Closed source binaries

The following components requires a closed source binary for better hardware support:

• TI wlan firmware (wl18xx)
  • Git: http://git.ti.com/wilink8-wlan/wl18xx_fw
  • Branch: R8.5
• Extra firmware files available from firmware-linux
• Mali (requires EULA)

Downloading the pre-built binaries

The build is composed by the traditional Android image files (boot, cache, system and userdata), but to avoid incompatibilities issues with older bootloaders, or different partition tables, it’s also recommended to flash the bootloader.

Bootloader files:

wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/bootloader/l-loader.bin
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/bootloader/nvme.img
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/bootloader/fip.bin
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/bootloader/ptable-aosp-4g.img
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/bootloader/ptable-aosp-8g.img
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/bootloader/hisi-idt.py

CE AOSP RPB image:

wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/boot_fat.uefi.img.tar.xz
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/cache.img.tar.xz
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/userdata.img.tar.xz
wget http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/userdata-8gb.img.tar.xz

Since system.img requires the user to accept an End User License Agreement covering the rights to download and use the proprietary Mali userspace driver, it needs to be manually downloaded via browser. Please go to http://builds.96boards.org/releases/reference-platform/aosp/hikey/15.12/system.img.tar.xz and follow the instructions to download the file.

Uncompress the .tar.xz files using your operating system file manager, or with the following command, for each file:

xz --decompress [filename].tar.xz; tar -xvf [filename].tar

Flashing

Bootloader

To flash the bootloader the recovery mode is required. For more information about the recovery mode, how to enable and use, please go to https://github.com/96boards/documentation/wiki/Reference-Bootloader-Hikey#enabling-recovery-mode

Now you need to identify if your device contains 4G or 8G of eMMC (LeMaker produces 2 HiKey versions, one with 4G and another with 8G of storage). The ptable-aosp and userdata files will differ depending on the board you have.

On recovery mode, flash the bootloader with the following command:

sudo python hisi-idt.py --img1=l-loader.bin -d /dev/ttyUSB0

Then on a 4G compatible device:

sudo fastboot flash ptable ptable-aosp-4g.img

Or the following on a 8G compatible device:

sudo fastboot flash ptable ptable-aosp-8g.img

Then flash UEFI:

sudo fastboot flash fastboot fip.bin

Change ttyUSB0 to the right interface name that gets exported to your host system.

Make sure to reboot the board after updating the partition table (ptable-aosp), otherwise flashing the system image might fail.

Boot, System, Cache and Userdata

Fastboot is required to flash boot, system, cache and userdata.

Flashing boot, cache, system and userdata:

Enable fastboot (either via recovery or by changing the boot jumpers), and then just flash the required files:

sudo fastboot flash boot boot_fat.uefi.img
sudo fastboot flash cache cache.img
sudo fastboot flash system system.img

Then on a 4G compatible device:

sudo fastboot flash userdata userdata.img

Or the following on a 8G compatible device:

sudo fastboot flash userdata userdata-8gb.img

Once flashed, make sure recovery mode is not enabled (pin3-pin4 on J15), then just reboot the board and enjoy :-)
