Hi !
I tried ts-preboot-ts9.bin (which is of 2K) &
transferd it to EEPROM via serial blaster utility.
But, after this file got tranfered, message like
"Success:.." came & further transmission of
redboot.bin file is stopped. 
I mean when I was transfering the EEPROM image of
serial blaster utility , it transfers 'boot.bin' file
in EEPROM & 'redboot.bin' file in Flash. 
but ,when I m tranfering 'preboot-ts9.bin' file( from
ftp://ftp.embeddedarm.com.images/) , it transfers only
'preboot-ts9.bin' file. & after transfering, I m not
getting 'RedBoot' prompt on terminal.
So , can u please tell me what could be the promblem?

boot images are here:

ftp://ftp.embeddedarm.com/images/

You want the appropriate 
preboot image
Should be 2KB.
