I have installed Ubuntu Core Snappy (ubuntu-15.04-snappy-armhf-raspi2.img
) on a miniSD card following the [official instructions1]. Everything went fine with no error and the miniSD has 3 partitions now.
But when booting the Raspberry Pi 2 with this miniSD, I have the kernel boot messages flying on the screen and then nothing. The HDMI screen turns blue and displays "no signal".
Any clue?
I changed the USB2miniUSB cable and this time, the computer booted completely... Strange but it seems the cable I was using was of too low quality and not supplying enough power.
