You need to define an external section in a CMD file, and then use the section declaration mechanism ( in C is how I know it, using a pragma, I think ) to create the buffer in this external section.

Subject: [code-comp] Please help - writing to sdram Hi all, Im a newbie to Code composer and dsp programming as a whole. I have developed a Ultra Wideband transmitter in C++ and now as part of my Masters thesis I need to implement it on a c6416 dsk. I have managed to get all the code compiling and building fine in CCS but the problem lies with the memory allocation. I have many large arrays depending on the number of multiplexed users in the system so the on-chip memory is not sufficient. I need to be able to write to the external memory off the chip. I can see the address range for these but don't know how to assign data to this external memory. I realise this is probably a very trivial matter and easy to most but as with all things getting started is my problem. Any help would be greatly appreciated. Regards, Niall Barry
