Texas Instruments AM335x
|
|
========================
|
|
|
|
The Texas Instruments AM335x SoCs have a two-stage boot process. The first stage
|
|
loader, also known as MLO is loaded by the ROM code. The MLO loads the second stage
|
|
loader from the same medium.
|
|
|
|
Building barebox
|
|
----------------
|
|
|
|
The TI AM335x boards in barebox are covered by the ``am335x_mlo_defconfig``
|
|
for the MLO and ``am335x_defconfig`` for the regular barebox image. The
|
|
resulting images will be placed under ``images/``:

Some boards come in different variants, make sure to pick the correct one.

|
Starting and updating barebox
|
|
-----------------------------
|
|
|
|
SPI NOR and NAND
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
The regular board images can be started from another bootloader, see
|
|
:ref:`second_stage`. The board should provide update handlers
|
|
to update (or initially install) barebox on SPI NOR or NAND, see :ref:`update`.
|
|
|
|
SD/MMC
|
|
^^^^^^
|
|
|
|
To start barebox from SD/MMC prepare a card with a FAT filesystem. Copy the MLO
|
|
file for your board to the card and name it ``MLO``. Copy the regular image
|
|
for your board to the card and name it ``barebox.bin``.
