<br>Hai,<br> We have designed MPC8548 based AMC card. We are using u-boot-1.2.0<br>and it was up. Now we plan to boot the uboot in the EEPROM without using<br>FLASH. Is it possible to boot the uboot in the EEPROM ?. We are using
<br>AT24C64C EEPROM(64KB) and it was configured as Extended I2C addressing mode.</blockquote><div><br>

In addition to David's comments about the EEPROM being only 8K, I'm
doubtful that u-boot on the 8548 can fit even in 64k. The typical
build makes it 512k, though I think the actual code size is closer to
150K. I think 8k would require some sort of magic.<br>

IIRC, the EEPROM can contain a configuration sequence, and then a data
blob to copy somewhere, which is then executed. If you want that
to be u-boot, you'll need a bigger EEPROM. Otherwise, you need to
write a boot loader. Is there a reason you don't want to boot
from Flash? I'm not familiar with that use case.<br>
