CPU load shows nothing in SYS/BIOS

Zhao Shui

Hi，everyone!

Now I meet a strange problem,when my programs start and stop at a breakpoint,the Exec Graph works quite well,but the CPU load & thread load always show nothing.I'v already added the RTA agent to my SYS/BIOS，is there anything else that should be configured before the LOAD works?

I'm using DSK6455，and my bios version is 6.33.04.39.

Could anyone help me?Thank you very much

Hi Zhao,

I believe the Load module calculates the CPU load by calculating the amount of time it spends in the idle loop vs. some other contexts (task/swi/hwi). If you always have a task (or swi/hwi) running without having time to enter the idle loop, your CPU load percentage will be 0%.

In your exec graph, do you ever see it entering the idle task?
