Hi all,

I have a customized 8548 board which has a SPASION 
S29GL064M11TFIR2, 8Mbyte, in 16-bit mode. When I 
use CFI driver, Flash is detected well and erase
operation is OK but programming failed as follows.

MPC8548E_Rev1.1=> save
Saving Environment to Flash...
Un-Protected 1 sectors
Erasing Flash...
. done
Erased 1 sectors
Writing to Flash...

After a reset, I could get:

U-Boot 1.1.4 (Nov 17 2006 - 19:36:55), Build:

It seems that ENV saving operation is OK but not
work for a big file like 600K programming. It 
just hanged there forever.

What could be the problem be? I use the CFI driver
from GIT repository on Nov. 2.

Thanks in advance,

Sam
