Comment 52 for bug 1652270

is now a bad time to say i've been apt updating for some time just fine now, my previous instructions should still be accurate:

i can confirm that

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

commented device_tree_end out and made sure device_tree_address was the correct value (0x02008000)

fixes things for me - currently booting into 1042

i note that the flash-kernel and linux-firmware-raspi2 updates recently accounted for changing the device_tree_address but neither comment or hide device_tree_end - i suspect if you worked out the correct value for this then it would also still work
