Question cRIO Connection Failure
We're having some problems deploying code to the cRIO. Other people have had this problem before by the looks of some googling, but I think we tried all the traditional fixes, such as disabling firewalls, checking IP address, and went as far as uninstalling our antivirus in attempt to fix the connection issue. The cRIO port is lit green, as it should be when tethered to the cRIO. Any help would be greatly appreciated. The following is the error message we get whenever clicking the run button in NetBeans.

Code:
ant -f C:\\Users\\gcgh\\Documents\\NetBeansProjects\\RobotTemplate deploy run

Re: cRIO Connection Failure
We've seen the same exception before as well. Generally when it's happened to me it's that NetBeans is configured for the wrong team number, the firewall is blocking the connection, there's a problem with the ip settings on the development computer.

It looks like NetBeans is set up right and you said that you tried disabling the firewall (maybe double check that you turned it off on both public and private networks). You could also let the driver station set up your ip for you by hitting the "Choose NIC" button under setup. Also, did you image your cRIO, was there an error during that possibly?

Re: cRIO Connection Failure
We tried the IP fixes suggested and it's not working. We tried to re-image and the tool wouldn't even pick up the existence of the module. Something may also be wrong with safe mode-that kind of reboot won't fix it. One of our mentors is convinced the cRIO is corrupted and says we need to remove the software from it entirely. If that is indeed the case, then how do we fix it?

Why is 10.105.255.249 replying? Something is very much wrong with the network setup.

Re: cRIO Connection Failure
Did you Disable the laptop's wireless NIC and all other NICs leaving the Ethernet port the only Enabled one?
If the wireless NIC is active the tool may get confused and try to use that instead of the wired Ethernet port. It's possible the wireless is connecting to a school router running a 10. network.

Re: cRIO Connection Failure
Disconnected from wi-fi, no different. The cRIO imaging tool is not detecting any modules, despite the fact that there are three installed(This is an older style which has room for 8 modules if that matters.)

Code:
C:\Users\gcgh>tracert 10.32.44.2
Tracing route to 10.32.44.2 over a maximum of 30 hops
   1   gcgh02 [10.32.44.6]   reports: Destination host unreachable.
Trace complete.
C:\Users\gcgh>
Edit: also pinged again with wi-fi disconnected. Command prompt said pinging 10.32.44.2 but got a reply fro 10.32.44.6. (The computers IP) Sent 4 packets but lost none.

Try to IP Reset the cRIO and then re-image it.

Has it ever worked?

Try connecting your computer directly to the cRIO with a crossover (orange) lan cable, plugged into the cRIO's LAN port, so there's no switch/bridge in the data path. As was mentioned before, disable WiFi on your computer (not just disconnect any connection, go to Control Panel => Networking and disable WiFi). Your computer's LAN IP address should be 10.32.44.5. Then run the NI imaging tool and let us know what happens.

If you did find a solution please post so others with the same problem benefit! Thanks!

Re: cRIO Connection Failure
We switched pc's and we were able to reboot the cRIO in safe mode, and reformat it from there. We called National Instruments support number (check their website if you need it.) and they walked us through debugging. They wound up having us change a few things within cRIO FTP server. After that we were still having problems with getting the cRIO to respond. It turned out there was a problem with the digital sidecar because one of the ports went bad. We moved a PWM cable, then both sides of tank drive started to respond .

Thank you all for the help!
