| John Stultz | 479a7c9 | 2022-02-02 05:54:07 +0000 | [diff] [blame] | 1 | These instructions will help you in flashing the prebuilt bootloader |
| 2 | images and AOSP images (built from sources) on hikey960. |
| 3 | |
| 4 | There are two versions of HiKey960: v1 and v2. |
| 5 | * v1 is using Jumper (J2001) |
| 6 | * v2 is using DIP switch (SW2201). |
| 7 | Both are located at the bottom side of the board. |
| 8 | |
| 9 | Jumper Pin 1-2 = DIP switch 1 (AutoBoot) |
| 10 | Jumper Pin 3-4 = DIP switch 2 (Recovery Mode) |
| 11 | JUmper Pin 5-6 = DIP switch 3 (Fastboot Mode) |
| 12 | |
| 13 | * Always power off the board before changing the switches or |
| 14 | jumpers. |
| 15 | * To boot into fastboot mode set switch 1 & 3 to ON state and |
| 16 | switch 2 to OFF state. |
| 17 | * To boot into normal mode set switch 1 to ON and switch 2 & 3 to |
| 18 | OFF state. |
| 19 | |
| 20 | To flash the OS to the board, set the jumpers to fastboot mode, and |
| 21 | power on the device. Connect a USB-C cable to the OTG port and your |
| 22 | host device. |
| 23 | |
| 24 | On your host device, run the flash-all.sh script to update boot files |
| 25 | using fastboot. It assumes that you have already build hikey960 AOSP |
| 26 | images locally, or are flashing a factory image. |
| 27 | $ ./flash-all.sh |
| 28 | |
| 29 | After that completes, power the board off, and set the switches back |
| 30 | to normal mode and boot the device. |
| 31 | |
| 32 | Known Issues: |
| 33 | ------------- |
| 34 | When flashing ontop of the HiSi bootloader, you may see the following |
| 35 | failure: |
| 36 | sending 'xloader' (151 KB)... |
| 37 | OKAY [ 0.006s] |
| 38 | writing 'xloader'... |
| 39 | FAILED (remote: flash write back vrl failure) |
| 40 | |
| 41 | This is a transient error and can be ignored. |
| 42 | |
| 43 | |
| 44 | Trouble shooting: |
| 45 | ----------------- |
| 46 | If you have any trouble booting the device after running ./flash-all.sh |
| 47 | you may need to do a board recovery. This is hopefully uncommon, but |
| 48 | may be necessary in some cases (like if your board has pre-release |
| 49 | firmware on it). In this case clone the git project here: |
| 50 | https://github.com/96boards-hikey/tools-images-hikey960/ |
| 51 | |
| 52 | And follow the instructions in the README.md |
