Description Lutz Jänicke 2003-03-31 13:31:41 UTC 
Description of problem:
The SDRAM size of the IXDP425 Evaluation Board is 128MByte instead of the
256MByte currently configured, see hal/arm/xscale/ixdp425/current/include/ixdp425.h:

#define SDRAM_SIZE                         0x10000000  // 256MB

Comment 1 Mark Salter 2003-04-02 00:35:48 UTC 
http://developer.intel.com/design/network/products/npfamily/ixdp425.htm
shows that the board has 256MB. My board has 256MB. Is there a 128MB
model? Are all four SDRAM positions populated on your board? In any
case, if there are 128MByte boards out there, some runtime code to size
memory would be nice. I can't do it, though as I don't have a 128MByte
board.
Comment 2 Lutz Jänicke 2003-04-02 10:17:41 UTC 
I studied once more the documentation.
My value (128MB) was around since the very first preliminary software version we
received from Intel. This has long since been corrected but never made it to our
files.
256MB and therefore Redboot is correct.

Sorry for any confusion caused,
       Lutz
