Reg:Oprofile :Kernel support not available, missing opcontrol --init as root ?

[manoj r. <man...@gm...>]

Hi Sir
Iam working on cross compiling oprofile to arm target device.
Iam able to compile without ant issues with configure options
    ./configure --host=$(TGT_CPU) --prefix=$(CUR_DIR)/lib/oprofile
--with-kernel-support
Iam using 2.6 kernel changes profiling  flags to y on kernel.config.
After comipiling i copied binaries to target device .
When run
 opcontrol --no-vmlinux
Iam getting this
mount: mounting nodev on /dev/oprofile failed: Device or resource busy
Kernel support not available, missing opcontrol --init as root ?

Kindly help wat else i have to do for oprofile to run without any issues

Thanks in advance
Manoj
