Re: [c6x] Fwd: Re: How to speed up profiling

Hi Yong,
You need to perform initialization steps for the Timer Module before you can start the module.
Also send across your code, if possible. I will try and see what is the mistake you are committing.
BTW, you needn't enable the clock. The clock is enabled through the Software only.
HTH,
Ganesh

HI, ganesh
 
Do i have to enable clock as well when using TIMER_getCount()? If i enable it, the same error message (invalid CIO command) comes out.
 
Thank you
 
Yong

Hi, Ganesh
 
My code in main()
 
Uint32 start, stop;
CSL_cfgInit();  //initialization  function generated by CDB
TIMER_start(hTimer1);
start = TIMER_getCount(hTimer1);
 
.....//other code

stop = TIMER_getCount(hTimer1);
printf("start: %d\n", start);
printf("stop: %d\n", stop);
printf("cycles: %d\n", stop - start);
 
in videocfg_c.c generated by CDB file
 
void CSL_cfgInit()
{
    hTimer1 = TIMER_open(TIMER_DEV1, TIMER_OPEN_RESET);
    TIMER_config(hTimer1, &timerCfg0);
}
 
thanks
Yong

Hi Yong,
Did you set the configuration parameters for the module properly ? Are you using the correct CSL for the chip ?
Have you set the parameters of timercfg0 correctly ?
Perform a reset timer before you config your timer i.e. TIMER_config.
Also one more important thing is that you need to multiply the difference by 8 i.e. any output from the TIMER module is scaled down by 8. You are missing the multiplication by 8.
Kindly verify the same.
Thanks and Regards,
Ganesh

Hi, Ganesh
 
I use default configuration parameters for the module , see below
 
timerCfg0
INput Clock Source(CLKSRC)              External Source
Cl;ock/Pulse Mode(CP)                          Pulse mode
Pulse Width (PWID)                                 one clock cycle
Function of TOUT(FUNC)                     General_Purse Output
  DAta Oputput(TOUT pin)                    0
  TOUT Inverter Control(INVOUT)   Uninverted
  TINP Inverter Control(INVINP)     Uninverted
Timer Operation                                       Hold
Period Value                                               0x0
Counter Value                                            0x0
Control REgister(CTL)                            0x0
Period Register(PRD)                             0x0
Counter REgister(CNT)                          0x0
 
Timer_Device1
Open Timer Device                     True
Handle                                             hTimer1
Enable Pre-INitailization        True
Pre-INitailize with                     TimerCfg0

Thanks
