Netbeans 6.8 Ftp to cRIO communication issue

Technical Java
1

First let me start of saying this, there are two things that will not communicate to the cRIO, the first, all laptops on the network, set up with netbeans 6.8, and the classmate with netbeans 6.7.1

I should also say that on monday, the exact same setup was working, and I was able to download code for some basic joystick controll through netbeans 6.7.1 on the classmate, but not on my ubuntu 9.10 laptop running netbeans 6.8, with frc plugins, or a windows laptop with 6.8 running frc plugins (yes we did set the team number)

We have flashed the robot twice with the v19 image, from the classmate, and bear in mind that it was working perfectly one day before.

also we can login to the robot with ftp (ftp://10.20.39.2) sucessfully

now what is wrong:
on the classmate, where the code was sucessfully downloading the day before using the same (while I do know it is NOT the same, because somthing is obviously different) it will compile the code, then start downloading it to the cRIO, and it will do this (not word for word)

connnecting ftp 10.20.39.2
init
ready to RUN
crio–>
some stuff
rebooting crio 1
2

4
5
6

8
crio–>nisomthin
lots of stuff on ftp
crio–>somthing about no user supplyed robotMain()
then it dose somthing like this…
cRIO–>
cRIO–>
cRIO–>
cRIO–>
cRIO–>
cRIO–>
cRIO–>
for 5 min
then it dose somthing like this
ftp_LT_Rtimeout
then (supprisingly)
BUILD SUCESSFULL 10 min
(it is not sucessfull, because the driver station shows no code, and the program will not run, that was running the day before)

I would like to also download code from other laptops, but they all stop at
READY TO RUN after the ftp init
I can get the full output of the error on thursday, I have to go to school, and will not be able to respond till tonight

I am having a very similiar error where it hangs : waiting to connect to ota command server 10.13.40:8001. I think your using an alternate method which Id like to give a try.After your code is ready Whats your process of downloading to the cRio?

Mark,

Your issue is a bit puzzling. Make sure that your development machine has it’s firewall turned off. The later out indicates that “some” robot program is running, but is it yours? Try adding some println statements in your robot constructor, operatorcontrol, and autonomous methods to see if it’s your current program running or an older version.

Other possibilities include another team member downgrading the robot, etc?

Belly,

“waiting to connect to ota command server” indicates that you’re using an older version of the SDK.

Try updating the SDK (and the cRIO image if needed) as described here:

I don’t know much about the first error, but my team solved the “READY TO RUN” error by giving the development PC(s) a static IP address. I don’t think this is supposed to matter, but when we used DHCP it didn’t work.
