A80

This is the second Allwinner SoC which uses PowerVR instead of MALI for GPU. See also SoC A31

PM => SATA Portmultiplier ??
 * Comment from Huang Benn from Cubietech on SATA on A80 at Google+ I think we will see A80 board at the market Q2 this year. Now it is just for marketing :)   BTW, A80 do support sata with PM support

=Overview=

Currently, there is no linux-sunxi support available. We only just got our hands on an SDK, and devices are slowly becoming available.

Original SDK

 * SDK (tarball)
 * SDK (unpacked)

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

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. So far we do not have the source.

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.

Cubietech Kernel
The cubietech guys made a kernel available for a while, but then Allwinner told them to take it down again. So much for playing nice.

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.
