Erasing FPGA Flash Memory

Problem:
How can I erase the contents of the flash memory on my FPGA board?

Solution:
If you have the NI-RIO Driver 2.1 (or later) installed on your computer, then this can be done by using the RIO Device Setup Utility. This utility can be invoked through an open LabVIEW project (8.2 or later) containing your FPGA target. Right-click on your FPGA target in the Project Explorer and select RIO Device Setup to launch this utility, as illustrated below:

Once the utility is started, click on the Erase Bitfile on Flash button to erase the contents on the flash memory on the RIO device.

If you don't have LabVIEW 8.2 (or later) but do have NI-RIO 2.1 (or later) installed, then the RIO Device Setup Utility can also be invoked through your Windows Startup Menu, by clicking on Start » Programs » National Instruments » NI RIO » RIO Device Setup Utility.

To erase the contents of the flash memory if you have an older version of the NI-RIO driver, compile an empty FPGA VI and then download its bitfile to the flash memory. Whenever a new bitfile is downloaded to the flash memory, it will first erase the previous bitfiles and then download the new one.
