Hi,
I am trying to do Internal Hard Reset from the kernel for MPC8245 based
custom board. I tried the Machine check stop approach but it doesn't
work. I am able to successfully do from the u-boot bootloader. The
following code generates Instruction Exception at the instruction that
turns off MMU.
msr = mfmsr();
/* Interrupts and MMU off */
__asm__ __volatile__ ("mfmsr %0":"=r" (msr));
msr &= ~0x1030;
__asm__ __volatile__ ("mtmsr %0"::"r" (msr)); <--- Instruction Except
addr = 0xfff00100;
((void (*)(void)) addr) ();
If anyone has a solution to this, I would greatly appreciate it.
Thanks
Arun
