Issue Details

I have a LabVIEW FPGA VI that I cannot deploy to my Ethernet RIO after compiling because I receive the following error popup window. 


The FPGA may already have a bitfile running on it. You can prevent this file from being loading with the Disable FPGA Startup App setting. You can complete the following steps to configure the Ethernet RIO startup options in MAX.
  1.  In MAX, expand your system under Remote Systems.
  2. Select the Startup Settings tab to configure the startup settings.
After changing the RIO's setting, power-cycle the chassis and attempt to deploy the FPGA VI again.
