So I have two shiny new rpi3, and I want to update my existing rpi2 devices. My OSMC was easy, just swap the SD card from the rpi2 to the rpi3 and it worked out of the box.
But how can I get my raspbian SD card working in the rpi3?
It's currently booting using the default raspbian kernel (linux-image-3.18.0-trunk-rpi2) and bootloader (raspberrypi-bootloader-nokernel), but when I swap the SD card into the rpi3 it just rainbows.
I also tried updating using rpi-update, but that didn't help either.
I'm guessing the firmware it's pulling down is rpi2-only. Anyone know how I can get the rpi3 kernel/firmware while booted to a raspberry pi 2?
