You don't need to "pad" to boot file!!!
The ".org 2048" does that for you.
You just can't go over 2048 Bytes. (or you get the error I put in to warn you)
Boot.S should easily fit in the 2048 Byte limit. Boot.S is only really tight
when you are making an EEPROM image. The EEPROM image contains the NAND ECC
routines. The TS7200 does not have a NAND chip, so you don't need that code.
And it doesn't even have an EEPROM, it boot directly from NOR Flash.
If you are not getting a message that says:
waiting for '>'
found '>'
Then you failed to load the 2048 Byte boot code before the watchdog reset. The
boot code is never executed till you get this message.
Are you getting this message?
