C6713 Stack allocation

Started by ratemonotonic November 3, 2008
I am using C6713 DSK . My question is can the stack be allocated in
the external RAM?

I am getting some odd behaviour (a codec receive ISR is sampling the
signal at a slower rate) when I do, which disappears when I allocate
it in the internal RAM.

I just want to varify if ppl have allocated stack in the external RAM
with out problem so I can rule it out as a possible cause.

External access is slower than internal. Maybe the processor can't keep up? If you are counting cycles to set the timing, there will certainly be a slowdown in external memory.
