Is there any way I can find out the difference between the IXDP425 board (development platform) and my customised board? I have the schematics only of my customised target platform.
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.
From the schematics its clear that the IXP425 266MHz network processor uses the 33MHz PCI bus. The Expansion bus is connected to the Flash (Boot ROM). the SDRAM used is 4M*16*2. Serial port is connected to UART1 and MII 1 to the Lan port PHY. The physical address for Flash is (0x50000000) and SDRAM (0x00000000).
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.
Do I have any changes in the /include/configs/ixdp425.h ? CFG_HZ is 3333333 currently. What r the files in U-boot i have to concentrate on? And what r the other things i have to check for considering Iam a newbie in this field.
Can it be that I havent used the right cross toolchain to compile? R there some options i have to select? I have used arm-linux-tools-20061213.tar.gz ??
Can someone please guide me.
I am.
Best regards, Stefan
