Arm version of XOD

Is there a arm version of XOD in the works? I would like to use it on my Raspberry Pi 3.

Not yet. Raspberry is a full-fledged computer with fast CPU, OS, and poor peripherals. This is wildly different from microcontrollers which generally have no OS and rich peripherals. Supporting RPi will take much effort. This is possible but I can’t give any forecast regarding this feature.
