We also observed a different behavior when tftping the image to RAM and then directly executing it without copying it to flash. It seems that the flash device (EN29GL256H) is then in some a mode (maybe auto-select) which prevents it from normal read operations which doesn't allow the flash driver of the OS come up. We never saw this with our old u-boot. If there are no ideas left we will have to bisect the problem. Regards Matthias
