Issue Details

When I attempt to deploy my model from VeriStand to an R-Series card I receive a timeout error on my initial deployment but when I redeploy everything runs correctly thereafter, what could be causing this to occur? 


If you are using a remote chassis you can try increasing your VeriStand gateway timeout setting or if you are using a PXIe-1085 chassis and currently have your R-Series card inserted in slots 10-18 try moving your card somewhere within slots 2-9.

From this point if you are still experiencing the same error, you transfer the FPGA IP into an FPGA Add-on Custom Device and modify the initialization sequence of the custom device to to retry opening a dynamic reference to the BIT file upon error which will force a second deployment of the BIT file. This route is not highly recommended but is a known workaround for this error.
