+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 to enter 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):
+
+owl> ums 0 mmc 1
+
+Above command would mount debian image partition on host machine.
+
+Getting Cubieboard7 u-boot proper image:
+
+From u-boot root directory run following:
+
+#make clean
+#export CROSS_COMPILE=aarch64-linux-gnu-
+#make ARCH=arm cubieboard7_defconfig
+#make -j16
+#mkimage -A arm -T firmware -C none -O u-boot -a 0x11000000 -e 0 -d u-boot-dtb.bin u-boot-dtb.img  >/dev/null
+
+u-boot-dtb.img can now be flashed to debian image partition mounted on host machine.
+
+#sudo dd if=u-boot-dtb.img of=/dev/sdb bs=1024 seek=3072
