Hi,

I am new to Oprofile . 
I used Oprofile for profling Cortex-A9 .
I getting followings Output :

WARNING! The OProfile kernel driver reports sample buffer overflows.
Such overflows can result in incorrect sample attribution, invalid sample
files and other symptoms.  See the oprofiled.log for details.
You should adjust your sampling frequency to eliminate (or at least minimize)
these overflows.
error: no sample files found: profile specification too strict ?

I am using OProfile 0.9.7 .

Please let me know what I am doing wrong here .
How I am able to get Opreport ?


Thanks
