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 panda board
|
|
---------------------------
|
|
|
|
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.
