Hello,
Today, we just installed a new satellite with 1.05 image, on a Rpi 2 B, but it didn't start, it kept locked on the rainbow boot screen.
After some attempts to swap components, we took the SD card and put it in another satellite (Rpi model 2 B v1.1), and everything's ok on this one, so this is not a SD problem.
Since some weeks (?), there is a new Rpi 2 version (v1.2)
"which contains a quad-core ARM Cortex-A53 processor" instead of the Cortex-A7 and it seems that it's not compatible with the last satellite ccrma image available.

Best
