can't build imx_3.10.17_1.0.0_beta from git.freescale.com

[EdSutter]

I've recently pulled down imx_3.10.17_1.0.0_beta  from git.freescale.com to try building it and I get this error message:

arch/arm/mach-imx/lpddr2_freq_imx6.S:365: Error: selected processor does not support ARM mode `dsb'

I'm using arm-2013.05-24-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 toolset,

and starting with imx_v6_v7_defconfig.

Anyone else seeing this?

[fabio_estevam · Accepted solution]

The default config for 3.10.17 is the imx_v7_defconfig. Please try that one instead.

How does that fix the bug in the Makefile though ? ;-)

[EdSutter]

Marek,

Yea, good question...

I was going to try the patch you sent, but then when Fabio's response that was an

easier first-try.  It built clean, so I guess the different config caused the build to steer

around the snippet of code that caused my original error...

If I get some time, I'll dig deeper.

Regardless, thanks for replying.

Fabio,

I built this and I *almost* have it running on my hardware; based on some major hacks made to the device tree.

Can you tell me, is this being used much publicly yet or is this still bleeding-edge experimental for iMX6?

Try using ARMHF toolchain , that might just be it. I suspect your toolchain is ARMEL, right ?

[EdSutter]

Quite honestly, I've never heard the terms "ARMHF" and "ARMEL" till now.

Based on some googling, it appears that the primary difference is hard/soft floating point.

So 2 questions follow...

1. I'm using arm-none-linux-gnueabi-gcc (Sourcery CodeBench Lite 2013.05-24) 4.7.3,

    how do I know if this is armhf or armel?  Is there a way to tell through the commandline?

2. Since I'm working with iMX6, shouldn't I be ok to use ARMHF?

[MarekVasut]

Try something like:

$ arm-linux-gnueabi-readelf -a `arm-linux-gnueabi-gcc -print-libgcc-file-name` | grep CPU_name | sort -u

Should tell you what your libgcc architecture is

[MarekVasut]

I managed to replicate this, please try attached patch ...

[EdSutter]

Marek,

Thanks much, I'll give this a try later today.
