Issue Details

After modifying the CLIP on my FPGA device, when I try to compile my code I am getting the following error:

Error -61470: You must reload the DRAM declaration file. The Memory Interface DRAM declaration file has been updated on disk since its last association with this LabVIEW project. On the General page of the DRAM Properties dialog box, click Reload.

Solution

When modifying the CLIP files for an FPGA device, the DRAM declarations files need to be reloaded and updated in the LabVIEW project. This issue can also occur if the NI-FlexRIO driver is not installed which would cause missing files and project items. The following steps will show you how to reload the DRAM from the LabVIEW FPGA project and check that the associated files are in place.
  • Reloading the DRAM from the LabVIEW FPGA project
  1. From the project explorer, right-click on the DRAM, and click on Properties.​​​​​
  Right Click DRAM on the project explorer, under the FPGA target, then click on properties
  1. In the DRAM properties Dialog box, on the General page, the button with the blue cycle symbol will reload the DRAM.
Click on blue reload button
  • Check for missing files/driver
The DRAM declaration files are located within the FlexRIO folder (the path is shown in the above image). If you are getting this error and don't have the FlexRIO driver installed, or if the DRAM items don't show up properly in the project explorer, then install a compatible version of the FlexRIO device driver.
