You should be able to get the schematics for the Intel eval board from the 
Intel. If it's not available on the web-page, then you should contact your 
Intel distributor/FAE.

I suspect that you have a problem either with the boot-flash setup or the 
SDRAM configuration. Here the setup from the ixdp425.h config file:

/*
 * Expansion bus settings
 */
#define CFG_EXP_CS0				0xbcd23c42

/*
 * SDRAM settings
 */
#define CFG_SDR_CONFIG		0xd
#define CFG_SDR_MODE_CONFIG	0x1
#define CFG_SDRAM_REFRESH_CNT 	0x81a

Please check if this exactly matches your setup. If not you have to change 
these values accordingly.

I am.
