But the function you mentioned detect that flash is not erased.

Are you using a 16bit port for data connection to the flash ?

First check i would do is an "erase" test.
 
Try to erase some sectors with "erase" command, something like

# erase 40000 4ffff

Then dump the memory, (to be sure also with BDM eventually), to see
if it has really been erased.


Also, these are some settings i am using in my config, maybe they can 
be useful:

/*
 * Start addresses for the final memory configuration
 * (Set up by the startup code)
 * Please note that CONFIG_SYS_SDRAM_BASE _must_ start at 0
 */
#define CONFIG_SYS_SDRAM_BASE           0x00000000
#define CONFIG_SYS_SDRAM_SIZE           16              /* in MB */
#define CONFIG_SYS_FLASH_BASE           0xffc00000
#define CONFIG_SYS_TEXT_BASE            0xffc00000
#define CONFIG_SYS_MAX_FLASH_BANKS      1
#define CONFIG_SYS_MAX_FLASH_SECT       1024
#define CONFIG_SYS_FLASH_ERASE_TOUT     1000


/*
 * CFI FLASH driver setup
 */
#define CONFIG_SYS_FLASH_CFI
#define CONFIG_FLASH_CFI_DRIVER
#define CONFIG_SYS_FLASH_USE_BUFFER_WRITE

Let us know if you find something.
