Hi ,
I am working on MIPS32-4Kc processor.
For profiling my code i used "mfc0" instruction to get the "count"
register value.This is working well on simulator and also on Board
using JTAG, but when i try to cross-compile on run on the same Board
which is booted with Linux OS, it is giving exception
(because in user mode we don't have privilages to acess co-processor)

So how can we move from user mode to privilaged modes to run my
program.
can anyone suguest a method...

bye
Raju
