HI All,
Our Custom board is based on EP405GP which is not supported in current
u-boot. I have almost everything running except for the Flash interface. I
am not able to Get the Flash size correct it comes back as 32MB.Also none
of the Flash related operations work. One major difference I see in our
design is we have 2, AMD S29GL256N spansion flashes in the same Bank. I
do not see any reference board which is doing this. Number of Banks is 1
and word size is 32.
Following are the definitions
#define CFG_FLASH_CHIPS_PER_BANK 2
#define CFG_FLASH_TOTAL_BANKS 1 /* also used by
CFG_MAX_FLASH_BANKS below */
#define CFG_TOTAL_CONTIG_BANKS 1
#define CFG_FLASH_BUS_WIDTH 32
#define CFG_MAX_FLASH_BANKS CFG_FLASH_TOTAL_BANKS /* max flash banks
for rfl boards */
#define FLASH_BASE0_PRELIM CFG_FLASH_BASE /* FLASH bank #0 */
#define FLASH_BASE1_PRELIM 0 /* FLASH bank #1 */
#define CFG_MAX_FLASH_SECT 512 /* max number of sectors on one
chip */
#define CFG_FLASH_ERASE_TOUT 120000 /* Timeout for Flash Erase (in ms)
*/
#define CFG_FLASH_WRITE_TOUT 500 /* Timeout for Flash Write (in ms)
*/
#define CFG_FLASH_EMPTY_INFO /* print 'E' for empty sector on
flinfo */
#define CFG_FLASH_ADDR0 0x555
#define CFG_FLASH_ADDR1 0x2aa
// An important configuration when trying to bring the board up -RAVI..
#define CFG_FLASH_WORD_SIZE unsigned int //(32 bits = Bus width..)
Any pointers to resolve this is greatly apreciated.
Thanks,
