Merrii A80 Optimus Board

The A80 Optimus Board is a official development board for the Allwinner A80 SoC, targeting both developers and consumers.

= Identification =

The board has a clearly recognizable Allwinner logo, the name "Allwinner Tech", and "OPTIMUS BOARD", all uppercase, in the lower right hand corner.

= Sunxi support =

Sunxi Kernel
Like all A80 based devices, there is no support in our sunxi kernel.

Sunxi U-Boot
Like all A80 based devices, there is no support in u-boot-sunxi.

Mainline kernel
Mainline kernel support is queued up for 3.19. Currently only UARTs are supported.

Use the sun9i-a80-optimus.dtb device-tree file for the mainline kernel.

Mainline u-boot
Like all A80 based devices, there is no support in mainline u-boot.

Manual build
Follow SDK build howto to build u-boot and the kernel from the SDK.

Mainline kernel
Initial support for the A80 based on the A80 Optimus board is being worked on.

Use the sun9i-a80-optimus.dtb device-tree file for the mainline kernel.

= Tips, Tricks, Caveats =

FEL mode
There is no FEL mode button on this board.

Instead you can enter fel mode from U-Boot. While U-Boot is starting, type CTRL+C to interrupt it. At the prompt type efex to enter fel mode.

If booting fails entirely then FEL mode can be entered by shorting pin 29-30 on the nand/emmc with a suitable metal object (tweezer or the like), by vendor official procedure.

= Expansion Ports =

The A80 Optimus board exposes a 2 mm pitch connector for GPIO, and a Camera/MIPI connector [connector details needed].

Camera/MIPI connector
= JTAG =

The board have a dedicated JTAG port with 2mm pinspacing.

= Serial console port =



The UART header is next to the Ethernet port. The board comes with a custom USB UART cable that fits direclty into the header.
