Controlling Ws2811 using Udoo
Two things. First:


  UDOO is an open hardware, low-cost computer equipped with an ARM i.MX6 Freescale processor for Android and Linux, alongside Arduino DUE’s ARM SAM3X, both CPU integrated on the same board!


The UDOO uses a ARM SAM3X for the arduino part. The Arduino Uno uses an ATMega328. Different registers, different features. A library for one won't always work on the other without modifying.

Second: The UDOO's Arduino part is 3.3v level, not 5v like the (standard) Uno. And the WS2811 does not work well or at all at 3.3v. You need to power the WS2811's off 5v, and use a level shifter for the data pin, to protect the UDOO.
