Open source firmware and utilities for Minipro TL866xx series of chip programmers

This project's scope is dealing with the firmware within the TL866 itself. It includes software for dumping, reprogramming, and manipulating the firmware. Schematics and discussion of internal operations are also here.

Also here you can find a linux USB wrapper for TL866 and TL866II which make these programmers native software to work with Wine. The wrapper is located in wine folder.

Installation of the TL866 Updater on Linux

Install build dependencies


sudo apt-get install build-essential pkg-config git libusb-1.0-0-dev libqt4-dev

Checkout source code and compile

git clone
cd TL866/TL866_Updater/QT
sudo cp TL866_Updater /usr/local/bin

Udev configuration (recommended)

If you want to access the programmer as a regular user, you'll have to configure udev to recognize the programmer and set appropriate access permissions. These are the same rules as are available with If you already installed the rules there, you don't need to do it again here.


sudo cp udev/debian/60-minipro.rules /etc/udev/rules.d/
sudo udevadm trigger

You'll also have to add your regular user to the plugdev system group:

sudo usermod -a -G plugdev YOUR-USER

Note that this change will only become effective after your next login.

CentOS 7

sudo cp udev/centos7/80-minipro.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules

The CentOS rules file currently make the programmer device writable for all users.


Follow instructions for Linux. You'll need pkg-config, libusb, and libqt4 or above through a package installer. Macports and Homebrew have been used successfully. Udev doesn't exist for macOS so native IOKit is used instead.

Homebrew instructions:

brew install qt libusb pkg-config
git clone
cd TL866/TL866_Updater/QT
cp -R /Applications
You can’t perform that action at this time.
