Linux Host
This section show how to install a new operating system to your HiKey970 using the fastboot method on a Linux host computer.
- Step 1: Materials and Preperations
- Step 2: Dependencies
- Step 3: Flash base firmware (if needed)
- Step 4: Boot HiKey970 into fastboot mode
- Step 5: Flash Operating System
- Step 6: Reboot
Step 1: Materials and Preperations
Materials
- HiKey970
- USB Type-A (Host machine) to USB Type-C (96Boards) cable
- 96Boards compliant power supply
Preperations
| Both are located at the bottom side of the board |
|---|
| Jumper Pin 1-2 = DIP switch 1 |
| Jumper Pin 3-4 = DIP switch 2 |
| Jumper Pin 5-6 = DIP switch 3 |
- To boot into fastboot mode everytime set switch 1 & 3 to ON state and switch 2 to OFF state.
- To boot into fastboot mode at every alternate rebooot set switch 1 to ON and switch 2 & 3 to OFF state.
- To boot into recovery mode set switch 1, 2 & 3 to ON state.`
Step 2: Dependencies
Host Linux Machine
- Android SDK “Platform-Tools” for Linux can be downloaded here
- Download appropriate operating system images from “Downloads page”
Step 3: Flash base firmware (only if necessary)
Most release-level devices should not require this step to updating the base firmware, so this step mostly applies to pre-release boards, and can be skipped (head on to Step 4 of the instructions). However, if your board does not boot after being flashed, its advised to do a recovery flash to ensure lower-level firmware components are properly flashed.
Instructions on how to do a recovery flash of the base firmware can be found here.
Step 4: Boot HiKey 970 into fastboot mode
- HiKey970 must be powered off (unplugged from power, this includes both 96Boards compliant power supply and USB Type-C connections)
- Make sure microSD card slot on HiKey970 is empty
- Jumper/Dip Switch setting should be set as follows
| Name | Switch | State |
|---|---|---|
| Auto Power up | Switch 1 | closed / ON |
| Recovery | Switch 2 | open / OFF |
| Fastboot | Switch 3 | closed / ON |
- Connect USB Type-C cable AND 96Boards compliant power supply to HiKey970, ensure USB is connected to host machine
- Open “Terminal” on host machine and execute the following command
$ sudo fastboot devices
If your HiKey970 is pre-flashed with appropriate firmware, you should see your device lised as an output:
447786182000000 fastboot
At this point you should be connected to your HiKey970 with a USB Type-A to USB Type-C cable. Your HiKey970 should be booted into fastboot mode and ready to be flashed with the appropriate images.
Step 5: Flash Operating System
AOSP
Unzip the downloaded image in a directory and execute the below commands from it to flash HiKey970 with AOSP.
$ sudo fastboot flash ptable prm_ptable.img
$ sudo fastboot flash xloader sec_xloader.img
$ sudo fastboot flash fastboot l-loader.bin
$ sudo fastboot flash fip 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
Debian (Lebian) Linux
Unzip the downloaded image in a directory and execute the below commands from it to flash HiKey970 with Lebian.
$ sudo ./flash-all-binaries.sh
Step 6: Reboot
- Unplug power to HiKey970 (both 96Boards compliant power supply and USB Type-C)
- Jumper/Dip Switch setting should be set as follows
| Name | Switch | State |
|---|---|---|
| Auto Power up | Switch 1 | closed / ON |
| Recovery | Switch 2 | open / OFF |
| Fastboot | Switch 3 | open / OFF |
- Ensure HDMI connection to monitor
- Ensure keyboard and/or mouse connection
- Plug power back into HiKey970 (96Boards compliant power supply)
- Wait for board to boot up
Congratulations! You are now booting your newly installed OS directly from UFS on the HiKey970!
