The most critical prerequisite for using SunxiTools on Windows is proper USB driver configuration. The FEL mode requires low-level USB access, which Windows doesn't provide by default. Here's how to set it up:
: Used to read and analyze information from the bootloader header. Portable Version Advantages
Download the latest compiled binary archive of sunxitools-win32 or sunxitools-win64 from a trusted open-source repository (such as GitHub). sunxitools windows portable
Drop down the device list and locate your Allwinner device (it often appears as Unknown Device , USB Device (VID_1f3a_PID_efe8) , or AW-FEL ). In the driver selection box, select or WinUSB .

Fix: Connect the USB cable to a rear motherboard port (USB 2.0 is often more stable than USB 3.0 for legacy Allwinner flashing). Avoid external USB hubs. Conclusion
Converts a plain-text .fex hardware configuration file into a binary .bin format (often named script.bin ) that the device bootloader can read. fex2bin script
SunXiTools is a comprehensive toolkit that offers a wide range of functionalities aimed at diagnosing, troubleshooting, and repairing various issues that may arise in Windows systems. Developed with the objective of providing IT professionals and enthusiasts with a versatile set of tools, SunXiTools covers a broad spectrum of tasks. These include data recovery, disk imaging, password resetting, and system cleanup, among others. The suite is designed to be user-friendly, allowing individuals with varying levels of technical expertise to navigate and utilize its features effectively.
For developers who want the absolute latest features or need to customize the tools, building from source is a viable option using MSYS2.
Many older legacy Allwinner kernels rely on Script.bin configurations rather than modern Device Trees. If you need to enable a disabled hardware feature (like a specific GPIO pin or UART port):
简单来说， sunxi-fel 的作用相当于其他 ARM 平台的 JTAG 或 DFU 模式，但使用起来更简便。开发者无需昂贵的仿真器，仅需一根 USB 线即可向设备 RAM 加载程序或直接烧录到 Flash 中。
