ODROID-C4

ODROID-C4

Board Description

Pin definition

• 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.

 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

Enable UART

• In repo-common/hikey-linaro

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
