Are there any errors being displayed in the Diagnostic tab on the Driver Station? If that doesn’t point you in a useful direction, use the new “#” tab to see what your CPU usage and packet times are. That might give you a clue.
I couldn’t help but notice that after reimaging the classmate, I no longer have a shortcut to the imaging tool on the desktop. Where is the file? I assume it’s somewhere in %program files%/National Instruments, but that’s too big a folder to look through.
After imaging the Classmate you need to install the FRC Tools from the NI USB key (or full LabVIEW install if you choose).
Then install the Utilities Update and Driver Station Update (plus the update for the language of your choice if you are doing development on the Classmate). After installing these updates, go to Start>>All Programs>>National Instruments>>Labview 2012 to find the Imaging Tool
Each language installs the image in a specific location. You have three options:
1.Set up Java on your Classmate
Image the cRIO form the machine you plan to program on
The kickoff images are all v43 so you should be able to image it with LabVIEW selected, wait for it to complete, and redetect the cRIO, then change the language to Java without checking the reformat box and then click Apply.
