Subject: 440EPX is not booting from 1Gb/128MB NAND flash
Date: Wed, 6 Feb 2008 16:36:17 -0800	[thread overview]
Message-ID: <e9eeaac20802061636t14229054yebb41fa38dc5bffe@mail.gmail.com> (raw)

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
