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.
