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 ARCH=arm 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
