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.
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
- 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
