Sunxi support

Current status

Give a brief overview of the current status of support under sunxi here.

Images

Optional. Add MANUFACTURER DEVICE specific sunxi ROM images here. E.g. a livesuit image or some other linux image which uses linux-sunxi code. Do not put non-sunxi images here, they should live under See also. If no sunxi based images are available, this section can be removed.

HW-Pack

Optional. Add MANUFACTURER DEVICE sunxi HW-pack specifics here. When empty, this section can be removed.

BSP

Optional. Add MANUFACTURER DEVICE sunxi BSP specifics here. When empty, this section can be removed.

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

Use the MANUFACTURER_DEVICE build target.

Mainline U-Boot

Use the Nintendo_NES_Classic_Edition_defconfig build target.

Linux Kernel

BSP Kernel

Use the nintendo_nes_classic_clv001.fex file.

Mainline kernel

Use the 'sun8i-r16-nintendo-nes-classic.dtb' device-tree binary.

Use the 'sun8i-r16-nintendo-super-nes-classic.dtb' device-tree binary.

Tips, Tricks, Caveats

Add MANUFACTURER DEVICE specific tips, tricks, Caveats and nice to have changes here.

FEL mode

The RESET button triggers FEL mode. Alternatively, send the character '2' to UART (DRAM is NOT initialized), or run 'fastboot' command on stock U-Boot (DRAM is initialized).

To verify you have successfully entered FEL mode, check the output of sunxi-fel version. For the Nintendo NES Classic Edition, it should look like:

AWUSBFEX soc=00001667(A33) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000

Stock U-Boot

To enable boot0 debug mode (it gives command prompt on U-Boot), send the character 's' to UART.

HDMI

EPMI EP952 bridge chip is used.

Gamepad

compatible with Wii Classic Controller. (i.e. I2C)

PG3/PG2 are used to detect controllers. (HIGH: connected)

PF0-PF5 (SDC0)

SDC0 pads on SIDE-B

There are PF0-PF5 and DCDC1 on SIDE-B. They can be used for SDC0.

Device specific topic

If there are no further device specific topics to add, remove these sections.

...

Adding a serial port (voids warranty)

This section explains how to attach a serial port to the device. Make sure it refers to our UART howto. For a development board, you can just mention how to find the header with the pins and include a picture, and you can remove the warranty voiding warning.

Device disassembly

If necessary, provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped. If pins do need to be popped, mention the Plastic tool howto.

Locating the UART

UART pads on SIDE-A

Describe how to find the RX,TX,GND signals here, and mention the UART howto.

There are PB0/PB1 (for mainline) and PF2/PF4 (for stock firmware) on SIDE-A.

If you want to use the PF2/PF4 pins using the mainline U-Boot, you'll need to change CONS_INDEX to 1, and set UART0_PORT_F in menuconfig.

Pictures

Take some pictures of your device, upload them, and add them here. DO NOT UPLOAD PICTURES WHICH YOU PLUCKED OFF THE INTERNET.

Nintendo GPL Violations

Nintendo uses the A33/R16 in its products. Nintendo provides a source code zipfile on their website, in an attempt to comply with open source licenses, but Nintendo ends up distributing the same binaries that Allwinner has been distributing with it's supposed source code releases before.
