Issue Details

I have been running the NI 6587 Serial Generation - Export Clock (Host).vi from the NI 6587 Serdes Connector CLIP Reference without any issue. However, recently, all of my FPGA references are showing up as invalid and the Onboard_Clock_Ready value is always false. I tried checking the value of the property with the method outlined in How do I Configure the Adapter Module Onboard Clock Frequency of an NI 6587R?, but the value stays false no matter what I do. Is there a way to reset this value manually?

Solution

The Onboard_Clock_Ready property is read-only, so you cannot overwrite this value in software. However, this issue may be caused by a corruption of your bitfile or installation of the FlexRIO driver. Loading another bitfile and then reloading the original bitfile may help resolve this. If not, a reinstallation of the FlexRIO driver should reset the onboard clock so the property will read true.
