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

[Zhao Hongda]

I follow these steps:
$ make zImage
$ arm-linux-objcopy -S -O binary vmlinux linux
$ gzip -vf9 linux
$ mkimage -n name -A arm -O linux -T kernel -C gzip -a a0008000 -e
a0008000 -d linux.gz linuxgz.image

then load it follow these steps:
=>loadb 0xa1000000
=>bootm 0xa1000000
## Booting image at a1000000 ...
   Image Name:   akzhd crazy
   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: inflateInit2() returned -4
GUNZIP ERROR - must RESET board to recover

please help me, thanks.
