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.
