== Pin definition ==
[[file:Hikey960-pin-def.jpg]]

* UART signals are driven at 1.8V.

== Build FW ==

* Download the Android source tree:
** repo init -u https://android.googlesource.com/platform/manifest -b master
** repo sync -j8

*Build:
** . ./build/envsetup.sh
** lunch hikey960-userdebug
** make -j24

== Installing initial images ==
*Select fastboot mode by turning ON switch 3 (for details, refer to the HiKey 960 Getting Started guide).
*Power the board.
*Flash initial images:
** cd device/linaro/hikey/installer/hikey960
*Turn OFF switch 3 and power cycle the board.

== Flashing images ==
*Enter fastboot mode by turning ON switch 3.
*Flash images by running the following commands:
** fastboot flash boot out/target/product/hikey960/boot.img
*Turn OFF switch 3 and power cycle the board.

== Building the kernel ==
*Run the following commands:
**mkdir repo-common
**cd repo-common
**repo init -u https://android.googlesource.com/kernel/manifest -b hikey-linaro-android-4.19
**repo sync -j8 -c
**rm -rf out
**rm build.config
**BUILD_CONFIG=hikey-linaro/build.config.hikey960 ./build/build.sh
*Update the kernel in the boot image.
**Copy hi3660-hikey960.dtb (out/android-hikey-linaro-4.19/dist/hi3660-hikey960.dtb) to the hikey-kernel directory as file hi3660-hikey960.dtb-4.19.
**Copy the Image file (out/android-hikey-linaro-4.19/dist/Image.gz-dtb) to the hikey-kernel directory as file Image.gz-dtb-hikey960-4.19.
<pre>
 cp repo-common/out/android-hikey-linaro-4.19/dist/hi3660-hikey960.dtb hikey960/device/linaro/hikey-kernel/hi3660-hikey960.dtb-4.19
 cp repo-common/out/android-hikey-linaro-4.19/dist/Image.gz-dtb hikey960/device/linaro/hikey-kernel/Image.gz-dtb-hikey960-4.19
</pre>
*Make the boot image:
**make bootimage -j24

== Setting the serial number ==
=== To set the random serial number, run ===
**fastboot getvar nve:SN@16\_DIGIT\_NUMBER
*Bootloader exports the generated serial number to the kernel using androidboot.serialno=.

=== Setting monitor resolution ===
*Edit the device/linaro/hikey/hikey960/BoardConfig.mk parameter BOARD_KERNEL_CMDLINE and configure the video setting. For example, the setting for a 24-inch monitor is video=HDMI-A-1:1280x800@60.

== Android note ==
* Disable ICMP for enable ping
** sysctl -w net.ipv4.icmp_echo_ignore_all=0
