Hi Friends,
  I am trying to bring up the development board which has ARM926EJS processor on it.I am trying to  port u-boot and Linux kernel on FLASH memory of the board.These are 2 development board from ST microelectronics.One has NAND Flash while the other has NOR flash

I just flashed kernel.uimg and initrd.gz.uimg to NAND device. I had to combine both the images in to kerenl.jffs2.

Now i require to Flash another board (with the same kernel.uimg and initrd.gz.uimg) which has NOR device (Memory).I learned that i need to flash both the images seperately one by one. ( not as i did with NAND in which i combine both images into kerenl.jffs2) 

  I don't understand reason behind this two different flashing mechanism. Could you please provide me information on this?
