PERFORMANCE_COUNTER_BASE

[Altera_Forum]

Hi, I am following performance counter part (tutorial) ' an391 ' 

And I have a problem.  When I click &#39;build&#39; from NiosII IDE, I get below message : //// **** Incremental build of configuration Release for project performance_project ****  make -s all Compiling checksum_test.c... Compiling high_res_timestamp_performance_project.c... ../high_res_timestamp_performance_project.c: In function `main&#39;: ../high_res_timestamp_performance_project.c:132: error: `PERFORMANCE_COUNTER_BASE&#39; undeclared (first use in this function) ../high_res_timestamp_performance_project.c:132: error: (Each undeclared identifier is reported only once ../high_res_timestamp_performance_project.c:132: error: for each function it appears in.) make: *** [obj/high_res_timestamp_performance_project.o] Error 1 Build completed ////  By looking at the error lines, I can guess that `PERFORMANCE_COUNTER_BASE&#39; undeclared. So I looked up three files and I couldn&#39;t find the above anywhere. So I declare it as  # define PERFORMANCE_COUNTER_BASE 0 because the line says   /*  * Reset (initialize to zero) all section counters and the global  * counter of the performance_counter peripheral.  */  PERF_RESET (PERFORMANCE_COUNTER_BASE); <== error line   I could compile it but when I run it as hardware, It give me below lines and hanging there forever.  //  nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)   Hello from Nios II Performance Checksum Test! //  I&#39;ve tried to place the above # define PERFORMANCE_COUNTER_BASE 0 at &#39;high_res_timestamp_performance_project.c&#39; first time. and at first and &#39;checksum_test.c&#39; second time.  Both compiled but result are same. Just hanging and doesn&#39;t give me back any result. What could be a problem? I&#39;ve followed the tutorial. And it doesn&#39;t say anything about this. Am I missing something?  I am using QuartusII v5.0 with UP3 board (Cyclone EP1C6Q240C) Someone says the tutorial is for v5.1. Is that a problem?  I think it&#39;s not a major problem. It seems to be simple problem... Anybody know this problem, please help me.  YOng.

I could be going out on a limb here, but I&#39;d bet that your hardware (SoPC Builder design) doesn&#39;t have a performance counter....right???

and it must be called "performance_counter" ... check your system.h in the system library...
