Setup Tool Environment (Windows)
The flash programming process is performed over a USB connection between the target board and the host computer containing the image.
To do so, you need to install AIoT tools. It is a set of tools to configure or interact with MediaTek AIoT boards.
You must use a Linux host computer to build the AIoT Yocto image. The Windows tool environment can only be used for flashing the board and connecting to the board.
To install AIoT Tools on a Windows host, you need:
Git 1.8 or later
Python 3.8 or later
pip3 20.3 or later
fastboot 31.0 or later
Visit https://gitforwindows.org/ to download and install git for Windows.
After installation, open the git bash program and execute the following configuration commands:
git config --global http.sslBackend schannel git config --global credential.helper manager-core
This configures git to use Windows default credentials and secure connection channels.
The Google USB Driver contains both device drivers for
fastboot on Windows.
AIoT Tools require the fastboot device driver to be properly installed.
adb can be used to connect to the board once it has been flashed with rity-demo-image.
To install these two drivers:
Download Google USB Driver from https://developer.android.com/studio/run/win-usb
Extract the downloaded zip file. The filename should be similar to
In the extracted directory, locate the file
Right-click on the file
android_winusb.infand select Install from the context menu:
Confirm the pop-up dialog.
For details, please refer to https://developer.android.com/studio/run/oem-usb#InstallingDriver
The fastboot device driver is categorized as Android Device > Android Bootloader Interface in Windows.
The fastboot device driver may not be properly detected until you actually connect the board and enter download mode. You might have to manually assign the “Unknown Device” as an Android Bootloader Device. Please refer to the troubleshooting page to do so.
fastboot program also requires separate installation.
Download SDK Platform-Tools for Windows and unzip the package
Add the unzipped directory to
Check if it is properly installed by following commands:
The version should be greater than 31.0.
Follow these steps:
- Download and install Python 3.9 from https://www.python.org/downloads/release/python-3912/.
Make sure you’ve ticked the Add Python to environment variables or Add Python to PATH checkbox:
There are known issues reported for Python 3.10 on Windows platform when installing aiot-tools. If you use Windows, we recommend you to install Python 3.9.
- Launch a Command Prompt as administrator. To do so:
Windows+Rto open the Run dialog
cmdinto the box and then press
Ctrl+Shift+Enterto run the command prompt as an administrator.
Make sure the version of
pip3 is greater than 20.3:
pip3 --version pip 21.2.4 from c:\python39\lib\site-packages\pip (python 3.9)
If your windows console cannot locate
pip3, add the Python installation path and script path to your
PATH environment variable, in some cases these paths are located in:
If you are behind a corporate firewall, you might want to install additional packages to make sure Python can correctly process additional certificates:
pip3 install python-certifi-win32 --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host gitlab.com
After installation, add the following environment variable to your Windows system:
setx REQUESTS_CA_BUNDLE %LOCALAPPDATA%\.certifi\cacert.pem set REQUESTS_CA_BUNDLE=%LOCALAPPDATA%\.certifi\cacert.pem
Please use DOS Prompt or Power Shell for this operation, since git bash or cygwin would intepret
\ as escape characters instead of path separators.
There are both
setx here becuase
setx only take effective on a new session, while
set doesn’t change the global environment variables.
Run following command as administrator to install AIoT Tools:
cd %USERPROFILE% c: pip3 install -U -e "git+https://gitlab.com/mediatek/aiot/bsp/aiot-tools.git#egg=aiot-tools"
Please note that
aiot-tools will be downloaded to your current working directory first, before being installed into your system.
Access Token as Password
Please use the generated access token instead of gitlab.com login password, if you’ve been prompt to input gitlab username and password when installing aiot-tools.
If you encountered installation errors such as missing
setuptools_scm, you can install the packages first with following commands:
pip3 install wheel setuptools_scm gpiod libusb1 packaging pyserial pyftdi pyusb pyyaml pyparsing enum34 oyaml windows-curses --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host gitlab.com
And then install AIoT Tools from gitlab.com again.
Check if it is properly installed with following commands:
The version should be greater than 1.2.
You can check your installation with
aiot-config fastboot: OK
In case your environment is not setup correctly, the tool provides you some instructions on how to correctly configure it.
For Windows users, you need to install the driver for the USB-to-UART chip on the development boards.
Here is a list of development boards and corresponding USB-to-UART chip driver you need to install:
i1200 Demo Board
For other boards, please refer to the board user guide or datasheet.
