[Bug 1652504] Re: Recent updates broke Ubuntu on Raspberry Pi 3

[Markus Birth]

I just got access to that Raspberry Pi 3 again. I saw that the expected
fdt address now changed to 0x02008000 in the boot script.

In the config.txt, it was set as:

# set extended DT area
device_tree_address=0x100
device_tree_end=0x8000


So I changed it to:

# set extended DT area
device_tree_address=0x2008000
device_tree_end=0x200ff00


And voilà - it works. Even the MAC address is correct now.

  Recent updates broke Ubuntu on Raspberry Pi 3

Bug description:
  Hello,
  I've been running Raspberry Pi 3 with Ubuntu as described here https://wiki.ubuntu.com/ARM/RaspberryPi

  I've installed Ubuntu 16.04 and then upgraded to 16.10 and have been
  using this setup successfully since October up until last week.
  Unfortunately one of the latest kernel updates broke the installation
  and I found out the same happened for Ubuntu 16.04 LTS - and therefore
  I can no longer run up-to-date Ubuntu installation (with updated
  kernel) on my RPI.

  I am getting this error:
  Error image is not a fdt - must reset the board to recover

  I also tried this but it didn't help me:
  https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=168838

  Now I know running Ubuntu on RPI3 this way is not officially
  supported, but since Ubuntu Snappy is supported I thought someone here
  could know what is going on.

  Thank you very much.
