LinkSprite pcDuino Lite WiFi

= Identification =

A white PCB with an A10 chip and Arduino compatible headers on it. Sticker on the back of the board helpfully reads "pcDuino lite WiFi".

= Sunxi support =

Current status

 * Supported by the upstream U-Boot and kernel
 * Supported by legacy sunxi/legacy kernel v3.4
 * Not supported by the legacy U-Boot, though basic implementation is available in 3rd party work-in-progress github branch.

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

Sunxi/Legacy U-Boot
This board is not supported by legacy U-Boot. Use pcDuino_Lite_WiFi_config from 3rd party development branch.

Mainline U-Boot
Config Linksprite_pcDuino_defconfig for LinkSprite_pcDuino works fine for pcDuino-Lite-WiFi board as well.

Sunxi/Legacy Kernel
Use the pcduino-lite-wifi.fex file.

Mainline kernel
Use sunxi_defconfig kernel configuration file adding extra device drivers if needed. For instance, make sure to enable CONFIG_RTL8192CU in order to make WiFi card work. Device-tree sun4i-a10-pcduino.dts for LinkSprite_pcDuino works fine for pcDuino-Lite-WiFi board as well. Though it may need to be tweaked depending on the Arduino shield in use.

Building images using Yocto
Core images for pcDuino-Lite-WiFi board can be built using the following basic building blocks:


 * poky: reference distribution of the Yocto Project
 * meta-openembedded: collection of layers for the OE-core universe
 * meta-sunxi: official sunxi OpenEmbedded layer for Allwinner-based boards

This README provides build instructions specific to pcDuino-Lite-WiFi board including the following configurations:
 * images with sunxi/legacy U-Boot and kernel based on Yocto v1.8 Fido release
 * images with upstream U-Boot and kernel based on Yocto v2.1 Krogoth release

Building images using Buildroot
Support for pcDuino boards has been added to buildroot. Build instructions are available in readme.txt. Follow the same instructions for pcDuino-Lite-WiFi.

= Adding a serial port =



P3 header with 3 pins (TX - pin with square pad in the corner, GND, RX) exposes UART0. Make sure to refer to UART howto.
