The Olimex A13-OLinuXino-Micro is a shrunk down, cheaper version of the A13-OLinuXino. The differences against the A13-OLinuXino are that it has half the ram, a single USB Host port, only u-boot and reset buttons, no RTC, battery connector, NAND or Wifi. As with all Olimex Devices this board is Open Source Hardware.
The board handily reads "A13-OLinuXino-MICRO".
- For building u-boot, use the "A13-OLinuXino-Micro" target.
- The .fex file can be found in sunxi-boards as a13-olinuxinom.fex
Everything else is the same as the manual build howto.
Use the sun5i-a13-olinuxino-micro.dts device-tree file for the mainline kernel.
Tips, Tricks, Caveats
The U-Boot button triggers FEL mode.
Even though the A13 does not provide DACs itself, the A13-Olinuxino has a VGA connector.
This is implemented through 3 separate DAC chips (NXP LVC244A) which are connected to the LCD0 lines. This in turn means that you cannot use an LCD and a VGA monitor at the same time, but this is ok as the A13 can only drive one display at a time anyway.
Due to the bandwidth limitations of the A13 SoC, the best resolution you can hope for is 800x600.
Several expansion options are provided:
- A UEXT connector. This is meant for attaching Olimex UEXT modules.
- A 10 pin IO connector (GPIO-1).
- A 40 pin IO connector (GPIO-2).
TODO: verify that the GPIO pin-outs are a 1-1 match with the A13-OLinuXino
Adding a serial port
In the top left corner of the device, there are some pins marked UART1. The pin-out is described at the back of the board. All you have to do is connect some leads according to our UART howto.
