Help A Brotha Out. Error 44002 and 44004.
 

Quest: Req. lvl 53

Hey can some wonderful human being help us with our current predicament. We are experiencing error codes 44002 and 44004. Our code seems to be experiencing problems with the cRIO's config files, causing a lot of stuff to randomly crash. We tried re-imaging the cRIO, but that FAILEEDDD. Help us out please!!!!1

Re: Help A Brotha Out. Error 44002 and 44004.
 

I'd just like to note that your IP address seems to be set incorrectly if you are using Wi-Fi to connect to the robot.

The adapter in use should have an IP address of something like 10.52.02.XX (where XX is a number like 05 or 12) and a subnet mask of 255.0.0.0. Your configuration currently seems to be for team 25120 on your wireless card.

You should also disable the network adapter that isn't currently in use when connected to the robot.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Not a programmer, but use "[code*] / [*/code]" tags like this:

"[code]" "[*/code]" to make it less of an eyesore on people browsing the thread.

Re: Help A Brotha Out. Error 44002 and 44004.
 

These errors all indicate a network connection problem, not a cRIO config issue.

The IP address looks ok, I don't think he's trying to use the wireless interface.

The fact that they're both on the 10.x.x.x network might cause an issue depending on the netmasks/routing. I agree with the suggestion to start by disabling the interface you are not using (looks like wireless?) and see if that improves things.

Re: Help A Brotha Out. Error 44002 and 44004.
 

We aren't using wifi, we're using a local area connection. We have an ethernet cable directly connected to the modem which is connected to the cRIO. I thought I had set up the IP address correctly, I did it according to the guide.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Right, but you have a second network connection through wifi, probably to a school network or something else. Disable your wireless card while using the wired interface.

Re: Help A Brotha Out. Error 44002 and 44004.
 

If disabling the wireless doesn't help, I would try bypassing the modem (it's actually just a wireless bridge, not really a modem). Plug the Ethernet cable directly from the laptop into the cRIO. It's also worth trying a different cable. A bad/loose cable could produce these symptoms.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Okay, since disabling the wireless didn't help, I'll try exactly that. Thanks for the help so far everyone.

Re: Help A Brotha Out. Error 44002 and 44004.
 

So I'm pretty sure I have the IP set correctly, and I disabled the other network. Now it appears that I just can't connect to the FTP. Any idea what would be causing this? Is our setup not correct?

Re: Help A Brotha Out. Error 44002 and 44004.
 

You indicated in the original message that you tried imaging the cRIO and it failed. Have you been able to successfully image it since then? If not, I would try that first.

Re: Help A Brotha Out. Error 44002 and 44004.
 

We had imaged it earlier and when I went to check on it, it appears that I can't connect to the cRIO anymore. I'm going to figure out why now.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Do you have a firewall or antivirus program that is blocking the connection?

Re: Help A Brotha Out. Error 44002 and 44004.
 

It looks like you changed your computer's IP to 10.52.2.2, which is the cRIO's IP address, which is making FTP try to connect to itself. The IP was correct before. Your computer's IP should be 10.52.2.5 if you're running the FRC Driver Station.

Also, your netmask should be 255.0.0.0 though it may technically work if it's 255.255.255.0.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Ah okay, good news. We fixed the connection issue with our cRIO and rebooted our computer and everything was working. We were able to load our code on to the robot and enable Operation modes in the FRC Driver Station. Unfortunately, nothing is happening. We have the "Hello World" program from the guide written in Netbeans and the motors are not turning.

At least we have made some progress and cleaned up our wires.

The motors are put into the correct ports, in case you were wondering.

EDIT: after attempting to debug, it seems that the robot isn't ever reaching the code that tell the motors to turn the wheels

Re: Help A Brotha Out. Error 44002 and 44004.
 

What mode are you placing the robot in through the driverstation to run your test, Autonomous Teleop Practice or Test?

Re: Help A Brotha Out. Error 44002 and 44004.
 

We have tried all of them and receive the same result of nothing.

Re: Help A Brotha Out. Error 44002 and 44004.
 

I would recommend simplifying the operator control for now.

I have never used the Timer function in teleop, so this timer may be throwing your code off, but if the code is not being reached, make sure the conditions of the while loop are being satisfied. Or you could just remove the while loop entirely and see how that works.

This may or may not work for SimpleRobot, as I always use IterativeRobot.

Does the operatorControl() function run periodically?

Re: Help A Brotha Out. Error 44002 and 44004.
 

I know you've corrected the IP address problem, but I wanted to point out that those codes aren't actually errors. They're only warnings, and in many cases they just verify that the network connection is functioning as expected. (In your specific case, they actually verify that there is no network connection at all.)

So now you're getting no response from your motors? That could be the fault of a great many things. To start narrowing them down, look at some of the many status lights on your robot. When you're trying to move the motors, what are the lights on your motor controllers doing? What is the big orange Robot Signal Light doing?

Re: Help A Brotha Out. Error 44002 and 44004.
 

I'm thinking that no functions are ever reached. I removed both the timer and the while loop, both getting no results. I got this message in the console: [cRIO] Default disabled() method running, consider providing your own. I created a disabled() method in the code and I still received the same message.

Also my Jaguar motors just constantly blink yellow and my Robot Signal Light continuously blinks when the driver station is off, but it starts to change its blink pattern when I change the operation modes in the driver station.

Re: Help A Brotha Out. Error 44002 and 44004.
 

That is appropriate advice for IterativeRobot, but not SimpleRobot. In simpleRobot, operatorControl is called once. It is the users responsibility to provide a while loop and to provide a delay (to avoid pegging the CPU).

Re: Help A Brotha Out. Error 44002 and 44004.
 

Does the disabled() method show an override symbol in netbeans? If not, you've spelled or capitalized it wrong (or something similar). If it does show an override symbol, then one possible explanation is that you are not downloading the program you think you are. Is your project set as the default project in netbeans?

As described in my previous post, the while loop and timer are both necessary. Please put them back in.

Re: Help A Brotha Out. Error 44002 and 44004.
 

I put them both back in and I am getting an override symbol in netbeans for all of the functions. It is also set as the main project in netbeans and there are no other programs written, so I don't know if it could possibly download a program that I don't know about.

Keep in mind that it may not be an issue with the program at all, it may be our motor controllers which are blinking yellow, as mentioned earlier.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Please post your current program (with the disabled() method) as well as the complete netbeans output. It may be helpful to zip your entire project and post it.

If it really is printing that you haven't provided a disabled() method, even though you have, the fact that the speed controllers aren't receiving signal is another symptom, not the root cause.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Okay, that would make sense.

Here is the full code:

And here is the full console info:

Would you need the whole project in a .zip or just the .java code?

Re: Help A Brotha Out. Error 44002 and 44004.
 

The whole project

Is this the directory that your project is in?

Re: Help A Brotha Out. Error 44002 and 44004.
 

Yes the code is located in that filepath.

Re: Help A Brotha Out. Error 44002 and 44004.
 

The tighter netmask 255.255.255.0 may help discern between the robot and the schools wifi setup and it definitely will work. But at competition it must open up to 255.0.0.0 to talk to the FMS.

Re: Help A Brotha Out. Error 44002 and 44004.
 

Alright our problem has been solved. We just created a new project and copy and pasted the old code into it. I guess the filepath of the old project was messed up.
