[quote user="Chester Gillon"]The cg_xml documentation for call_graph doesn't make it clear if the reported wcs for a C5500 device applies to the Data Stack and/or System Stack[/quote]
It only applies to the data stack. What does this mean for the system stack?
I presume you use the stack configuration the C55x cpu manual calls Dual 16-bit stack with fast return. The is the configuration set up by the vectors.asm code in the compiler RTS library. In that case, the data stack and system stack grow independently, and the system stack grows slower. If you are relying on the default stack configuration the HW uses at power up, then you use 32-bit stack with slow return. In that configuration, both the data stack and system stack grow at the same rate.
