Starting Second Core on MPC5676R

Hello,

 

I've been playing around with the MPC5676R for the last couple days. I can get to blinky on the first core without any problem, but the second I try to run the same code on the second core nothing happens.  I'm running the default project that Codewarrior creates when you start a bareboard MPC5676R project, with some added code to blink an LED, which is on GPIO 253.  I'm doing all the same initialization that I was doing on core 0, but core 1 does not seem to want to play ball.

 

The project adds this to start the second core:

 

SIU.RSTVEC1.B.RSTVEC = (unsigned long)__start_p1;

 

Is there anything else I need to do to get the second core going?  The Application Notes don't seem to mention anything else.

 

Any help is very much appreciated

 

Thanks!
