To cite the basics:
The Raspberry Pi 2 V1.2 was upgraded to a Broadcom BCM2837 SoC with a 1.2 GHz 64-bit quad-core ARM Cortex-A53 processor,[25]](https://en.wikipedia.org/wiki/Raspberry_Pi#cite_note-:0-25) the same SoC which is used on the Raspberry Pi 3, but underclocked (by default) to the same 900 MHz CPU clock speed as the V1.1.

Is there an (aarch64) image that will boot in the v1.2? Does TW support the CSI cam modules (e.g. via motion software)?
Had a look here
https://en.opensuse.org/HCL:Raspberry_Pi2
but there is only a cryptic hint for USB-booting the v1.2.
