Re: Jetson comm to RoboRIO

OK, if I manually chmod the /home/lvuser directory to 0777, then the new plug-ins work.

Re: Permission denied when pushing code

Re: I2C working on RoboRIO
There shouldn't be. But, I haven't revisited this with the 2016 WPILib as of yet. If it works out of the box, please post that so others will benefit as well.
Thanks,
