Hi Texblues,

the problem could be due to different things.

One thing you should definitely check is the setting "optimize for size" in "menuconfig". You mustn't turn on this option. My Board didn't start at all with this setting on.

8MB of SDRAM should be enough. I have also 8MB and my uncompressed image is about 3MB. But as I see your compressed image is that big. I don't know how you made it so big. But this is probably not the problem.

Have you checked the uncompressed image "vmlinux". It is located in uClinux-dist/linux-2.6.x/.

If this image works than it is likely a problem with the offset. Apart from that your problem could be the "optimize for size" setting.
