Linux does not boot, unrecognized/unsupported machine ID (r1 = 0x00000000).

Hello list,
here I am (again!) ;-)

Now I have downloaded the linux 4.5-rc6 (because I would like to use etnaviv gpu driver), configured as imx_v6_v7_defconfig, added the DEBUG_LL stuff for uart3 and added in the Makefile for dts my dts (more or less like Barebox one [in attachment] ), but here is what I get (compiling the kernel with DEBUG_LL for uart3):

It looks like something were wrong with devicetree or other machine identifier stuff...

Where is the issue???

Regards,

Hi,

Looks like the device tree is not actually used. Could you boot with -v please? Also, could you try a zImage instead of a uImage? Last not least, does the problem persist on current barebox master?

Ok, I just reproduced the problem here with barebox-2016.02.0. It is fixed in master.
