Can I use CCS profile or RTA for my board C6A8168?

CCS profile shows a message "There is no activity available for the selected debug session."

The profiler works only in the simulator, as the hardware breakpoints are very limited in hardware and the great number of them used by the profiler causes too much disruption during execution to get meaningful results.

and items in RTA menu cannot be clicked.

The RTA is only enabled when you have a BIOS-based project loaded to the target and either the symbols or the .out program are loaded to the target. Does your project have BIOS support?

If I cannot use this tools for my board, is there any other method I can use?

Ultimately you can use the clock feature (menu Run --> Clock --> Enable). Simply run to the routine you want to evaluate, double-click on the clock to reset it, set a breakpoint at the end of the routine and run the target. Keep in mind the number of clock cycles is dependent on several factors other than the CPU itself.

Hope this helps,

Hi Rafale,

     Thank you for your reply.

     Can you tell me what is the several factors? 

     I found the settings in CCS v5 (Run-->Clock-->setup), and got the dialog like below.

     It seems different with CCS v3.

     With this setting, if my routine cost 10000 clock cycles, and my CPU is 100Mhz, 

     may I say the routine will cost about 10000 * (1/100Mhz) seconds in my CPU?

     Sorry to disturb you again.

Best wishes,

wang

thanks Rafael.
