2016 Java code not deploying

Technical Java
1

I have a demonstration tonight for STEM and the robot code will not deploy. Im using old 2015 code that I ported over to 2016 (all i had to do was change gyro to analoggyro) but it simply will not work. I have installed the update suite and updated the Eclipse plugins. Here is the output file

I have reimaged the RIO, reinstalled Java, switched batteries, everything. IPv4 settings are on automatic. I cannot figure this out. No errors in code. Sample code does not work either. Please help.

2

Maybe try setting the IPv4 settings to 10.XX.XX.5 where XXXX is your team’s number. Like 10.43.28.5 for your team.

3

Tried that. Same error. Driver station communicates with both scenarios.

4

I’m looking to see if i can reflash the 2015 image and backport my code again. I can’t find the image though.

5

I don’t know if this will help or not but…

6

Try deleting the bin, build, and dist directories for the project and then re-deploy.

7

Reinstalled java and deleted those folders. Didn’t work either. Any other suggestions?

8

Frickin just realized I’ve got the wrong version of Java on the RIO. Used HardFP instead of SoftFP. Not near the robot right now, just browsing the instructions when I saw that. Will try tomorrow and report status

9

If that doesn’t do anything, try enabling Warnings + Prints using the little gear in the DS Messages window or use RioLog in Eclipse. They may tell you your code is crashing and give you a clue why.

I’m on my way to try what I posted previously but I have enabled those before and they kept giving me bad ping and that its switched to driver station mode, it would happen 4 times and stop. I’m assuming that was it crashing and starting because this year’s image restarts on crash 4 times and then quits so that your not isn’t dead on field from one lousy command.

That was the issue. Fixed it with the correct version of java.
