No cRIO communication

[Itamar]

Hello!
Yesterday our cRIO worked just fine. Tonight we switched the two Jaguars to two Victors. Now we can't seem to get the Driver Station to communicate with the robot. We tried disconnecting the PWM cables but still there's nothing. Here's a print screen of the Driver Station:



Our PC is connected with an ethernet wire to the access point.

What can cause this behaviour?

Thanks!

That looks like your cRIO is running, but it doesn't have an image on it.

Check the status lights on the cRIO itself to see what they are showing.

You can get more information by starting Netconsole

Start->All Programs->Netconsole for cRIO

Then resetting the cRIO and seeing what messages come up on Netconsole.

When the robot is turned on the power light is on.
The status light turns on after a few seconds and then turns off.
The NetConsole screen stays blank when we turn on the robot...

I'm pretty the certain the cRIO has an image on it, it worked just fine a few days ago. What's more concerning is when I run the imaging tool it doesn't find the cRIO..

The cRIO has an image if the status light stays out (it blinks if there's an image problem).

I forgot to mention that Netconsole had to have been checked in the cRIO Imaging Tool to get it onto the cRIO, but if the Imaging Tool can't find the cRIO anyway then it doesn't matter.

I'd check your Network interfaces. Do the standard turn off all but the one you're using for the cRIO. Check that one for extra IP addresses under Advanced (on the same window were you see the IP address). Firewalls are off and all that.

Turning off the firewall did the trick, thank you very much!!!
