Hi all,
Finally I got the solution to reset the MPC8247 processor with help of freescale service team. I am always thankfull to them. I advice you all any support you nedded raise service request.
Supervisor previlege can be acheived by using modules.
So that you can execute the mfmsr and mtmsf asm commands.
I cleared MSR_ME and MSR_IR bits in MSR register and system got reseted automatically.
Thanks for all.
