[Buildroot] Kernel does not boot on I.MX28

[Mikael Åsberg]

Hi,

>ARCH=arm CROSS_COMPILE=/path/to/buildroot/output/host/usr/bin/arm-linux-
>to the build arguments.

I'm not sure where to put these, they will not have any effect in the Makefile...

You should definitely compile it on your host machine, that's the
easiest solution.

If you have properly use Kbuild for the build system of your module,
you should simply add
ARCH=arm CROSS_COMPILE=/path/to/buildroot/output/host/usr/bin/arm-linux-
to the build arguments.
