Please help. I am trying to boot my system using a fairly large ramdisk (~24MB uncompressed, ~8MB compressed). I can tftp it up to my board fine, and can run imi, and it says the checksum is ok, but whenever I try to boot I get the following error:

=> tftp 400000 uRamdisk Speed: 100, full duplex Using MOTO ENET0 device TFTP from server 192.168.123.254; our IP address is 192.168.123.1 Filename 'uRamdisk'. Load address: 0x400000 Loading:

Is it too large of a ramdisk? If so, what is the maximum size allowed. I have 256MB of DDR SDRAM. This is a custom MPC8540 sytem.

Thanks, Jeff Stevens
