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
