Hi:
I am trying to boot 440EPx board similar to Seqouia from NAND. NAND flash is different from Sequoia's though, it has page size 2K, sector size 128K and it's 1Gb (128MB).
I set following parameters in my <board>.h file:
#define CFG_NAND_U_BOOT_SIZE (600 << 10) /* Size of RAM U-Boot image */
/* * 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) */
but it doesn't boot.
Any suggestion? What is CFG_NAND_PAGE_COUNT anyway?
Thanks,
Leonid.
