Let’s walk through a typical workflow for booting a device in FEL mode and writing to its memory.
For Windows users, is a "must-have but handle with care" utility. It is indispensable for low-level "fel" mode operations that GUI tools like PhoenixSuit can't handle. However, if you are doing heavy development, using these tools via WSL2 (with USBIPD for device attachment) often provides a more stable and feature-complete experience than the standalone Windows .exe versions.

This article provides a complete guide on how to obtain, install, and use sunxi-tools on Windows 10 and 11 to flash firmware, dump NAND, and interact with the processor. What are Sunxi-Tools?
Select your Allwinner device from the dropdown menu (it typically appears as , "Allwinner FEL" , or displays the USB ID 1f3a:efe8 ). sunxi-tools windows
: Connect your board to your PC via USB while holding the FEL button (or shorting specific pins, depending on your hardware). : Download and run the Zadig USB tool
Choose the or libusbK driver and click "Install Driver" or "Replace Driver". Practical Applications on Windows Modifying FEX Files
Boot your Allwinner device into and connect it to your PC via a USB cable. Let’s walk through a typical workflow for booting
is an indispensable collection of command-line utilities for anyone working with Allwinner SoC-based devices (like the Orange Pi, NanoPi, or Pine64). While natively built for Linux, you can absolutely run them on Windows to flash bootloaders, edit FEX files, or use FEL mode. 1. Choose Your Environment There are two main ways to run these tools on Windows:
Entering FEL mode ensures the device is ready for communication. The typical method involves holding down a specific boot button while connecting the USB cable to the PC. For some boards, shorting specific pins on the SPI flash during power-up can also trigger the mode.
Install the required build tools and dependencies (including libusb for USB communication): pacman -S git make gcc pkg-config libusb-devel Use code with caution. Clone the official sunxi-tools repository: git clone https://github.com cd sunxi-tools Use code with caution. Compile the tools: make Use code with caution. However, if you are doing heavy development, using
is a collection of open-source command-line utilities designed for hacking, configuring, and flashing devices built on Allwinner SoCs (System on Chips) . While these tools were natively born in the Linux ecosystem, running them on Windows is entirely possible and highly useful for developers, hobbyists, and tech enthusiasts working with single-board computers, tablets, or retro gaming handhelds.
To use tools like sunxi-fel , your device must be in (usually achieved by holding a specific button during power-up). Connect your device to your PC via USB. Open Zadig . Select Options > List All Devices .
