Awutils

AllWinner Utils or AWUtils is an abandoned set of tools for handling Allwinner images

• awflash - flash devices over USB
• awimage - pack/unpack images
• log2bin - convert filtered UsbSnoop log data to binary file

These tools were initially intended to allow for livesuit like flashing of devices, but this project was abandoned.

Download

Sources can be obtained from Ithmar's github repository and 'make' should work to build it.

git clone git://github.com/Ithamar/awutils.git
cd awutils
make

You might need some developer libraries for USB like libusb-dev

Usage

Usage is quite straight forward, 'awimage -v image.img'.

Output should look something like this:

You can then enter the newly created directory image.img.dump and explore.

Filelist.txt is a summary of what was found (similar to what is above).

Status

July 2014:

• awflash - not compilable (patched version requires also pkg-config)
• awimage - packing triggers error (bypass), unpacked-then-packed and original images are differs
