Enable DSPLink tracing in DVSDK

Hi,

This is what I did to enable DSPLink tracing in my DVSDK installation, but nothing more is printf'ed from my program

1. go into dsplink/config/bin directory 
2. run "perl dsplinkcfg.pl --... --trace==1"
3. 
4. go to the DVSDK root and run "make components"
5. DSPLink is built.
6. 
7. in my application, do "make clean" and "make" and I can see it is linked to the dsplib.lib just built.
8. Transfer to my target, but nothing more if printed on the terminal.

Thanks
