Hello everybody!
First of all thanks to Wolfgang Denk and Robert Schwebel for the helpful instructions to get started with U-Boot and BDI2000.
Now, I've a new problem: When U-Boot starts I can see following outsputs through "cu", before the system stops due to a data abort. (My board: PXA250, 32MB SDRAM, 32MB Strataflash, etc.)
**************************************************** U-Boot 0.4.0 (Sep 15 2003 - 12:09:08)
U-Boot code: A1FE0000 -> A1FF5728 BSS: -> A1FF6BD4 DRAM Configuration: Bank #0: a0000000 32 MB Flash: 32 MB data abort undefined instruction undefined instruction undefined instruction ****************************************************
I put some printf-lines(beginning with GM) in the soucecode to see where the execution stops. Here, my debug-output:
**************************************************** U-Boot 0.4.0 (Sep 15 2003 - 12:23:05)

If I understand right, this exception occurs due to access to the contents of the created list. For example at the line(lists.c: ListCreate): (*list)->numItems = 0;
Why does this happen? I'm quite sure that my Flash and SDRAM are working properly. Can somebody suggest a way to workaround this problem?
Thanks. Glenson Muthedan.
