I’ve just received a couple of Pi 3 B+ cards and tried installing FlytOS on it using the latest image from your download page. When booting it hangs at the rainbow colored screen. When googling this seems to be a known issue for the Pi3 B+ when using older boot code. How do I go about replacing the boot code?
I’m travelling today, so I won’t have access to a Pi for testing until tomorrow, but it seems like the bootloader needs to be updated for the RasPi 3B+ to work with Ubuntu according to some quite lengthy forum threads
I have got the RPi3 B+ to work now. It does not work with the official Ubuntu Mate image since it does not have the boot code necessary for the RPi3B+ as described here: https://ubuntu-mate.community/t/16-04-2-wont-boot-on-rpi-3-model-b/16210/14
However, some kind soul on the internet made an Ubuntu 16.04 Ubuntu Mate image with the updated boot available here: https://ubuntu-mate.community/t/ubuntu-mate-for-raspberry-pi-3-model-b/15867/10
Thanks for the information. I will update our documentation to reflect this change.
