Redefining memory map for Netra/Integra

Hi,

I want to change memory map in Netra SDK.

Current settings for Netra EVM are for 2GB DDR2/DDR3. My intention is to change this map for 512 MB memory (with 2 memory controllers each with 256 MB)

I want to repartition this map to assign 256MB to ARM, run VS demo for 4 D1 channel capture and display.

I want to allocate 256 MB for DSP.

Can someone please guide me which files should I change for getting this work ? Is there any documentation available for redefining memory map ?

Any help on this will be highly appreciated.

Thanks,

Sweta
