6. HiKey

HiKey is one of 96boards. Hisilicon Kirin6220 processor is installed on HiKey.

More information are listed in link.

6.1.2. Build Procedure

  • Fetch all the above repositories into local host. Make all the repositories in the same ${BUILD_PATH}.

git clone https://github.com/ARM-software/arm-trusted-firmware -b integration
git clone https://github.com/OP-TEE/optee_os
git clone https://github.com/96boards-hikey/edk2 -b testing/hikey960_v2.5
git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
git clone https://git.linaro.org/uefi/uefi-tools
git clone https://github.com/96boards-hikey/atf-fastboot

  • Create the symbol link to OpenPlatformPkg in edk2.

    $cd ${BUILD_PATH}/edk2
$ln -sf ../OpenPlatformPkg

  • Prepare AARCH64 && AARCH32 toolchain. Prepare python.

  • If your hikey hardware is built by CircuitCo, update uefi-tools/platform.config first. (optional) Uncomment the below sentence. Otherwise, UEFI can’t output messages on serial console on hikey.

    BUILDFLAGS=-DSERIAL_BASE=0xF8015000

    If your hikey hardware is built by LeMaker, nothing to do.

  • Build it as debug mode. Create your own build script file or you could refer to build_uefi.sh in l-loader git repository.

    BUILD_OPTION=DEBUG
export AARCH64_TOOLCHAIN=GCC5
export UEFI_TOOLS_DIR=${BUILD_PATH}/uefi-tools
export EDK2_DIR=${BUILD_PATH}/edk2
EDK2_OUTPUT_DIR=${EDK2_DIR}/Build/HiKey/${BUILD_OPTION}_${AARCH64_TOOLCHAIN}
# Build fastboot for Trusted Firmware-A. It's used for recovery mode.
cd ${BUILD_PATH}/atf-fastboot
CROSS_COMPILE=aarch64-linux-gnu- make PLAT=hikey DEBUG=1
# Convert DEBUG/RELEASE to debug/release
FASTBOOT_BUILD_OPTION=$(echo ${BUILD_OPTION} | tr '[A-Z]' '[a-z]')
cd ${EDK2_DIR}
# Build UEFI & Trusted Firmware-A
${UEFI_TOOLS_DIR}/uefi-build.sh -b ${BUILD_OPTION} -a ../arm-trusted-firmware -s ../optee_os hikey

  • Generate l-loader.bin and partition table for aosp. The eMMC capacity is either 8GB or 4GB. Just change “aosp-8g” to “linux-8g” for debian.

    cd ${BUILD_PATH}/l-loader
ln -sf ${EDK2_OUTPUT_DIR}/FV/bl1.bin
ln -sf ${EDK2_OUTPUT_DIR}/FV/bl2.bin
ln -sf ${BUILD_PATH}/atf-fastboot/build/hikey/${FASTBOOT_BUILD_OPTION}/bl1.bin fastboot.bin
make hikey PTABLE_LST=aosp-8g

6.2. Setup Console

  • Install ser2net. Use telnet as the console since UEFI fails to display Boot Manager GUI in minicom. If you don’t need Boot Manager GUI, just ignore this section.

    $sudo apt-get install ser2net

  • Configure ser2net.

    $sudo vi /etc/ser2net.conf

    Append one line for serial-over-USB in below. #ser2net.conf

    2004:telnet:0:/dev/ttyUSB0:115200 8DATABITS NONE 1STOPBIT banner

  • Start ser2net

    $sudo killall ser2net
$sudo ser2net -u

  • Open the console.

    $telnet localhost 2004

    And you could open the console remotely, too.

6.3. Flash images in recovery mode

  • Make sure Pin3-Pin4 on J15 are connected for recovery mode. Then power on HiKey.

  • Remove the modemmanager package. This package may cause the idt tool failure.

    $sudo apt-get purge modemmanager

  • Run the command to download recovery.bin into HiKey.

    $sudo python hisi-idt.py -d /dev/ttyUSB1 --img1 recovery.bin

  • Update images. All aosp or debian images could be fetched from link.

    $sudo fastboot flash ptable prm_ptable.img
$sudo fastboot flash loader l-loader.bin
$sudo fastboot flash fastboot fip.bin
$sudo fastboot flash boot boot.img
$sudo fastboot flash cache cache.img
$sudo fastboot flash system system.img
$sudo  fastboot flash userdata userdata.img

6.4. Boot UEFI in normal mode

  • Make sure Pin3-Pin4 on J15 are open for normal boot mode. Then power on HiKey.
