Key features

• The real cross platform. Linux, Windows, MacOS(not test yet)
• Multi devices program support
• Daemon mode support
• Few dependencies (only libusb, zlibc, libbz2)
• Firmware (uboot/kernel) uses WCID to auto load the winusb driver on the Windows side. Windows7 users need to install the winusb driver from https://zadig.akeo.ie/ Windows10 will install the driver automatically.

Examples:

  uuu u-boot.imx            Download u-boot.imx via HID device

  uuu list.uu               Run all the commands in list.uu

  uuu -s                    Enter shell mode. Input command.

  uuu -v u-boot.imx         verbose mode

  uuu -d u-boot.imx         Once it detects the attachment of a known device, download boot.imx.

                            u-boot.imx can be replaced, new file will be download once board reset.

                            Do not unplug the SD card, write to the SD card, nor plug in a SD card when debugging uboot.

  uuu -b emmc u-boot.imx    write u-boot.imx to emmc boot partition. u-boot.imx need enable fastboot

  uuu -b emmc_all wic.zst   decompress wic.zst file and download the whole image into emmc

Prebuilt Image and pdf document

The prebuilt image and document are here:

• https://github.com/nxp-imx/mfgtools/releases
• ubuntu 22.04, 'apt-get install uuu'
• UUU.pdf is snapshot of wiki

How to Build:

Windows

• git clone --recurse-submodules https://github.com/nxp-imx/mfgtools.git
• cd mfgtools
• open msvs/uuu.sln with Visual Studio 2017

Visual Studio

Note that, since uuu is an OSI compliant Open Source project, you are entitled to download and use the freely available Visual Studio Community Edition to build, run or develop for uuu. As per the Visual Studio Community Edition license this applies regardless of whether you are an individual or a corporate user.

Linux

• git clone https://github.com/nxp-imx/mfgtools.git
• cd mfgtools
• sudo apt-get install libusb-1.0-0-dev libbz2-dev libzstd-dev pkg-config cmake libssl-dev g++ zlib1g-dev libtinyxml2-dev
• cmake . && make

The above commands build mfgtools in source. To build it out of source (requires cmake 3.13 or newer):

• cmake -S . -B build
• cmake --build build --target all

For cmake prior 3.13:

• mkdir build && cd build
• cmake .. && make

macOS

• git clone https://github.com/nxp-imx/mfgtools.git
• cd mfgtools
• brew install cmake libusb openssl pkg-config tinyxml2
• cmake -DOPENSSL_ROOT_DIR=$(brew --prefix)/opt/openssl . && make

Note that we assume homebrew is installed and can be used to resolve dependencies as shown above. The remaining dependency libbz2 can be resolved via the XCode supplied libraries.

Note if you meet "can't detach kernel driver" try to check libusb version.

brew info libusb
==> libusb: stable 1.0.26 (bottled), HEAD

Run environment

• Windows 10 64 bit
• Linux (Ubuntu) 64 bit
• macOS (Catalina)
• 32 bit systems will have problems with big files.

Python bindings

We also provide Python bindings for libuuu to enable integration of functionality from uuu into your code. For more information see wrapper.
