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

= 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.
