Hi Gautam,
Thanks for your quickly reply!
I had already read lots of document from TI or forum post, including those links you provided, but nothing help us.
I notice that there is an information as following:
[quote user="Ki-Soo Lee"]
Also note that RTA is not officially supported when using an XDS100 emulator.

which is from this post:
http://e2e.ti.com/support/development_tools/code_composer_studio/f/81/p/130994/471307.aspx#471307
But some other people also said XDS100 can work fine to show CPU load graph in this post.
I'm using XDS100 and wondering if this is the key point of my question??
Thanks!!
Ivan
