Since Arduino and Teensyduino(PJRC) now has a release of Arduino for Arm processors, I thought I would try it out on my different ODroid processors. It works fine on my Odroid C1+ as well as Xu4.
However it does not run on my Odroid C2 which is a 64 bit Arm processor currently running Ubuntu 16.04 (64 bit)
It downloads, but when I try to launch it, Java fails.

I tried a suggestion from Paul of PJRC to remove the downloaded Java and run it with Java installed on Odroid and it also fails:

For the fun of it, I have now downloaded the sources onto my C2 and tried doing a build. Unless I tell it it's platform it fails. ( ant clean dist -Dplatform=linuxarm )
Run also fails not finding platform.
Wonder if I should try hacking the build.xml file and maybe try to find everywhere that talks about linuxarm and add something like linuxarm64, which does the same, except set arch-bits to 64...
Other suggestions?
of you coming back. I know the feeling to have to know the answer and make something work.
