28. Socionext Synquacer

Socionext’s Synquacer SC2A11 is a multi-core processor with 24 cores of Arm Cortex-A53. The Developerbox, of 96boards, is a platform that contains this processor. This port of the Trusted Firmware only supports this platform at the moment.

28.1.3. Build Procedure

  • Firstly, in addition to the “normal” build tools you will also need a few specialist tools. On a Debian or Ubuntu operating system try:

    sudo apt install acpica-tools device-tree-compiler uuid-dev
  • Secondly, create a new working directory and store the absolute path to this directory in an environment variable, WORKSPACE. It does not matter where this directory is created but as an example:

    export WORKSPACE=$HOME/build/developerbox-firmware
    mkdir -p $WORKSPACE
  • Run the following commands to clone the source code:

    git clone https://github.com/ARM-software/arm-trusted-firmware -b master
    git clone https://github.com/tianocore/edk2.git -b master
    git clone https://github.com/tianocore/edk2-platforms.git -b master
    git clone https://github.com/tianocore/edk2-non-osi.git -b master
  • Build ATF:

    cd $WORKSPACE/arm-trusted-firmware
    make -j`nproc` PLAT=synquacer PRELOADED_BL33_BASE=0x8200000 bl31 fiptool
    tools/fiptool/fiptool create \
          --tb-fw ./build/synquacer/release/bl31.bin \
          --soc-fw ./build/synquacer/release/bl31.bin \
          --scp-fw ./build/synquacer/release/bl31.bin \
  • Build EDK2:

    export PACKAGES_PATH=$WORKSPACE/edk2:$WORKSPACE/edk2-platforms:$WORKSPACE/edk2-non-osi
    export ACTIVE_PLATFORM="Platform/Socionext/DeveloperBox/DeveloperBox.dsc"
    export GCC5_AARCH64_PREFIX=aarch64-linux-gnu-
    unset ARCH
    . edk2/edksetup.sh
    make -C edk2/BaseTools
    build -p $ACTIVE_PLATFORM -b RELEASE -a AARCH64 -t GCC5 -n `nproc` -D DO_X86EMU=TRUE
  • The firmware image, which comprises the option ROM, ARM trusted firmware and EDK2 itself, can be found $WORKSPACE/../Build/DeveloperBox/RELEASE_GCC5/FV/. Use SYNQUACERFIRMWAREUPDATECAPSULEFMPPKCS7.Cap for UEFI capsule update and SPI_NOR_IMAGE.fd for the serial flasher.

    Note #1: -t GCC5 can be loosely translated as “enable link-time-optimization”; any version of gcc >= 5 will support this feature and may be used to build EDK2.

    Note #2: Replace -b RELEASE with -b DEBUG to build a debug.

28.1.4. Install the System Firmware

  • Providing your Developerbox is fully working and has on operating system installed then you can adopt your the newly compiled system firmware using the capsule update method:.

    sudo apt install fwupdate
    sudo fwupdate --apply {50b94ce5-8b63-4849-8af4-ea479356f0e3} \
    sudo reboot
  • Alternatively you can install SPI_NOR_IMAGE.fd using the board recovery method.
