[U-Boot-Users] for help about boot linux kernel on ep7312 board

[wizshow at xinhuanet.com]

Hi,all:

I have a EP7312 board: 
flash: Intel: 28F320J3
DRAM: 0xc0000000--0xc1000000
without a ethnet nic.

I can run u-boot 0.30 on the board .
I download the linux kernel to 0xc0500000 using JTAG(TRACE32ICD),then run iminfo:

EP7312 # imi
## Checking Image at c0500000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    344968 Bytes = 336.9 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK

Then bootm it:

EP7312 # bootm 0xc0500000
## Booting image at c0500000 ...
   Image Name:
   Image Type:   ARM Linux Kernel Image (gzip compressed)
   Data Size:    344968 Bytes = 336.9 kB
   Load Address: 00000000
   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

Starting kernel ...

IT HANGS! 

The linux kernel is OK, i have run it happily without u-boot to boot it.

Any suggestion is appreciated!

thanks.
