[U-Boot-Users] Intel Flash CFI initialisation failure

[Mirek23]

Dear All,

            I am having the problem with Intel Flash TE28F640 J3C120 on my
avnet evaluation board
(xilinx based with Virtex-4). I have compiled successfully u-boot-1.2.0 and
it run well without FLASH support. Eventually I want to store u-boot in
Flash but when I compile u-boot with Flash support the u-boot fails during
Flash initialization.

My Flash memory is:
type:    TE28F640 J3C120 
(http://www.datasheets.org.uk/datasheet.php?article=3266188) 
vendor: Intel
spec:    NOR FLASH 64 Blocks 64 Mbits x8/x16
 

To support Flash memory I have configured u-boot with the following
settings:
#define CFG_FLASH_BASE                     0xFF800000              
#define CFG_MAX_FLASH_BANKS            1 
#define CFG_MAX_FLASH_SECT              64
#define CFG_FLASH_CFI                        1 
#define CFG_FLASH_CFI_DRIVER             1 
 
The u-boot was compiled successfully but when I booted it I have got the 
error messages when it came to the Flash initialization:

Does anybody have an idea what could be wrong?
