Help A Brotha Out. Error 44002 and 44004.

[SpaceCows]

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

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.

[DaveCT]

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.

Network interfaces on host:
Realtek PCIe GBE Family Controller: address: 10.52.2.5 netmask: 255.0.0.0 <--- on robot's subnet
Intel(R) Centrino(R) Advanced-N 6230: address: 10.251.20.251 netmask: 255.255.255.254
Connecting FTP @10.52.2.2

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.

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.

[Tom Line]

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.

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.

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

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?

[DaveCT]

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.

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.

[Joe Ross]

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

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.

[SpaceCows]

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.

package edu.wpi.first.wpilibj.templates;
http://www.chiefdelphi.com/forums/editpost.php?do=editpost&p=1334953
import edu.wpi.first.wpilibj.SimpleRobot;
import edu.wpi.first.wpilibj.Joystick;
import edu.wpi.first.wpilibj.Timer;
import edu.wpi.first.wpilibj.RobotDrive;

public class RobotTemplate extends SimpleRobot {
    
    RobotDrive chassis = new RobotDrive(1, 2);
    Joystick leftStick = new Joystick(1);
    Joystick rightStick = new Joystick(2);
 
    /**
     * This function is called once each time the robot enters autonomous mode.
     */
    public void autonomous() {
      chassis.setSafetyEnabled(false);
      chassis.drive(-0.5, 0.0);
      Timer.delay(2.0);
      chassis.drive(0.0, 0.0);
    }

    /**
     * This function is called once each time the robot enters operator control.
     */
    public void operatorControl() {
        chassis.setSafetyEnabled(true);
        while(isOperatorControl() && isEnabled()){
            chassis.tankDrive(leftStick, rightStick);
            Timer.delay(0.01);
        }
    }

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

[NotInControl]

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