Code not loading properly
 

I'm trying to load the built-in default code provided in the WindRiver examples. However, when I deploy it, reboot the cRIO, and try to run it, the Classmate says there's no code. It does detect the stop button and joysticks, so the Classmate doesn't seem to be the problem. I think that the code might not be deploying correctly, although there are no errors when I hit download.

I've installed all the software updates, and set the computer's IP to 10.8.40.6 (team 840), so I don't know what is going wrong...

A few things of note
- the 5V LED on the power distribution block isn't lit. Could this be the problem?
- if I try to connect from the "Remote Systems" tab, I get the following error:

Re: Code not loading properly
 

Did you re-image the cRiO after installing the LabVIEW update?

Re: Code not loading properly
 

Ya know, we had the EXACT same problem with our cRIO....


What fixed it for us was installing all the updates...but...my idea here is your IP Address/Team Number...


Because ours is 1771, it was 10.17.71.2 (for the cRIO)

I thought if you only had a 3 digit number, you put a 0 in first?

So, 10.08.40.6?

That may work, I don't know. :/

PS- Does the classmate show robot connectivity, just not code?

Re: Code not loading properly
 

Yeah, I did re-image the cRIO, but I'll try doing it again tomorrow if I can't think of anything else. And yes, there is robot communication, just no code.

I guess I'll double check the updates. Does the Driver Station update ( http://joule.ni.com/nidu/cds/view/p/lang/en/id/1535 ) need to be installed on the computer with Workbench?

(By the way, the Classmate has LabVIEW and Java preloaded but not Workbench. Is that how it's supposed to be?)

Re: Code not loading properly
 

After we re-imaged our classmate, we had to do a reboot of both classmate and cRio. Make sure that the version string is like c-2010-v19 on your classmate.

Don't forget to recompile your code after updating WindRiver. We struggled for half an hour or so because we forgot to recompile our code to use the LabView mandatory update, so we were uploading v5 code to our v19 cRio.

Another useful thing is to plug a serial cable into the cRio to get its text output. Oftentimes you can take the error text it spits out and search for it on CD to get the solution.

Re: Code not loading properly
 

How are you "deploying"? First>Download? if so, make sure the settings are correct. Go to Window>Preferences and make sure you set the team # and build file in the First Downloader section
If you are using the remote system, you don't need to reboot.

EDIT: make sure you select the OS image when remote system connecting

Re: Code not loading properly
 

So it turns out that the cRIO wasn't up to date after all. Re-imaging from v5 to v19 fixed the problems.

Re: Code not loading properly
 

I also had to re-image the cRIO a couple of times before it worked. In the end it was because I had a virus checker running and it caused the re-imaging to timeout.

Re: Code not loading properly
 

I was actually having the same issue, but even after doing all the updates I'm still having this issue! :confused:

I'm using Windriver to upload code, and everything seems to deploy properly but doesn't work... Any suggestions?

Any help would be appreciated,.. I always have to spend 3 weeks fixing programming issues for my kids, and I just want them to have the maximum time developing software for once.

Re: Code not loading properly
 

We are also having this same problem, but with labview. I have been working on it for the past two days and I got nothing. Any suggestions would be greatly appreciated.

(the chassis team keeps coming to me saying "well...we want to drive it over the bump some time.")

Re: Code not loading properly
 

After updating, did you reimage the CRio to v19 over a wired connection?
I had the same issue, but reimaging did the trick.
Apparently, the error code comes from Windriver and the CRio having different versions.

Re: Code not loading properly
 

Are you using the FIRST/Downloader or the run/debug options to load code into the robot?

Re: Code not loading properly
 

Yes, we're using the First/Download option in Windriver, and it's not giving me any errors at all... We've done all the updates, and it says it's going through properly, but everytime we hook up the robot to the driver station (last years, and this years) we get a "no code" displayed.

We're using our own development laptop to load the code onto the robot, and we're hooking the ethernet cable straight to the cRIO port one. Is this correct?

Currently, we're installing a fresh copy of all the programs onto another laptop to see if that would help, since the current computer had last years software on it too. It's worth a shot I guess... any suggestions?

*edit* A fresh install did the trick. If you installed the software on a computer that you used last year, completely uninstall it first and then do all the updates + reimaging... works like a charm. Thanks everyone!

Re: Code not loading properly
 

Team 1675 is currently having this same problem (error on trying to connect remote system and "No Robot Code" shown on driver station). We have been trying from a laptop we got this year, so all the installs are fresh.

We have used FTP to confirm that our code is actually getting into the cRIO when we deploy, so that is good.

We have tried deploying/remote system from multiple laptops so it wasn't a problem with our laptop.

We have reimaged using v19 probably 5 or 6 times.

I will try completely uninstalling and reinstalling all the development software tonight. Hopefully it will work then.

2 weeks of cRIO problems makes me a sad panda.

Re: Code not loading properly
 

Are you sure you have all updates?
and more importantly
Are you sure the WR update is installing successfully?

Re: Code not loading properly
 

We can now connect via Remote System but still get "No Robot Code"

Re: Code not loading properly
 

did you do a (right click on project)>Run Kernel task...?

Re: Code not loading properly
 

When you reimage the cRIO, make sure you select the type of software you are using. We were trying to help another team that had imaged their cRIO for LabVIEW. When we downloaded C++ code, everything looked good but we got the No Code message.

Re: Code not loading properly
 

We're use Labview. Every time we develop new code and try to deploy it or connect to the cRIO, there a error that says the vi's in the start up application will not open and will remain closed if you continue to apply and deploy. I found out the by using the 'cRIO Imaging Tool' and hitting 'Format controler', the pproblem is removed and we can deploy the code and run a drive test. But when we switch users back into the developer the same problem occurs and the cRIO needs to be re-imaged again. Running the 'cRIO imaging tool' with the format controler takes about seven minutes to finish; and ontop of that we still need to deploy and build the code which take another five to seven minutes. We seem to be spending a lot of time re-reimaging the cRIO to fix our problem. How do we fix it?:confused:

Please don't post the same question in multiple places. It won't get you answers any faster. (The C++ subforum is not a good place for a LabVIEW discussion anyway.)
