Code Won't Deploy

Hello,

When I deploy the code to the Roborio I get this message.

At first glance it would seem that for some reason possibly your /home/lvuser directory on the roboRIO is inaccessible or other. I'd suggest re-image the roboRIO using the imaging tool. Something is suspicious here and this might resolve it.

If that fails and you're wanting to toubleshoot...if you are familiar with ssh and have a ssh client, could you ssh to the roborio and take a look?

ssh lvuser@roboRIO-4012.local:22

If this works, you should be sitting at a shell prompt. Do a:

ls -la /home

and

ls -la /home/lvuser

Let us know what the output of these commands are. That might prove useful in troubleshooting.

I re-imaged the roborio but i was told the frc error parsers were deleted. Could this be why the code won't load.

[bob.wolff68]

I've never heard mention of 'FRC parsers' so I can't be sure. Are you saying that during the re-imaging process, the imaging tool noted to you that the FRC parsers were deleted? Or someone else told you that the FRC parsers were deleted?

The error parsers in eclipse.

That starts to sound like an Eclipse plug-in problem to me.

Right-click on a project (left hand pane) and select 'Clean Project'
Are you able to compile code?
After compiling, on the project-pane, use the little 'triangle' to open up the 'Debug' folder ... is there a FRCUserProgram?
If so, you're able to compile for sure...that's basic toolchain validation.

Plugin - I'd suggest going back through the plugin installation on screensteps. In fact, I wonder if your auto-update might be turned off. Check the Eclipse preferences (Window->preferences in Windows) and look under 'Install/Update' - open that one up and select 'Automatic Updates' and make sure the 'Automatically find new updates and notify me' is selected. If not, select this, select 'ok' and then restart Eclipse to allow it an opportunity to check for updates. I think you can also trigger this by doing Help->CheckForUpdates.

If you're familiar with the command line, I'd still suggest the troubleshooting steps I mentioned about using ssh to look at the roboRIO directly.

Thanks,
bob
