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/hikey/96Boards-Hikey-Rev-A1.pdf

A SoC datasheet can be found here: -
https://github.com/96boards/documentation/blob/master/hikey/
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

  > mkdir -p ~/hikey/src ~/hikey/bin
  > cd ~/hikey/src
  > git clone https://github.com/96boards/edk2.git
  > git clone https://github.com/96boards/arm-trusted-firmware.git
  > git clone https://github.com/96boards/l-loader.git
  > git clone https://github.com/96boards/burn-boot.git

Get the BL30 mcuimage.bin binary. It is shipped as part of the UEFI source.
The latest version can be obtained from the edk2 repo.

  > cp edk2/HisiPkg/HiKeyPkg/NonFree/mcuimage.bin ~/hikey/bin/

Get nvme.img binary (check this link is still the latest)
  > wget -P ~/hikey/bin https://builds.96boards.org/releases/reference-platform/debian/hikey/16.03/bootloader/nvme.img

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

  > 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)
==================================

  > cd ~/hikey/src/atf
  > make CROSS_COMPILE=aarch64-linux-gnu- all fip \
    BL30=~/hikey/bin/mcuimage.bin \
    BL33=~/hikey/bin/u-boot.bin DEBUG=1 PLAT=hikey

Copy resulting binaries
  > cp build/hikey/debug/bl1.bin ~/hikey/bin
  > cp build/hikey/debug/fip.bin ~/hikey/bin

Compile l-loader
===============
  > cd ~/hikey/l-loader
  > make BL1=~/hikey/bin/bl1.bin all
  > cp *.img ~/hikey/bin
  > cp l-loader.bin ~/hikey.bin

These instructions are adapted from

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.

The command below assumes HiKey enumerated as the first USB serial port
  > sudo ~/hikey/burn_boot/hisi-idt.py -d /dev/ttyUSB0 --img1=~/hikey/bin/l-loader.bin

2. Once LED 0 comes on solid, HiKey board should be detected as a fastboot device by plugging a USB A to mini B
   cable from your PC to the USB OTG port of HiKey (on some boards I've found this to be unreliable).

  > sudo fastboot devices

0123456789ABCDEF	fastboot

3. Flash the images

  > sudo fastboot flash ptable ~/hikey/bin/ptable.img
  > 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. On 'new' boards I've had to do the
   flashing twice in the past to avoid an ATF error.

   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.

See working boot trace below (by default trace is now output to UART3 not UART0 on latest
ATF, U-Boot and Kernel sources): -

debug EMMC boot: send RST_N .
debug EMMC boot: start eMMC boot......
load fastboot1!

Switch to aarch64 mode. CPU0 executes at 0xf9801000!
