Command line utilities to work with devices based on Allwinner SoCs: sun4i, sun5i, ... - that's why the 'x' in the package name.

sunxi-fexc

.fex file (de)compiler

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

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

bin2fex

compatibility shortcut to call sunxi-fexc to decompile a script.bin blob back into .fex format used by Allwinner's SDK to configure the boards.

fex2bin

compatiblity shortcut to call sunxi-fexc to compile a .fex file into the binary form used by the legacy 3.4 kernel ("linux-sunxi").

sunxi-fel

script interface for USB communication with the FEL handler built in to the CPU. You usually activate FEL mode by pushing the uboot / recovery button at poweron, or by having your device "fail over" to FEL when no other boot option is available. See http://linux-sunxi.org/FEL/USBBoot for a detailed usage guide.

When called with no arguments, sunxi-fel will display a short usage summary.

Note: Unless you select a specific device using the --dev or --sid options, the tool will access the first Allwinner device (in FEL mode) that it finds. You can print a list of all FEL devices currently connected/detected with ./sunxi-fel --list --verbose.

fel-gpio

Simple wrapper (script) around sunxi-pio and sunxi-fel to allow GPIO manipulations via FEL

fel-sdboot

ARM native sdcard bootloader forcing the device into FEL mode

uart0-helloworld-sdboot

ARM native sdcard bootloader, which is only printing a short "hello" message to the UART0 serial console. Because it relies on runtime SoC type detection, this single image is bootable on a wide range of Allwinner devices and can be used for testing. Additionally, it may serve as a template/example for developing simple bare metal code (LED blinking and other similar GPIO related things).

sunxi-pio

Manipulate PIO registers/dumps

sunxi-nand-part

Tool for manipulating Allwinner NAND partition tables

sunxi-nand-image-builder

Tool used to create raw NAND images (including boot0 images)

jtag-loop.sunxi

ARM native boot helper to force the SD port into JTAG and then stop, to ease debugging of bootloaders.

sunxi-bootinfo

Dump information from Allwinner boot files (boot0 / boot1)

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

phoenix_info

gives information about a phoenix image created by the phoenixcard utility and optionally extracts the embedded boot code & firmware file from their hidden partitions.

sunxi-meminfo

Tool for reading DRAM settings from registers. Compiled as a static binary for use on android and other OSes. To build this, get a toolchain and run:

make CROSS_COMPILE=arm-linux-gnueabihf- sunxi-meminfo

sunxi-script_extractor

A simple tool, which can be executed on a rooted Android device to dump the script.bin blob from RAM via reading /dev/mem. To build this, get a toolchain and run:

make CROSS_COMPILE=arm-linux-gnueabihf- sunxi-script_extractor

Building

Compilation requires the development version of libusb-1.0 (include header and library) to be installed for sunxi-fel. Unless you explicitly pass LIBUSB_CFLAGS and LIBUSB_LIBS to the make utility, pkg-config is also needed.

Available build targets:

  • make tools builds tools that are useful on the host. This is what most people will want, and our default target (when simply using make).

  • make target-tools builds tools that are intended for the target (Allwinner SoC), using a cross-compiler. The Makefile will try to auto-detect a suitable toolchain prefix, and falls back to arm-none-eabi- otherwise. If needed, you may override this by explicitly setting CROSS_COMPILE.
    Hint: When compiling 'natively' on the target platform you may simply use an empty toolchain prefix here (make target-tools CROSS_COMPILE= or make all CROSS_COMPILE=).

  • make all builds both tools and target-tools.

  • make install-tools builds tools and then copies/installs them to a filesystem location. The destination is affected by settings for DESTDIR, PREFIX and possibly BINDIR. For details, please refer to the Makefile. You may use make install as a shortcut for this.

  • make install-target-tools builds target-tools and then copies/installs them to a filesystem location selected by DESTDIR, PREFIX and possibly BINDIR - see make install-tools above.

  • make install-all builds and installs both tools and target-tools.

  • make misc builds miscellaneous (host) utilities that are not part of our 'standard' suite. Currently this means phoenix_info and sunxi-nand-image-builder.

  • make install-misc builds misc and installs the resulting binaries.
