Chuck,
SCB_AIRCR = (0x5FA << 16) | SCB_AIRCR_SYSRESETREQ; // Cause a RESET
while (1==1);
This works for me. Take a look at the #define for SCB_AIRCR.
IIRC, I had trouble with the definition of SCB_AIRCR. I originally used
the "hard" address instead of the definition as I didn't realize at the
time it was defined. It worked just fine. Later, when I found the
definition and used it, it failed. That register is one of the few that
is byte addressable.
