When building U-Boot we select the architecture via Kconfig and not ARCH being passed in via the environment or make cmdline. While in here, add the doc file to the MAINTAINERS entry.

CUBIEBOARD7
|
|
===========
|
|
|
|
About this
|
|
----------
|
|
|
|
This document describes build and flash steps for Actions S700 SoC based Cubieboard7
|
|
board.
|
|
|
|
Cubieboard7 initial configuration
|
|
---------------------------------
|
|
|
|
Default Cubieboard7 comes with pre-installed Android where U-Boot is configured with
|
|
a bootdelay of 0, entering a prompt by pressing keys does not seem to work.
|
|
|
|
Though, one can enter ADFU mode and flash debian image(from host machine) where
|
|
getting into u-boot prompt is easy.
|
|
|
|
Enter ADFU Mode
|
|
----------------
|
|
|
|
Before write the firmware, let the development board entering the ADFU mode: insert
|
|
one end of the USB cable to the PC, press and hold the ADFU button, and then connect
|
|
the other end of the USB cable to the Mini USB port of the development board, release
|
|
the ADFU button, after connecting it will enter the ADFU mode.
|
|
|
|
Check whether entered ADFU Mode
|
|
--------------------------------
|
|
|
|
The user needs to run the following command on the PC side to check if the ADFU
|
|
device is detected. ID realted to "Actions Semiconductor Co., Ltd" means that
|
|
the PC side has been correctly detected ADFU device, the development board
|
|
also enter into the ADFU mode.

Firmware upgrade successfully!
|
|
|
|
Debian image can be downloaded from here[1].
|
|
|
|
Once debian image is flashed, one can get into u-boot prompt by pressing any key and from
|
|
there run ums command(make sure, usb cable is connected between host and target):
|
|
|
|
.. code-block:: none
|
|
|
|
owl> ums 0 mmc 1
|
|
|
|
Above command would mount debian image partition on host machine.
|
|
|
|
Building U-BOOT proper image
|
|
----------------------------
|
|
|
|
.. code-block:: none
|
|
|
|
$ make clean
|
|
$ export CROSS_COMPILE=aarch64-linux-gnu-
|
|
$ make cubieboard7_defconfig
|
|
$ make u-boot-dtb.img -j16
|
|
|
|
u-boot-dtb.img can now be flashed to debian image partition mounted on host machine.
|
|
|
|
.. code-block:: none
|
|
|
|
$ sudo dd if=u-boot-dtb.img of=/dev/sdb bs=1024 seek=3072
