Which config are you using?
Which version of u-boot?

I'm using 1.3.2;
Config files are in include/configs/<target>.h

For example, my include/configs/M54455EVB.h shows:

#define CFG_SDRAM_SIZE 256 /* SDRAM size in MB */


In the u-boot Makefile, that is used by the target
M54455EVB_config

Which _config are you using?

Hi Allon

I am using 1.20 i think i saw that as well can i just change it there to 128 also i guess i will need to shut of the second bank. i used the same Dram as the refrence design but i only used two in stead of four chips. i used the lowest chip select.
