The sunxi-tools suite is an essential set of command-line utilities for developers and hobbyists working with Allwinner SoC (System on Chip) based ARM devices, such as the Orange Pi, NanoPi, and Pine64. While these tools are natively developed for Linux, they are fully functional on Windows with the right environment, allowing users to flash firmware, manipulate hardware configurations (FEX files), and interact with devices in FEL mode. Core Utilities in sunxi-tools
on Windows, your computer must recognize the Allwinner device in FEL mode. Enter FEL Mode
Device Not Found: Ensure you have performed the driver replacement in Zadig while the device is in FEL mode.
: The primary tool for communicating with the Allwinner BROM over USB. It allows you to put devices into
Troubleshooting Common Issues
(System on Chips), such as Orange Pi, Banana Pi, and CubieBoard
Once configured, you can use the terminal to interact with your hardware: Description sunxi-fel version Checks if the device is correctly detected in FEL mode. sunxi-fel spl Loads and executes a Secondary Program Loader. sunxi-fex2bin Compiles a FEX configuration file into a binary .bin. sunxi-nand-part Manages partitions on the NAND flash of Allwinner devices. 5. Troubleshooting Tips
This prints the SoC type (e.g., H3, A64) and available SRAM.
- Remove SD card, eMMC, and NAND.
- Disconnect power.
- Connect the USB OTG port to your Windows PC.
- Apply power. The device is now in FEL mode (no LEDs may flash, which is normal).
