Hello Sir

 
I need a technical support on Infineon controller 
which we are using in Audi project .
 
we are unable to find the value of CCNT Counter (which is always 0)
 
Controller name : TC334LP 
 CPU : CPU0_CCNT
 
Already the CPU0_CCTRL L 0x0000000002 enabled and configured .
 
Could you explain how i can get the value of the CCNT ?
 
I want to find execution time of the function .
So i have to use CCNT

Hello,

You can refer to the CPU_Perf_Counters_1_KIT_TC397_TFT example in the ADS. You need to use mfcr/mtcr for reading and writing the registers. If you still facing the issue, please share your code snippet.

Thanks.

Hello,

This is not expected. Could you also check the value returned by IfxCpu_stopCounters after execution of my_function?

Thanks.

Thanks.
