Is the link just down or has it been removed? We have started testing the system using a Pi2 and need to recheck setup options.
Raspberry Pi and Raspberry Pi 2 are not supported hardware. We do have an un-mantained google doc that you may want to reference in the setup of your device. Please keep in mind since this hardware is not supported, we cannot assist with issues related to Rise Player on this device.
Thank you for reaching out. We installed the Linaro based image on a Pi2 for testing purposes and it has been working pretty well but we are very new to Pi, Ubuntu and Rise so any help is appreciated! We have started with a wired connect but want to get wireless going. We also try to push the boundaries of what video the P1 will support and the reliability of the Pi/Rise player. We like the small footprint.
