Subject: [Buildroot] OT: Using oprofile
Date: Wed, 02 Nov 2011 19:35:51 +0000 [thread overview]
Message-ID: <4EB19B97.10902@carallon.com> (raw)
I know this is slightly off topic, but I assume some buildroot users
must be doing this...
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.
Will
