TMS320C5510 CCS: How to access memory

Hi

I'm trying to access memory on a TMS320C5510 DSK board.
As much as I understand there are 8Mbytes of memory on the DSK board
I'm using CCS and ansi C

At the moment its possible only to declare 5 type int 64x64 arrays with
out linking errors.

Is it possible to declare arrays that access those 8Mbytes of data? If
yes, how?

Best Regards and thank you

The .bss section of your linker command file (*.cmd) specifies where all the 
global/static variables should be placed.  Based on what you're desribing I 
imagine this is currently set up such that it is placing the .bss section in 
internal RAM.  By changing the linker command file such that the .bss 
section is in external RAM that will cause ALL your variables to be placed 
externally.  If you do not want to put everything external you could do a 
#pragma DATA_SECTION as described in the C Compiler Guide.

In addition, you may need to compile with the large memory model (or write
specialized asm routines to access the extended memory)

Great point!  For some reason the default project settings do not use large 
memory model..  That is good advice for anyone starting a project on CCS.
