I have two raspberry pi 3's that boot perfectly with raspian, but don't boot with ubuntu snappy core.
Here's what I did:
$ wget http://cdimage.ubuntu.com/ubuntu-snappy/16.04/current/ubuntu-core-16-pi3.img.xz $ sha256sum ubuntu-core-16-pi3.img.xz -> correct checksum $ xz -d ubuntu-core-16-pi3.img.xz $ dd if=ubuntu-core-16-pi3.img of=/dev/sdb
Everything seemed to work at this point. When I tried to boot the pi with the sdcard here's what happened:
- Red led turned on,
- green led blinking,
- Some messages on screen, that the pi is booting up (I could take a photo if you want to see them).
After that, the display just shows 4 raspberries. The green led is still blinking, usb mouse + keyboard have power, both lan status led's light up.
I would be thankful if anyone knows why the pi isn't booting or how to fix the problem.
I want to use the raspy to run a nextcloud cloudserver. (I think ubuntu is better than raspbian: Nextcloud is probably well testet on ubuntu, and security updates are afaik faster. Ubuntu mate worked, but the nextcloud snap package had some troubles with ubuntu mate)
