Issues with JNI .so for FRC

[fsilberberg]

All of of those libraries (with the exception of libHALAthena.so) were taken directly from the roboRIO to start with. They're in a few ni locations, a find on /usr should show them.

New issue - when the JNI library is loaded, our Talons refuse to enable in auto / teleop. Any insight into this?

Do they enable but not get commands (solid yellow), or stay disabled (blinking yellow) when you switch to auto and teleop?

One thing I do wonder about is if you are using the default WPILib in addition to the custom built JNI. The default WPILib has the JNI library built into the JAR, and I wonder if the built in one is conflicting with the custom one you built. Are you modifying WPILib completely, or just trying to add something on top?

They're blinking yellow/orange (pardon my colorblindness). We're wrapping some 3rd party MXP code in JNI rather than porting it. I also suspect a conflict, but I'm not sure where it would arise.

Nevermind - found the bug in our JNI code! Had multiple calls to HALInitialize. I'll post notes on the stuff we did when I have some free time.
