<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">A little embarrassing but the problem has been solved. I was using SDK to load and run the image on my Zynq Board directly through SDK. Unbeknownst to me, SDK (even when using the RUN option instead of the DEBUG
option) still hangs both processors and requires the user to start them up manually. By flashing the RTEMS image to Flash with the Xilinx FSBL I was able to get RTEMS to properly start up and wake up both processors.

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’m attempting to get SMP running on my Zynq board and am having an issue. It would appear that during CPU Initialization CPU0 initializes and then loops through
<b>_<i>ARM</i>_Data_memory_barrier </b>waiting to receive a message from CPU1 before starting. The issue is that it would appear that it never receives the message from CPU1. I am currently able to get around this by manually waking up CPU1 through the Xilinx
SDK but am not sure why CPU1 is not automatically starting. Have I missed a step?<o:p></o:p></p>
