HiKey board
###########

Introduction
============

HiKey is the first certified 96Boards Consumer Edition board. The board/SoC has:

* HiSilicon Kirin 6220 eight-core ARM Cortex-A53 64-bit SoC running at 1.2GHz.
* ARM Mali 450-MP4 GPU
* 1GB 800MHz LPDDR3 DRAM
* 4GB eMMC Flash Storage
* microSD
* 802.11a/b/g/n WiFi, Bluetooth

The HiKey schematic can be found here:
https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/HiKey_schematics_LeMaker_version_Rev_A1.pdf

The SoC datasheet can be found here:
https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/hardware-docs/Hi6220V100_Multi-Mode_Application_Processor_Function_Description.pdf

Currently the u-boot port supports:

* USB
* eMMC
* SD card
* GPIO

The HiKey U-Boot port has been tested with l-loader, booting ATF, which then
boots U-Boot as the bl33.bin executable.

Compile from source
===================

First get all the sources

.. code-block:: bash

  mkdir -p ~/hikey/src ~/hikey/bin
  cd ~/hikey/src
  git clone https://github.com/96boards-hikey/edk2 -b testing/hikey960_v2.5
  git clone https://github.com/ARM-software/arm-trusted-firmware
  git clone https://github.com/96boards-hikey/l-loader -b testing/hikey960_v1.2
  git clone https://github.com/96boards-hikey/OpenPlatformPkg -b testing/hikey960_v1.3.4
  git clone https://github.com/96boards-hikey/atf-fastboot
  wget https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/release/hisi-idt.py

Get the BL30 mcuimage.bin binary. It is shipped as part of the UEFI source.
The latest version can be obtained from the OpenPlatformPkg repo.

.. code-block:: bash

  cp OpenPlatformPkg/Platforms/Hisilicon/HiKey/Binary/mcuimage.bin ~/hikey/bin/

Get nvme.img binary

.. code-block:: bash

  wget -P ~/hikey/bin https://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/release/nvme.img

Compile U-Boot
==============

.. code-block:: bash

  cd ~/hikey/src/u-boot
  make CROSS_COMPILE=aarch64-linux-gnu- hikey_config
  make CROSS_COMPILE=aarch64-linux-gnu-
  cp u-boot.bin ~/hikey/bin

Compile ARM Trusted Firmware (ATF)
==================================

.. code-block:: bash

  cd ~/hikey/src/arm-trusted-firmware
  make CROSS_COMPILE=aarch64-linux-gnu- all fip \
    SCP_BL2=~/hikey/bin/mcuimage.bin \
    BL33=~/hikey/bin/u-boot.bin DEBUG=1 PLAT=hikey

Copy the resulting FIP binary

.. code-block:: bash

  cp build/hikey/debug/fip.bin ~/hikey/bin

Compile ATF Fastboot
====================

.. code-block:: bash

  cd ~/hikey/src/atf-fastboot
  make CROSS_COMPILE=aarch64-linux-gnu- PLAT=hikey DEBUG=1

Compile l-loader
================

.. code-block:: bash

  cd ~/hikey/src/l-loader
  ln -sf ~/hikey/src/arm-trusted-firmware/build/hikey/debug/bl1.bin
  ln -sf ~/hikey/src/arm-trusted-firmware/build/hikey/debug/bl2.bin
  ln -sf ~/hikey/src/atf-fastboot/build/hikey/debug/bl1.bin fastboot.bin
  make hikey PTABLE_LST=aosp-8g

Copy the resulting binaries

.. code-block:: bash

  cp *.img ~/hikey/bin
  cp l-loader.bin ~/hikey/bin
  cp recovery.bin ~/hikey/bin

These instructions are adapted from
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/plat/hikey.rst

Flashing
========

1. Connect the second jumper on J15 BOOT SEL, to go into recovery mode and flash l-loader.bin with
the hisi-idt.py utility. Then connect a USB A to B mini cable from your PC to the USB OTG port of HiKey and execute the below command.

The command below assumes HiKey enumerated as the first USB serial port

.. code-block:: bash

  sudo python ~/hikey/src/hisi-idt.py -d /dev/ttyUSB0 --img1 ~/hikey/bin/recovery.bin

2. Once LED 0 comes on solid, HiKey board should be detected as a fastboot device.

.. code-block::

  sudo fastboot devices

  0123456789ABCDEF	fastboot

3. Flash the images

.. code-block::

  sudo fastboot flash ptable ~/hikey/bin/prm_ptable.img
  sudo fastboot flash loader ~/hikey/bin/l-loader.bin
  sudo fastboot flash fastboot ~/hikey/bin/fip.bin
  sudo fastboot flash nvme ~/hikey/bin/nvme.img

4. Disconnect second jumper on J15 BOOT SEL, and reset the board and you will now (hopefully)
   have ATF, booting u-boot from eMMC.

   Note: To get USB host working, also disconnect the USB OTG cable used for flashing. Otherwise you
   will get 'dwc_otg_core_host_init: Timeout!' errors.
