Updated Android 4.4 Beta and Ubuntu Images for pcDuino8 / A80 OptimusBoard Boards Released

pcDuino8 and A80 OptimusBoard are the only two Allwinner A80 development boards currently “somewhat” available, and albeit the PCB color is different, every else is basically identical, and pcDuino8 firmware should probably run on A80 OptimusBoard and vice versa. If you own any of these boards, you may interested in two images, one with Android 4.4 (beta), and one with Lubuntu, recently released by pcDuino / Linksprite.


Android 4.4 (beta) 2014-10-08 – sun9iw1p1_android_optimus.img to be flashed with PhoenixCard (Windows) or Livesuit (Linux)

Lubuntu 14.04? 2014-10-08 is comprised of two files:

  1. Kernel – pcduino8_kernel_livesuit_20141008.img to be flashed with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard.
  2. Rootfs – pcduino8_ubuntu_20141008.rar. First extract the rar files to the root of an SD card or USB flash drive. There should be two files: pcduino8_ubuntu_20141008.img and update.sh. Now connect the mass storage device to pcDuino3 / A80 Optimusboard, and reboot the board to flash the image to /dev/nandd automatically.
    The serial console should show something like:

    mount udisk succeed

    update.sh found, updating rootfs from udisk, please wait…

    writing pcduino8_ubuntu_20141008.img to nand flash

    it will take about 8 minutes to finish…

    During the update, one blue LEDs will blink quickly, and once the procedure is complete two LEDs should blink slowly (success) or fast (failure)

I have tried the Ubuntu image on A80 OptimusBoard, and the kernel update works fine, but the rootfs update (USB flash drive) failed to complete successfully, ending with “write ubuntu to nand failed. update failed, please retry.” after a few seconds. The reason being /dev/nandd partition is only 630 MB, and Ubuntu image is 1.7GB, so I’d have to repartition the flash, something that’s used to be done in the board files for older Linux kernels, but with Allwinner kernel is might be different… An unofficial source also told me an A80 GPU SDK would be released by the end of the month.

Thanks to miniNodes for the info.
