Build Complete,
0 Errors, 6 Warnings, 0 Remarks.
I'm using DSP/BIOS config, like the book Rulp Chassaing "Digital
Signal Processing and Applications with the C6713 and C6416 DSK" teach
in chapter 9...

I just confuse, why there is some warning like that..
thank u for u help..
I'm very appreciate that... ^o^ Start a New Thread

Hi Krishna,

Can you show us line numbers and also what is in second.h? I copied
this source into CCS and it only got to line 133 so where are the rest
of the lines where the warnings are for?
