Identification

On the back of the board, it helpfully reads "pcDuino Dual core".

Sunxi support

Current status

Supported.

There are even patches for mainline on the Mailing list. These provide basic board support, along with USB and SATA.

BSP

Manual build

  • For building u-boot, use the "pcduino3" target.
  • The .fex file can be found in sunxi-boards as linksprite_pcduino3.fex

Everything else is the same as the manual build howto.

Mainline kernel

Use the sun7i-a20-pcduino3.dts device-tree file for the mainline kernel.

In order to make ethernet work for pcDuino3b, you will have to edit the device-tree file: simply copy &gmac{...} section from sun7i-a20-pcduino3-nano.dts to sun7i-a20-pcduino.dts.

Tips, Tricks, Caveats

FEL mode

The UPGRADE/SW2 button triggers FEL mode.

Expansion headers

pcDuino3b headers

SPI0 pins are wired to both: P7 and J8 pins. SPI0 clock is additionally wired to LED_CLK.

Adding a serial port

UART pads

There is a 3pin 2.54mm pitch header near the wifi module, called "UART_0" (P3 - Debug Port). All you have to do is attach some jumper wires according to our UART howto.

Variants

At some point in 2015, Linksprite started selling an updated variant of the pcDuino V3 called pcDuino v3B (or pcDuino3B). Compared to the original board, v3B updated the ethernet connection to Gigabit Ethernet. Other than that, the board layout stayed the same.
