"Failed to load shared library FRC_UserProgram.out on RT target device"

[Tristan Lall]

I've been getting an error message when attempting to download code to the cRIO with LabVIEW:

LabVIEW: Failed to load shared library FRC_UserProgram.out on RT target device.

I get this error the first time I try to run the code (from RAM), and the program does not start. Upon attempting to run the code once more, it succeeds with no errors.

Any ideas on what's causing this issue?

Also—and perhaps this is related—I can't get the code to stick on the cRIO, even when setting it as the startup application in the properties of the Build Specifications tree. (The no_app DIP switch is not selected.)

(LabVIEW is at revision 8.6.1 with the latest FRC updates, cRIO image is version 20. Jaguars are configured using CAN, with latest firmware. I'm using a modified version of the non-CAN default code, with the CAN VIs inserted in place of the standard drive routines.)
