I just validated an easy method for getting started with Debian
using the Wheezy image from armhf.com.

After creating an SD card from the .xz file, copy the following
from the SD card that shipped with the board (the Timesys image)
into the rootfs/ tree:

	6x_bootscript
	/boot/uImage
	/lib/modules/3.0.35-ts-armv7l/

The Timesys image is available here:
	http://boundarydevices.com/eula?file=timesys-20130401.tar.gz

It requires acknowledgement of a license agreement because of
some closed-source Freescale bits as discussed here:
	http://boundarydevices.com/license-and-registration-please/

I'll build a package with the latest versions and upload it
separately.

The boot loader, kernel and modules are of course GPL'd and freely
available:

U-Boot: branch 'production' is what ships, Debian updates are in
	'staging':
	https://github.com/boundarydevices/u-boot-imx6/tree/production

Kernel: (branch boundary-imx_3.0.35_1.1.1 is the latest)
	https://github.com/boundarydevices/linux-imx6/tree/boundary-imx_3.0.35_1.1.1

The source for the boot script is here:
	https://github.com/boundarydevices/u-boot-imx6/blob/production/board/boundary/nitrogen6x/6x_bootscript.txt

These instructions will work for either SABRE Lite or Nitrogen6x.

You're much more likely to be pleased with the process using the
3.0.35 kernel. Though it's a bit dated on the kernel end, it's much
more widely used and has much better support for peripherals.

Let us know if you have any difficulty.

Regards,


Eric
