Linux Kernel
Expansion ports
The Cubie A5E has a 40-pin, 0.1" populated connector with several low-speed interfaces.
The primary function follows loosely the Raspberry Pi pin assignment, but pinmuxing gives access to more interfaces (not all at the same time).

Tips, Tricks, Caveats
FEL mode
A dedicated FEL button. FEL mode will be entered without an SD card and with no valid eGON signature on the SPI flash. Alternatively the usual FEL trigger SD card image can be used.
The USB-C connector used to power the board carries the USB-OTG signals for the FEL mode, so the board needs to be powered through a host computer or a powered USB hub for using FEL mode.
LEDs
There are two unlabelled LEDs on the board, a blue and a green one. According to the schematic they are Power (green) and Status (blue), but both are connected to GPIOs (PC12 and PC13), so need active software toggling to light up.
SPI booting
The board contains a 16MB SPI NOR flash chip, and the SoC can boot firmware from there.
Serial port
The UART pins are located at PIN 8 and PIN 10 at 40P GPIO of the board. Just attach some leads according to our UART Howto.
