Wiki

These pages have been put together by scraping information from the SDK.

Software

Original SDK

The SDK contains customized sources for U-boot, Linux, Android and buildroot.

SDK Content

  • Linux Kernel: A80/lichee/linux-3.4
  • Buildroot: A80/lichee/buildroot
  • U-boot: A80/lichee/brandy/u-boot-2011.09
  • Various Allwinner tools: A80/lichee/tools


Building images with the SDK

On Debian-like systems the following 32bit packages are required:

  • lib32stdc++6
  • lib32z1

To build the image: 

wget http://dl.linux-sunxi.org/SDK/A80/A80_SDK_20140728_lichee.tar.gz
tar -xzf A80_SDK_20140728_lichee.tar.gz
cd lichee/
./build.sh config
./build
./build pack

Boot0

Boot0 initializes the DRAM, basic clocks and loads U-boot from NAND or MMC. There is no boot1 on A80. Boot0 directly loads U-boot.

The sources can be found under https://github.com/allwinner-zh/bootloader/tree/master/basic_loader/boot0

Unfortunately you need the ARMCC (proprietary ARM C compiler) to compile the source code.

Binaries of boot0 can be found in the SDK under lichee/tools/pack/chips/sun9iw1p1/bin/

Android

Preliminary link to a Cubitech download for A80 kernel including a Android sun9i image OptimusBoard Boot Log (Android)

fastboot (under windows)

The optimus/pcduino8 board has the fastboot feature in its bootloader. Once booted into it, the device will identify itself as: 

VID:1F3A PID:1010

Under windows, no driver can be found, but it is however possible to force the installation of the fastboot driver.

To make fastboot work from a PC, we need to change the fastboot code because Google hard-coded its partners into the fastboot source code. To be able to use fastboot we need to add 0x1F3A as Allwinner and compile this. A prebuilt windows binary is available here.

GPL violations

As is usual, there are the libnand and libisp violations. But with A80, Allwinner decided to step this up a notch, or two, or all the way to 11.
