Sunxi support

Current status

Following the manual build guild. it can be boot with mainline u-boot and mainline kernel.

USB works fine. but the default mainline kernel config needs some additional twist to make it work.

but the wifi support on the mainline kernel is WIP.

Ethernet works fine but u-boot needs a little change if you want it during u-boot.

the wired things is that I don't know why the u-boot mii bus can't get a correct PHY_ID and Ethernet initialed fail. so I create it myself.

The HDMI turns to black screen after kernel starts. the Kernel code needs a little twists to make sun4i-drm works properly.

Manual build

You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.

U-Boot

Sunxi/Legacy U-Boot

I try the tinycore introduction. choose the Cubieboard-512MB target.

Mainline U-Boot

Use the MANUFACTURER_DEVICE build target.

Linux Kernel

Mainline kernel

Use the FAMILY-CHIP-DEVICE.dtb device-tree binary.

Tips, Tricks, Caveats

There are 4 things I changed compare the manufacture board:

I solid the serial slot.
I solid the SD card slot.
I solid an additional 2 pins near the small socket.
I resolid the LED and the remote receive component. The LED is only 1 color before on the small panel board. I change it to 2 color on main board.

FEL mode

The is a pin at the edge named "KEY". short it when power on you will get to FEL.

Device specific topic

1 There is wired the mainline u-boot can't get the Ethernet RTL8021CP 's Phy_id properly.

2 HDMI works in mainline kernel needs the source to change a little bit to make it work.
