Help required on mpc8260 kernel boot

Hello,

I am using customs board with MPC8260 processor. I have RAM version of 
U-Boot and I am able to get U-Boot prompt when I load and run u-bbot.srec 
by TRACE32. My memory map is as follows

SDRAM start address :0x30000000  and 128MB
Flash start address: 0x00000000    and 1MB

I copied the kernel image at 0x30000000 by kermit. The load address and 
the entry point of the UImage is set at 0x34000000 and 0x34000000. At 
U-boot prompt when I run "bootm 0x30000000" . The kernel hangs with the 
message " Uncompressing Kernel Image..OK" 

My questions are

1. Is the above memory configuration is correct to run kernel from RAM 
U-boot?
2. The U-Boot documentation says that SDRAM should be at 0.  Does the 
kernel will run if SDRAM is not set to 0?
3. How can I debug where in kernel source tree it got hanged? 


Any pointer will be helpful. Thanks in advance.

One of your fellows (mail address pritha.bhattacharya@tcs.com) posted
this before, and received pretty clear hints that your  configuration
is not correct.

Also, you continue to ignore answers from the FAQs.

Please read the answers you received before, and  follow  the  advice
given.

Best regards,

Wolfgang Denk
