[Problem] SAMA5D27 Cortex-A5 cross compiler

Hello All

I am still a newbie to building using linix makefile cross compiling.

I have years of experience with Microchip but want to grow my knowledge in linux.

I have selected the SAMA5D27 that is part of the  ATSAMA5D27-WLSOM1-EK1 development board that has a Cortex-A5.

But I also want to implement FreeRTOS as later I want to try SafeRTOS.

I did look under the examples but even using eclipse I get the same error.

Below is my simple makefile for a starter:

But I keep on getting tmp/cc8qyeDo.s:1907: Error: selected processor does not support requested special purpose register -- `msr DAIFSET,#2'.

Think I just need to get pointed into the right direction with the correct cross compiler to use. And also the appropriate flags.

If listed. Please also just a brief installation help as I am still new to Linux-mint and learning.

Thank you in advance.
