I want to use oprofile on my target, which I have the basics working (using buildroot master). However I am having two problems which I am not sure how to work around: - when trying to profile with vmlinux it fails saying objdump is not installed (which it is not). It says I can pass in the kernel range, I'm just not sure how to get it. - the app I would like to profile is stripped and I have no source on the target. I want to get more detailed call info so I assume I need to copy the collected data back onto my build machine where I can then do the analysis. Is this the correct way of doing it? Does anyone have examples of what they do. Any help much appreciated.
