Hardware

The i.MX53 Quick Start Board (aka LOCO) is a 1 GHz ARM Cortex-A8
embedded computer on a 3-inch by 3-inch board.

The loco boots from SD Card with the boot loader at the first sector of
it.

You can use Barebox on it:

http://git.pengutronix.de/?p=barebox.git;a=summary

Barebox

Barebox uses the same build (Kbuild) and configuration (Kconfig) tools
as the Linux kernel.

1) First you need to clone the tree

  1. git clone git://git.pengutronix.de/git/barebox.git

Most probably you want to use a released Barebox version, by running
‘git checkout \‘. Check which versions are available with ‘git
tag -l’ and use the latest one.

2) Then you need to configure it:

  1. make freescale_mx53_loco_defconfig

3) Compile it

  1. make

4) Now you need to generate your SD Card:

Plug the SD Card into your laptop and copy barebox.bin to it:

  1. dd if=barebox.bin of=/dev/sdb bs=512
  2. sync

5) plug the SD card into the board and boot it (press the boot button)

Now that you have flash, you will see Barebox booting and trying to
start the kernel from the SD card.

Kernel

You can use the mainline kernel, but take into account that not all IP
cores available in the MX53 are already supported there. It is also
possible to use Freescale’s kernel, which can be found here:

http://opensource.freescale.com/git?p=imx/linux-2.6-imx.git;a=summary

1) First you need to clone the tree:

a) Mainline

  1. git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

Note that, like with Barebox, if you aim for stability, you should take
a released kernel revision instead of some random version from git.

b) Freescale

  1. git clone http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git
  3. git checkout -b work imx_2.6.38_11.09.01

or

To speed up the clone, first clone the linus tree, then fetch freescale
as this

or use any already cloned kernel

  1. git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
  3. git remote add freescale http://opensource.freescale.com/pub/scm/imx/linux-2.6-imx.git
  5. git fetch freescale
  7. git checkout -b work freescale/imx_2.6.38_11.09.01

2) Then you need to configure the kernel:

  1. make imx5_defconfig

3) Compile it

  1. make

If you have a machine with more than one core, add -j
\.

4) now you need to generate your SD Card:

Plug the sd card on your laptop and copy barebox.bin on it

  1. dd if=arch/arm/boot/uImage of=/dev/sdb bs=512 seek=768
  2. sync

5) Plug the SD card into the board and boot it (press the boot button)

Now that you have flashed everything, you will see barebox booting and
trying to start the kernel from the SD card.
