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
