This page needs to be properly filled according to the New Device Howto and the New Device Page guide.

The "MID" formfactor was very popular in 2012. Therefor there are probably some variations with respect to the amount of NAND, camera and wifi modules.

There is some confusion, as to which device this is. The layout of the buttons and connectors seems to be compatible with the A710, but the board is crucially different.

In 2012, this board was also sold standalone, as the Gooseberry. The gooseberry forum now is abandoned and full of spam.

BSP works properly and is able to prepare bootable SD cards and LiveSuit images, as tested on gooseberry board.

Manual build

Warning: The below instructions are for the standalone gooseberry board, they might not be suited for an actual A721 tablet.

  • For building u-boot, use the "Gooseberry_A721" target.
  • The .fex file can be found in sunxi-boards as gooseberry_a721.fex

Everything else is the same as the manual build howto.

A721 UART pads

Device disassembly

Provide a short description of how to open the device. Perhaps explain how the pins can be most easily popped.

Locating the UART

On the back of the board, there are pads marked "UART0-TX" and "UART0-RX". All you have to do is solder on some wires according to our UART howto.

Also known as

There are probably tons of rebadgers, as this formfactor was very popular and got produced by several manufacturers.

Some possible suspects are:

  • Lyric F1 (LY-F1), which probably also shipped with an A710 board.
  • TomTop c1315
  • DVC z7
  • The bare board was also sold as the Gooseberry.
