Hi William, Yes I too grep from the same and found none, but I could see the profiling works good when the version was downgraded to 1.1.0. Just added the profiling tools and oprofile from meta-Openembedded in yocto & selected oprofile from Buildroot. Found the same issue. Here is the log; root@beaglebone-yocto:~# strace operf --version execve("/usr/bin/operf", ["operf", "--version"], 0xbec3ad94 /* 15 vars */) = 0 brk(NULL) = 0x50c000 uname({sysname="Linux", nodename="beaglebone-yocto", ...}) = 0...

Hi, I too grep for the same and didn't get any way to trace this. I just build the package from Yocto (meta-openembedded) and buildroot both, which yields the same. If you go back to installing oprofile-1.1.0 everything works fine? Yes with the same build system for 1.1.0 was working good. Find the attached strace log and which operf

Oprofile fails to run on ARM iMX.6 boards
