 0 0x80300000 uImage; bootm 0x80300000'
saveenv

7) Boot the SD card
boot
