Hi All,

I have RAM version of U-Boot which is running on a board similar to 
MPC8260. My memory map isas follows:

I have downloaded Linux 2.4.25 kernel image through kermit. after 
downloading the image in SDRAM location 0x30000000 and giving the command 
bootm 0x30000000

 the prompt shows a message:


TCS-PIC-UBOOT=> loadb 0x30000000## Ready for binary (kermit) download to 
0x30000000 at 57600 bps...

## Total Size      = 0x000936f6 = 603894 Bytes

   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... 

The system hangs here and is not able to uncompress the kernel any 
further. I have checked in the FAQs provided in the denx's site, but could 
not find anything similar to my case.

I would appreciate any help.

Thanks & Regards,
