Motor Chatter with Tynergy motors and older ESC




We are running a 2.6 and just upgraded to the Tynergy Motors. We have the older EZRun, 18A ESC units. We were doing OK until the IMU went out. We disabled it in the software and now we are getting severe chatter on the vertical thruster. It is not the motor, it is related to the ESC.

Has anyone seen this problem ?



Sounds like you are using an older version of the firmware. Have you upgraded to the 30.0.3 image? We made a number of fixes that targeted the IMU and motor chatter in that release.


Here is a link to the directions for the software update. You will need to update the image on the BeagleBone Black, as well as the firmware image on the Arduino. This guide walks through all the steps.

Please let us know if this solves the problem you are seeing.
