HiKey
=====

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

More information are listed in `link`_.

How to build

-  OP-TEE
   `link <https://github.com/OP-TEE/optee_os>`__

Build Procedure
~~~~~~~~~~~~~~~

-  Fetch all the above repositories into local host.
   Make all the repositories in the same ${BUILD\_PATH}.

  .. code:: shell

       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://github.com/96boards-hikey/atf-fastboot

-  Create the symbol link to OpenPlatformPkg in edk2.

   .. code:: shell

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

-  Prepare AARCH64 && AARCH32 toolchain. Prepare python.

-  If your hikey hardware is built by CircuitCo, update *OpenPlatformPkg/Platforms/Hisilicon/HiKey/HiKey.dsc* first. *(optional)*
   console on hikey.**

   .. code:: shell

       DEFINE SERIAL_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.

   .. code:: shell

       cd {BUILD_PATH}/arm-trusted-firmware
       sh ../l-loader/build_uefi.sh 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.

   .. code:: shell

       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

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.**

   .. code:: shell

       $sudo apt-get install ser2net

-  Configure ser2net.

   .. code:: shell

       $sudo vi /etc/ser2net.conf

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

   .. code:: shell

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

-  Start ser2net

   .. code:: shell

       $sudo killall ser2net
       $sudo ser2net -u

-  Open the console.

   .. code:: shell

       $telnet localhost 2004

   And you could open the console remotely, too.

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.

   .. code:: shell

       $sudo apt-get purge modemmanager

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

   .. code:: shell

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

-  Update images. All aosp or debian images could be fetched from `link <http://releases.linaro.org/96boards/>`__.

   .. code:: shell

       $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

Boot UEFI in normal mode
------------------------

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

-  Reference `link <https://github.com/96boards-hikey/tools-images-hikey960/blob/master/build-from-source/README-ATF-UEFI-build-from-source.md>`__
