I have problem booting Linux 3.16.1. I have compiled sources from http://www.kernel.org with at91sam9263_defconfig.
I have added Flattened Device Tree support in Boot options. Followin tips suggested in this (https://www.slideshare.net/softpapa/device-tree-support-on-arm-linux-8930303) presentation to turn on Support device tree in /proc but i don't have that option in menuconfig.
I have U-Boot bootloader version 2014.10rc2 which supports device tree. I have generated dtb from script shipped with kernel: make at91sam9263ek.dtb
And now i'm getting this error:
