sunxi-tools

Prerequisites

• libusb-1.0 (e.g. on a debian system do a apt-get install libusb-1.0-0-dev)
• pkg-config

Building

If not stated otherwise:

make

Tools

bin2fex

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

fex2bin

compatibility shortcut to call 'fexc' to compile '.fex' file into the binary form used by the sun4i kernel

fexc

base program of the two aforementioned

bootinfo

Dump information from Allwinner boot files (boot0/boot1)

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

fel

script interface for talking to the FEL USB handler built in to the CPU. You activate FEL mode by pushing the usboot/recovery button at poweron.

fel-gpio

Simple wrapper around fel-pio and fel to allos GPIO manipulations via FEL

fel-pio.bin

ARM native helper for fel-gpio

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.

pio

Manipulate PIO register dumps

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.
