You mean that you tried the image and it worked on the X15? That's fantastic! We hadn't tried the board before.

What does support of the other processors entail? Is it a kernel modification? Are you sure the dsp on the Beagle doesn't work? Say hi on the gitter channel ( https://gitter.im/resin-os/chat ) and the resinOS team will be there tomorrow morning (european time) to talk more.
