Just got 2 new Raspberry Pi 2s unpacked and flashed the image of our application to SD cards and oops - none of that 2 are booting resin. Instead they flash green LED - 4 long blinks then 4 short blinks, small pause and then again.
At the same time both Rpis are booting from the same SD cards if I flash them with raspbian jessie lite from raspberry website. What can it be?
Both boards are Raspberry Pi 2 Model B V1.2
