IMX6UL kernel panic when booting(Arch Linux)

[iecheniq]

I have an Argon i.MX 6UL board. I flashed the fsl-image-gui-imx6ulnxpuiopb.sdcard that comes with it into an SD Card. When I boot the board from the SD Card I get a Kernel Panic. I get the following error from the console log:

Unhandled fault: external abort on non-linefetch (0x1008) at 0xa0a40fa8
pgd = 80004000

Internal error: : 1008 [#1] PREEMPT SMP ARM

The OS is Arch Linux.

Please help me find the solution to this. Thanks in advance

Here is the complete console log:

Hi Igor,

Thanks for the reply. I already tried to boot the board using the documentation with no luck. Unfortunately the documentation is out of date.
