[U-Boot-Users] Why my image isn't boot?

[Zhao Hongda <zhaohd@vis.cs.tsinghua.edu.cn>]

Thanks for your help,
But when I follow your step, after bootm, u-boot complain that :

=> loadb 0xa0008000
## Ready for binary (kermit) download to 0xA0008000 at 115200 bps...
## Total Size      = 0x000c14aa = 791722 Bytes
## Start Addr      = 0xA0008000
=> bootm 0xa0008000
## Booting image at a0008000 ...
   Image Name:   U-boot Linux
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    791658 Bytes = 773.1 kB
   Load Address: a0008000
   Entry Point:  a0008000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... Error: inflate() returned -3
GUNZIP ERROR - must RESET board to recover
reseting ...

what should I do?
                                                    Hongda Zhao
