Building

Prerequisites

libusb-1.0

debian/ubuntu

apt-get install libusb-1.0-0-dev

fedora

yum install libusbx-devel

pkg-config

Repository

git clone https://github.com/linux-sunxi/sunxi-tools

Building

Those programs that need to run on the host will be built when you run:

make

The programs meant for the device, are not built per default, and you need to name them explicitly.

When you are using a cross-compiling toolchain (make sure it is added to your PATH), you need to build individual programs like so:

make CROSS_COMPILE=arm-linux-gnueabihf- meminfo

Since all these tools are tiny, you can just as well build these on the target device as well.

fexc and wrappers

fexc is a small program which can convert, back and forth, from FEX to its binary representation and back. It comes with two shortcut programs which make it easier.

fexc

Usage: ./fexc [-vq] [-I <infmt>] [-O <outfmt>] [<input> [<output>]]

infmt:  fex, bin  (default:fex)
outfmt: fex, bin, uboot  (default:bin)

When no arguments are provided, it waits on stdin. Similar, when no <output> is provided, it will dump to stdout. This is great for piping, but might mess up your terminal (type reset to have your terminal reset and make sense again).

bin2fex

This is a copy of fexc which takes a script.bin and dumps the .fex text.

fex2bin

This is a copy of fex which takes the .fex text file and dumps the binary.

pio

Manipulatee PIO settings (GPIO / pinmux config).

Can be used both on a file dump of the PIO registers for use by the fel-gpio script or natively on the device by direct mmap hardware acess.

fel and helpers

Fel is a means of talking to the Allwinner SoCs BROM over USB. You need to first active FEL mode on your device to be able to access it.

fel

Main program, which provides a script interface for talking to fel.

Usage: ./fel command arguments... [command...]
        hex[dump] address length        Dumps memory region in hex
        dump address length             Binary memory dump
        exe[cute] address               Call function address
        read address length file        Write memory contents into file
        write address file              Store file contents into memory
        ver[sion]                       Show BROM version
        clear address length            Clear memory
        fill address length value       Fill memory

usb-boot

Script for booting via USB in FEL mode. Refer to our usb boot page for more information.

fel-pio

Small binary which runs on the target. It enables IO register access over FEL mode. This should not be used directly.

fel-gpio

A script which used fel to upload fel-pio to the target, and which then can use the pio utility, and manipulate gpio settings, over fel/usb.

fel-sdboot

A small ARM native SD boot code which forces FEL mode, to boot straight into FEL mode without having to press any buttons.

jtag-loop

A small ARM native SD boot code which sets PF (CARD0) to JTAG mode and then busy-waits for you to attach with JTAG.

bootinfo

Dump information from Allwinner boot files (boot0/boot1)

        --type=sd       include SD boot info
        --type=nand     include NAND boot info (not implemented)

meminfo

This device side tool reads in register information and prints out all the information you need for adding new device support to U-Boot. This tool gets statically compiled so it can be used on Android as well.

phoenix-info

gives information about a phoenix SD image created by the phoenixcard utility and optionally extracts the embedded boot code & firmware file from their hidden partitions. Not usable for LiveSuit images.

nand-part

nand-part is a tool to repartition the internal NAND on sunxi devices. It should be (cross-)compiled for the device's architecture, and it requires the device to have a special kernel patch (already included in our kernel tree) to expose the full NAND as a block device.
