for bsp: how to configure SDRAM and nand flash

ali fattahian
I am using mini2440. I looked at the system property of win ce 6.0 and it
is showing that the total amount of my memory is 24 MB. 
Another problem is when I want to add additional features to the images,
building image ends with error. The error is flash overlap with sdram. I
think that size of nand flash must be configured too.
If anyone has any idea about problem ,I will be very happy for his/her
reply.
