Sunxi-tools allow low-level access to Allwinner hardware. The suite includes several critical utilities:
Once those prerequisites are satisfied, the same powerful FEL protocol commands work seamlessly in a Windows command prompt, giving you full, low-level control over your Allwinner device. Whether you're recovering a bricked board, prototyping a new system, or just exploring the hardware, sunxi-tools on Windows is an indispensable tool in your embedded development arsenal. sunxi-tools windows
You have two options for getting the binaries (like sunxi-fel.exe and sunxi-nand-part.exe ): Sunxi-tools allow low-level access to Allwinner hardware
In this example, sunxi-fel -p writes u-boot-sunxi-with-spl.bin to the SPI flash at memory address 0. You have two options for getting the binaries
Before diving in, you need two things:
| Tool | Best for | Pros | Cons | | :--- | :--- | :--- | :--- | | | Beginners, standard firmware updates, and users who want a graphical interface. | Easy to use, GUI-based, officially supported by Allwinner, integrates USB drivers. | Limited flexibility, not suitable for low-level debugging, can be picky with USB cables and drivers. | | Sunxi-tools | Developers, advanced users, scripting, low-level debugging, and custom bootloader work. | Highly flexible, scriptable, offers granular control, open-source, direct hardware access. | Command-line only, requires manual driver setup, steeper learning curve. | | XFEL | Developers seeking a modern, cross-platform FEL tool, often with better support for newer Allwinner chips. | Cross-platform, modern codebase, actively maintained. | Less documentation and community support compared to the older sunxi-tools . |
This will produce the sunxi-fel.exe file in the directory. To use it conveniently from any command prompt, add that directory to your system's PATH environment variable.
