10 This document describes build and flash steps for Actions S700 SoC based Cubieboard7
13 Cubieboard7 initial configuration
14 ---------------------------------
16 Default Cubieboard7 comes with pre-installed Android where U-Boot is configured with
17 a bootdelay of 0, entering a prompt by pressing keys does not seem to work.
19 Though, one can enter ADFU mode and flash debian image(from host machine) where
20 getting into u-boot prompt is easy.
25 Before write the firmware, let the development board entering the ADFU mode: insert
26 one end of the USB cable to the PC, press and hold the ADFU button, and then connect
27 the other end of the USB cable to the Mini USB port of the development board, release
28 the ADFU button, after connecting it will enter the ADFU mode.
30 Check whether entered ADFU Mode
31 --------------------------------
33 The user needs to run the following command on the PC side to check if the ADFU
34 device is detected. ID realted to "Actions Semiconductor Co., Ltd" means that
35 the PC side has been correctly detected ADFU device, the development board
36 also enter into the ADFU mode.

85 Firmware upgrade successfully!
87 Debian image can be downloaded from here[1].
89 Once debian image is flashed, one can get into u-boot prompt by pressing any key and from
90 there run ums command(make sure, usb cable is connected between host and target):
96 Above command would mount debian image partition on host machine.
98 Building U-BOOT proper image
99 ----------------------------
104 $ export CROSS_COMPILE=aarch64-linux-gnu-
105 $ make cubieboard7_defconfig
106 $ make u-boot-dtb.img -j16
108 u-boot-dtb.img can now be flashed to debian image partition mounted on host machine.
112 $ sudo dd if=u-boot-dtb.img of=/dev/sdb bs=1024 seek=3072
