If it was not IDENTICAL I would not have mentioned this board.
So it is identical? Then why did you write "similar to" in the first place?
And if it's really identical I thinkt he standard MPC8260ADS code should work identical, too.
Please define "after a short while". Do you see any boot messages on the console? Do you see any messages when you do a post mortem dump of the log_buf memory? [See http://www.denx.de/twiki/bin/view/DULG/LinuxPostMortemAnalysis]
I do not see any boot messages, I can't exactly define how long it takes until the reset but it is a very short time that during this time I expected at least one line saying this is the kernel.
I repeat:

I tried removing all my code and tried again, that was the first thing I thought that maybe I crash the system. I tried again and again and the problem was the same.
You cannot make such a claim. The _symptoms_ may have been the same. The problem may have been a different one.
- Check your memory map, and the init sequence of your SDRAM [no,
I'm not going to explain this here again. Search the archives.]
Unfortunatly the archives are not searchable, otherwise that would be the first thing I would
The GMANE archive _is_ searchable.
do, could you give me some hints on what do you mean init sequence of SDRAM?
IO mean the initialization sequence that is required for the SDRAM chips. In 98% of all porting problems this is the culprit.
As for the memory map, I made sure I have RAM starting from 0x0000, I have 128Mb of RAM. The IMMR is set to 0xF0000000.
Did you read the FAQ? How about the "clocks_in_mhz" setting? Or the bd_info structure used by the Linux kernel?
