Again thanks for your reply , the board we are using is Nitrogen 6X ,now
the size of our uncompressed file is 4.2MB and compressed is 1.8 MB , the
RAM base address of our board is 0x10000000 and  RAM size is 0x40000000 ,
we tried booting by assigning  load address as 0x10001000
 and the entry point as 10001000 and tftp 0x10800000 . We are stuck at
starting kernel

Bytes transferred = 1829585 (1bead1 hex)

U-Boot > bootm
## Booting kernel from Legacy Image at 10800000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    1829521 Bytes = 1.7 MiB
   Load Address: 10001000
   Entry Point:  10005d70
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

Starting kernel ...


Any Idea what the problem is ?
