The board helpfully reads "A20-OLINUXINO-MICRO".
- 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.
- The .fex file can be found in sunxi-boards as a20-olinuxino_micro.fex
Everything else is the same as the manual build howto.
Use the sun7i-a20-olinuxino-micro.dts device-tree file for the 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.
