problem in Booting kernel From SD card- OMAP3530

We have OMAP3530 board from Boardcon company. It is the same as EMA
DEV3530. They have given the board with preloaded boot files in NAND.
So, when we boot it from NAND , it works fine. But, when we followed
the instructions in the manual given by you and try to boot the board
from a SD card, it doesn't work. We have used the Boot files given in
the CD-ROM. Please let us know what went wrong , and suggest a
possible solution.
