sbRIO-9629 not able to compile onboard CAN on FPGA (ERROR: [Synth 8-5809])

[martyRoboDes]

I was until recently able to compile my FPGA program with my onboard CAN module (CAN0) with no issues. After adding attaching an extra CAN module to the RMC connector I have been receiving a Xilinx compilation error (picture attached). I am, however, able to compile a program without the CAN0 module. The simplified test program that will not compile is:

The error I am getting:

I have tried the following links in an attempt to debug but with no luck:

•  

  sbRIO-9609 not able to compile CAN & FPGA RMC IO in the same VI?

•  

  sbrio-9628 CAN (FPGA I/O node) compile error.

• ERROR: [Synth 8-5809] in FPGA Complation

Can anyone shed some light on why this could be happening? It has been a few days of trying to debug. Thank you.

I had this issue previously but moving the CAN0 (onboard) below the RMC and Modules fixed it. I have been compiling fine for a year but all of sudden (after a LabVIEW crash) this error is back again even on known good working projects.  I saw this on the xilinx forum but have no idea how to fix it in LabVIEW and the only suggestion is what the links above say to do (move the resource in the project).

(Note: Interestingly it really is only the onboard CAN as if I replace the onboard with the CAN 0/1 from the 9853 (via RMC C Series), the project is just fine and compiles with no issues.
