Hi All,

I am currently working on MIPS board. I have a 32MB RAM.

The address that is shown in uboot when i type bdinfo if 0x80000000 and size is 0x1000000(16MB).

I want to increase the size to 32 MB as board has 32 MB RAM.

Interesting Finding:

When i write any data to 0x80000000 the same data is being written into 0x81000000. Same for all address in the range (data in 0x80000000 - 0x80ffffff is same as 0x81000000 - 0x81ffffff ). It seems that there is a dual mapping .

What might be the reason?

Please help
