Boot and enter BSR mode.
Power on the board to begin the boot process. Enter the root password to log in as root.
Enter Backup mode by entering the following command:
# echo mem>/sys/power/state
The system enters BSR mode.

Exit BSR and Save Snapshot Image.
Now press the nStart button on the board to exit BSR mode. The power supply restarts and the ROM boot sequence is started:
- at91bootstrap exits DDR self-refresh
- at91bootstrap analyzes memory maps and saves only the valid DRAM contents as a snapshot image

Finally, power off the board.
