I grabbed an iso of ubuntu 16 for raspi 3 from here: https://ubuntu-pi-flavour-maker.org/download/
I ssh'd in with ubuntu, set a password.
apt-get update && apt-get upgrade
All good so far.
Then I ran
poweroff, great, the raspi appears to powerdown... leave it a bit but the leds are still on and red.
Leave for a total of about 4 mins.. led is still solid red.
Disconnect the lan and usb, leave for a bit.
Plug the lan and then the power source back in, but this time the little guys isn't booting up, the led is just solid red with nothing else.
This post is talking about a powerswitch: How do I turn on my Raspberry Pi after shutdown?
Is there a way to boot a raspi without buying this powerswitch? It's Easter and the shops aint open till Tuesday.. :/
If you can make out the image the first main error seems to be
No FDT memory address configured. Please configure the FDT address via "fdt add " command.
Then following with
ERROR: Did not find a cmbline Flattened Device Tree
UPDATE After some further reading it seams the iso i used (https://wiki.ubuntu.com/ARM/RaspberryPi) is not supported by cononical. I am now trying the https://developer.ubuntu.com/core/get-started/raspberry-pi-2-3 version.
