1.2 Getting started

1.2.1 Prerequisites

Before you power up your HiKey970 board for the first time you will need the following:

 HiKey970 board.

 A 96Boards compliant power supply.

 A HDMI LCD Monitor that supports a resolution of 1080P/60Hz.

 HDMI-HDMI cable cable to connect the board to the Monitor.

 A computer keyboard with USB interface

 A computer mouse with USB interface.

1.2.2 Starting the board for the first time

To start the board, follow these simple steps:

Step 1. Connect the HDMI cable to the HiKey970 HDMI connector (marked J2001) and to

the LCD Monitor.

Step 2. Connect the keyboard to the boards USB connector marked J1901(or J1902) and the

mouse to the USB connector marked J1902(or J1901).

Step 3. Ensure that the boot switches SW2402 are set to ‘1000’, on/off/off/off position.

Step 4. Connect the power supply to power connector J401.

Once you plug the power supply into a power outlet the board will start the booting process,

and you should see Android boot up.

Please note that the first boot takes several minutes due to Androids initialization. Subsequent

boot times should be faster.

1.3 HiKey970 Overview

1.3.1 Boot switches and UART debug

The HiKey board has multiple boot options that are user selectable in hardware which can be

set via Switch SW2402.

 Auto Power Switch

ON: system will boot up automatically when the power supply is applied.

OFF : Pressing the power switch is required to boot up the system.

 Boot Setting Switch

ON: the will attempt to program the UFS flash from USB OTG source. This should ONLY be

used if the first stage bootloader is corrupted or needs to be replaced.

OFF : the unit boots from the first stage bootloader installed in the onboard UFS device.

 User Jumper

Connected to GPIO_055 on the SoC and UEFI mode

ON : GPIO_055 will be pulled low, the board will boot up UEFI mode

OFF: GPIO_055 will be pulled High, the board will boot up the system

 I2S SEL

ON: I2S0 will connect Low Speed Expansion Connector

OFF: I2S0 will connect other channel.

The HiKey board also has an option for a Debug UART Type C J3101. This is normally used

by the first stage bootloader developers, and is connected to the UART6 port of the SoC.

1.3.2 POWER on button /reset button

The power button S2403 can be used to power up, power down the system.

 A simple press and release powers ON the board provided the Auto Power Jumper is not

installed.

 A press and release will then power OFF the board

The Reset button S2402 can be used to reset the system.

Figure 1-4 Powr/Reset

It is also possible to connect external switches for power on/off . This is implemented by

routing the specific power signals to the low speed bus connector J2101.4(PWRON_N) and

J2401.6(EXP_RSTOUT_N).

1.3.3 DC in jack

DC Power is provided via the DC jack at P401. This is a CUI PJ-041H connector with a

center pin diameter of 1.65mm configured with positive polarity (center +). An 8V up to 18V

power supply at a minimum of 2A rating can be used to provide sufficient board power for on

system requirements as well as external devices. Additional current rating may be required for

mezzanine boards or modules. DC Power can also be supplied via the SYS_DCIN pins on the

low speed expansion J2101.

NOTE: Power should not be supplied simultaneously from multiple sources

1.3.4 Low speed expansion connector

The HiKey board features two expansion connectors: one low speed expansion connector and

one high speed. The low speed expansion connector carries GPIO and other low speed

interfaces. The connector is a low profile 40 pin female 2mm receptacle (20x2) of a specified

height of 4.5mm height.

The low speed expansion brings out 1.8V level SoC signals such as UART2 and UART3,

I2C0 and I2C1, GPIO signals as well as SPI, Audio, Reset, 1.8V and Ground. The complete

list of SoC signals is shown in Table 1 below:

GPIO_034_USBSW_SEL

The HiKey board utilizes a single SoC USB interface without USB protocol hardware split

transfer support. The USB interfaces are therefore subject to the following restrictions:

 The type C or the Type A/Mezzanine board interfaces may be used depending on the

state of GPIO_034_USBSW_SEL. Both interfaces may not be used at the same time.

 The type C port supports a single attached device with USB slave operations or USB

host high speed, full speed or low speed operations.

 The Type A/Mezzanine board interfaces cannot support mixed speed devices. All

attached devices must be of the same type – high speed, full speed or low speed.

Furthermore, the HiKey board must be configured in software to support either full

speed/low speed devices (default) or high/super speed devices on these ports.

1.3.9 System and user LEDs

There are four status LEDs and four User LEDs on the HiKey board. The user LEDs can be

programmed by the SoC directly.

 D3305 – WiFi LED

The WiFi activity LED is a Yellow type surface mount 0603 LED.

 D3306- LED

The activity LED is a Blue Type surface mount 0603 LED .

 D3301-D3304 – USER LEDs

The four user LEDs are surface mount Green Type 0603 LED .

 D3308-GPS LED

 D3307-CAN LED

1.3.10 JTAG header

The HiKey board includes the option for soldering a 10 pin header that brings out the SoC

signals for JTAG debug. A FTSH-105-01-F-DV header can be populated at J2501.
