Hello!
Thank you guys for your kind help. My SDRAM initialization was not correct. Now, having done some changes, everything seems to work smoothly except one line in devices_init() in the file common/devices.c
The execution stops at the line gd->flags |= GD_FLG_DEVINIT; /* device initialization done */
Then, sometimes a "prefetch abort" occurs, sometimes it just hangs.
When I comment this line, U-Boot runs up to the bootloader-prompt without any problem. So I hope, the line above is not a crucial one if I only have to do with the serial console. But I'm interested to know what you think about this temporary solution; am I running into problems later?
Regards. Glenson.

Sounds like memory problems. Are you sure you did your RAM initialization correct?
