How to wake up cpu1 from cpu0

1. I am trying to run freeRtos LwIP application on cpu0 and interrupt based USB mass storage device application on cpu1.

2. Individually they run perfectly, but i want to wake up cpu1 from cpu0.

3. I used the application project of running baremetal on both cpu given under reference design and tutorial of zedboard, but it is not working.
so can anyone tell how to wake cpu1 from cpu0?
Any help is highly appreciated

Hello Pamela,

Xilinx has two XAPP application notes dealing with simple AMP configurations using both processors. The most recently updated is XAPP1079, which is running a 'bare metal' app on both processors but may have the best example on how to 'wake cpu1'. The wiki for XAPP1079 is here:

XAPP1079 details using Linux on CPU0 and a 'bare metal' application on CPU1. The wiki for XAPP1078 is here:
