Navx Mxp no longer working

We updated the firmware to the newest download and are using the latest library(v2). But no matter how we initialize the gyro or what VIs we use to read data from it, it just reads out zeros. If anyone has encountered something similar or has any ideas, we'd be very grateful!

Have you tried the Example VI? (Examples/Functions/navX Example v2.vi)
How are you initializing the navX?
Are there any errors reported by the VIs? by the processing loop (navX Library v2/IO/Internal/Z900_navX_Internal_Error.vi)?

We have tried using the example vi. Both through copying how it initializes and reads from it and by just running the project. It just read 0s both ways. We've tried initializing with ic2, spi, and serial to see if any work and we haven't had any luck. And would errors pop up or are they stored somewhere?

You would need to use navX Library v2/IO/Internal/Z900_navX_Internal_Error.vi to see if the internal loop is reporting errors. Is the Connected boolean true or false with the report of 0s? Are you able to use the desktop apps that come with the navX repo by kauailabs to read the values?

We had an issue with the NavX we purchased over the summer. It would run for a few seconds and then read all zeroes. It would only work again if we power cycled our robot. We sent it in and they are sending us back a new one. Your mileage may vary.
