The problem is fixed for me. I did some tests with a fresh installation on a rpi3 with the image from https://wiki.ubuntu.com/ARM/RaspberryPi. The image did not boot after a simple apt-get update && apt-get upgrade. The kernel was not updated, still version 1009 from the image.
The uboot error was: ## Executing script at 02000000 libfdt fdt_check_header(): FDT_ERR_BADMAGIC No FDT memory address configured. Please configure the FDT address via "fdt addr <address>" command. Aborting! reading vmlinuz 6594336 bytes read in 952 ms (6.6 MiB/s) reading initrd.img 9744755 bytes read in 1402 ms (6.6 MiB/s) Kernel image @ 0x1000000 [ 0x000000 - 0x649f20 ] ERROR: Did not find a cmdline Flattened Device Tree Could not find a valid device tree SCRIPT FAILED: continuing... To fix the uboot error, you have to change the config.txt lines: # set extended DT area #device_tree_address=0x100 #device_tree_end=0x8000 device_tree_address=0x02008000 I changed the device_tree_address and commented out the device_tree_end. The address is the same that was changed in the file /usr/share/flash- kernel/bootscript/bootscr.rpi3 from flash-kernel package from ppa ::ubuntu-raspi2/ppa-rpi3 With this changes made to config.txt I did the apt-get dist-upgrade to get the latest kernel (version 1040) and rebooted. The rpi3 started without any problems, running kernel 1040! maybe Ryan can add some script magic to the flash-kernel package to change the config.txt during the update? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1652270 Title: Could not boot into RPi3 with kernel 4.4.0-1038-raspi2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1652270/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
