Fex Guide

Translated from Chinese

FEX Description
A FEX file defines various aspects of how the SoC works. It configures the GPIO pins and sets up DRAM, Display, etc parameters.

Each line consists of a key = value pair combination under a [sectionheader]. All three, [sectionheader], key and value are case-sensitive. For comments a semi-colon (;) is used and everything following a semi-colon is ignored. The chip does not parse a textual version of a fex file, it gets cleaned and compiled by a fex-compiler. A reverse engineerd open source version exists in the [sunxi-tools]. Also a de-compiler which takes a binary script.bin and creates a textual script.fex. Usually, script.bin can be found on the nanda boot partition on A10 devices.

Port Definitions
Description of the GPIO configuration in the form:


 * port: 

where:


 *   is the port to configure (ie. PH15)


 *   is the function to configure the port for, mux 0 is as input, mux 1 as output and for 2-7 see A10/PIO for details.


 *  is 0 = disabled; 1 = pullup enabled; 2 = pulldown enabled (only valid when port is an input)


 *   defines the output drive in mA, values are 0-3 corresponding to 10mA, 20mA, 30mA and 40mA.


 *   sets the initial output level for the port; 0 = low; 1 = high (only valid for outputs)

The  and can be set to which means don't change. Any trailing options can be omitted.

[product]
Product version and description. It seems all fex files at this moment are at version 1.0 and use the default evaluation board name. It doesn't appear to be used internally, but requires further investigation.

 [product] version = "1.0" machine = "A10-EVB-V1.2"
 * version: string indicating fex file version.
 * machine: string indicating the board name. "A10-EVB-V1.2" appears to be a common one, seemingly to refer to the A10 Evaluation board v1.2.
