Running both ARM core and Microblaze Together

Question

Hi,
I want to use both arm core processor_0 and a Microblaze core.. At the moment I am running a timer interrupt on Zqnc arm and Microblaze is printing somthing using JTAG UART.
When i first run the Mircoblaze first and then ZYNQ arm core, everything works fine.
But when i run ARM core first and then Microclaze, then the ARM interupts stop. It seems like ARM core get stuck.
Can anyone help me with this?
I am using 2014.2 VIvado and SDK
Thank you

Hello,
You have a few options with regards to passing arguments between VIs running on your host and Luminary Micro board.  You would be able to use serial communication or ethernet to transfer data between your board and your PC.  You could alternatively use digital pins themselves, but this is more intensive as a custom protocol would have to be written.
As for getting the VIs to start at the same time, here are some options that you can look at ( you are not limited to these):
 - get your ARM target to wait for a tcp packet from the host machine before it starts executing its main code.  That way manually starting your host VI will activate the ARM code
 -  Try using VI Server functions on the ARM target while you are developing your code, perhaps it will send the necessary commands to the host PC to open a particular VI (it doesn't stop you from placing this function to your target)
