I heard mini2440 uses at91bootstrap for primilary bootloader(http://sanket-friendlyarm.blogspot.ca/) How about my tiny6410 board? Same? thanks,
first stage bootloader tiny6410
The S3C2440 CPU on the Mini2440 does not need a bootstrap. The S3C6410 CPU on the Mini6410 or Tiny6410 comes with a so called "BL0" in its internal ROM, which is able to load a so called "BL1" from NAND or SD card. This "BL1" is a small bootstrap code, responsible to setup the SDRAM and boot anything you like after it has done its job. Read the website you mentioned again and you will see, the at91bootstrap article does not relate to the FA systems in different articles at the same website.
