Dear all,
I Have made some modification to the VTA and deployed it on ZCU104. They are cases where the VTA times out. My requirement is avoid this timeout and program the fpga and redeploy the classification again without throwing the error. I have to send timer() in deploy classification about the timeout condition.
Here is the error 
Traceback (most recent call last):
