The board helpfully reads "A20-OLINUXINO-MICRO".
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
- The .fex file can be found in sunxi-boards as a20-olinuxino_micro.fex
- There are also several fex files dealing with the different LCDs in the same directory.
- For building U-boot, use the A20-OLinuXino_MICRO_defconfig target.
- There is another U-boot target for the eMMC version, A20-OLinuXino_MICRO-eMMC_defconfig.
Use the sun7i-a20-olinuxino-micro.dtb device-tree binary. See mainline kernel.
Tips, Tricks, Caveats
The recovery button triggers FEL mode.
See the Olimex LCD Modules page for more information on how to attach and set up Olimex LCD panels on this hardware.
This board has multiple expansion ports:
- GPIO-1 / LCD_CON - compatible with 4.3", 7.0", 10.1" LCD modules from Olimex, can also be used for general GPIO support.
- GPIO-2, GPIO-3, GPIO-4 - general GPIO support
- UEXT1 and UEXT2
Adding a serial port
There is a clearly marked UART on the top of the device. All you have to do is connect some wires according to our UART howto.
Also known as
There are of course no rebadgers for this device, but you might sometimes see it referred to as the A20-Olinuxino.
