Texas Instruments OMAP/AM335x
=============================

Texas Intruments OMAP SoCs have a two staged boot process. The first stage is
known as Xload which only loads the second stage bootloader. barebox can act as
both the first and the second stage loader. To build as a first stage loader
build the \*_xload_defconfig for your board, for second stage build the normal
\*_defconfig for your board.

Bootstrapping a PandaBoard
--------------------------

The Panda board boots from SD card. The OMAP Boot ROM code loads a file named
'MLO' on a bootable FAT partition on this card. There are several howtos and
scripts on the net which describe how to prepare such a card (it needs a
special partitioning). The same procedure can be used for barebox. With such a
card (assumed to be at /dev/sdc) the following can be used to build and install
barebox::

  # mount -t fat /dev/sdc1 /mnt
  # make panda_xload_defconfig
  # make
  # cp barebox.bin.ift /mnt/MLO
  # make panda_defconfig
  # make
  # cp barebox.bin /mnt/barebox.bin
  # umount /mnt

Bootstrapping a Beagle board is the same with the corresponding Beagle board defconfigs

Networking
----------

The Beagle board does not have ethernet, but a USB ethernet dongle can be used
for networking. the Panda board has an integrated USB ethernet converter which
exactly behaves like an external dongle. Barebox does not automatically detect
USB devices as this would have bad effects on boot time when USB is not needed.
So you have to use the [[commands:usb|usb]] command to trigger USB detection.
After this a network device should be present which can be used with the normal
[[commands:dhcp|dhcp]] and [[commands:tftp|tftp]] commands.
