Connecting to Download code in WindRiver

[ExarKun666]

Okay we looked at the programmers guide on the FIRST site, and followed the instructions to download code to the robot (wired, not wireless) and we are getting an error every time we try to connect to the cRIO, we chaged our team number in Window->Properties, and have connected the ethernet ports in several different configurations, and the error we get is:

Error connecting to 'VxWorks6x_10.24.29.2'(Registry localhost). Failed to
launch target server
Possibly caused by: Back-end not connected.

Removed dead entry from Registry!

What is the configuration of the ethernet ports? What is the problem here? TY to any who reply.

If you're connecting directly without the wireless, are you using a crossover cable and not an Ethernet cable?

[ExarKun666]

we are using ethernet... we will try crossover and see

Can you try this specific sequence of steps:
1) Start Wind River
2) Try to connect (and get the error message)
3) Leave Wind River running
4) Start the FRC cRIO Imaging Tool
5) Choose the Development Environment Wind River and Apply (don't reformat the controller)
6) Return to Wind River and try to connect again

somehow some way, which I think we accidently stumbled into, we solved all the problems, because we have been trying to download code, and been trying to get the wireless working simultaneously since the competition began, and today we got both to work, we aren't completely sure of how we accidentally found the solution, but we are glad that we did!

I remember receiving a similar or same error message and it was because we had the LabVIEW image loaded instead of the WindRiver one.

We suspect that we have the wrong version of Windriver (we think we have 3.0, but think we need 4.0) - we've downloaded the workbench updater, but it doesn't seem to update anything when we run it. It says that it's extracting to a folder that doesn't exist, and runs a command prompt for a few seconds, then closes. Our error, when we try to connect Windriver to the CRio, we get the error message "possibly caused by back-end not connected".
what IP address should our computer have? Our computer can ping the robot.

What is a crossover cable? We're using Ethernet right now. Thanks

An Ethernet jack for twisted pair wiring (pretty much the only kind of Ethernet jack you'll ever see) has specific pins defined for data out and for data in. In order to connect two normal jacks together, you have to use a cable that swaps the wires so that data out of one jack goes to data in of the other. That's a crossover cable.

Ethernet hubs and switches have "crossover" jacks, so to connect to them you use a straight-through or "patch" cable. That's the normal kind of Ethernet cable, since it's rare to connect only two devices together without a hub.

For years, most modern computers' Ethernet adapters have had the ability to automatically sense what they're connected to and swap their connections appropriately, so crossover cables are not often required. One place they are required is between the cRIO and the Axis 206 camera, because neither of those two devices will do internal crossover automatically.
