	There is a way to really do hard-reset from software if you take one
of your outputs to actually assert the RESET pin. Pay attention to
follow specs, make sure it stays low long enough or whatever.

Disable interrupts, enable watchdog (if you don't use it already), loop 
forever without writing ARMCOP and wait for watchdog resetting the CPU.

Hi Maxime.

Pay attention about software reset methods and issues/limitations.
This was already discussed in this newsgroup and nothing is like a real 
power reset, or pin reset.

Please scan posted threads or wait for more feedbacks from people in the group.

Gilles

try a COP reset.
Write an non $55/$AA value to ARMCOP.
E.g.
void ResetChip(void) {
  ARMCOP= 0; // reset if COP is enabled.
}

You need a pushbutton that will force -RESET line into low state.
