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 ] [-O ] [ [ ]]

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

When no arguments are provided, it waits on stdin. Similar, when no   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 first need to activate 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 [options] command arguments... [command...] -v, --verbose                  Verbose logging

spl file                       Load and execute U-Boot SPL If file additionally contains a main U-Boot binary (u-boot-sunxi-with-spl.bin), this command also transfers that to memory (default address from image), but won't execute it.

uboot file-with-spl            like "spl", but actually starts U-Boot U-Boot execution will take place when the fel utility exits. This allows combining "uboot" with further "write" commands (to transfer other files needed for the boot).

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
Legacy script for booting via USB in FEL mode, no longer used. 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.

= script-extractor =

This device side tool reads the script.bin data from RAM at the magic address 0x43000000 and saves it to a file. This tool gets statically compiled so it can be used on Android as well. Please note that it is only usable with FEX based kernels (as used in the stock Android firmware) and does not make any sense with the devicetree based mainline kernel.

= 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.
