Hi,
I am trying to boot my board which is based on Sequoia 440EPX. The
only difference between my board and the reference board is that I
have a 1 Gb NAND flash ( NAND01GW3B2A) instead of 256Mb flash present
on reference board.
In U-boot I have changed the board configuration file to reflect correct specs.
* Now the NAND chip has to be defined (no autodetection used!)
*/
#define CFG_NAND_PAGE_SIZE (2048) /* NAND chip page size */
#define CFG_NAND_BLOCK_SIZE (128 << 10) /* NAND chip block size */
#define CFG_NAND_PAGE_COUNT (64) /* NAND chip page count */
#define CFG_NAND_BAD_BLOCK_POS (5) /* Location of bad block marker */
#define CFG_NAND_4_ADDR_CYCLE /* Fourth addr used (>32MB) */
I have also changed the eeprom configuration word to
0x87788252
0x0947D010
0xA0A82358
0x0D050000
Is there any other place where some NAND configuration is defined?
Thanks
Nikhil
