I am trying to run Oprofile 0.9.5 on ARMv6 based target.
The CPU on target is S3C64100 a ARMv6 processor. I have compiled the kernel 2.6.21 with following config options
Oprofile 0.9.5 and libpopt was compiled. The compilation and installation went through smoothly. Have I missed any thing while compilation? Or the libpopt was incompatible with oprofile 0.9.5.
I have used following sequence of command and setup for profiling.
opcontrol --no-vmlinux --image=all --callgraph=20 --setup
The Oprofile Daemon start without any error.
After letting it run for couple of minutes, profiling was stopped.
Then dumped the data with
The result with
The opreport command gives following output
error: no sample files found: profile specification too strict ?
The kernel boot message detects the ARMv6 with following message
Oprofile: using ARMv6
The /dev/oprofile is mounted.
Your help will be highly appreciated.
