Hi All,

I am trying to use oprofile in Analog Device's Blackfin based system

under uClinux 2.6.22.18-ADI-2008R1.

oprofile seems to compiles fine.

When I start it:

/usr/bin/bfin_opcontrol --init

/usr/bin/bfin_opcontrol --start-daemon &

/usr/bin/bfin_opcontrol --start

/usr/bin/bfin_opcontrol --dump

In the log file I see several lines:

oprofiled: open

opreport gives me:

/usr/bin/opreport -l

/usr/bin/opreport

error: /var/lib/oprofile/samples/current/{kern}/zaptel/{dep}/{kern}/zaptel/TIMER.0.0.all.all.all:

No such device

 

Can you please give me some pointers to look at.

Thank you!
