为什么TI-C2XX的CC集成环境下进行时间性能分析时,时钟CLK始终为0。
你好!
我再用C2XX的CC集成环境调试程序时,想看一看执行时间的长短。但是使能时钟,设置分析点,打开性能分析窗口,运行程序后,性能分析窗口中的时间始终为0。这是为什么。谢谢你的赐教。 |

you can not use probe point only. If you run the program, the ide does not know when to start the clock.
To run this, set the first break point to the start of the code you have interest, then set the second break point to the end of the code. Run to the first break point, reset the clock to 0, run to the second, you have the cycles used. -- make sure that you do hit the second break point, otherwise, you run to the end... |
