Sunxi-tools Windows — Direct Link

The 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

: The most critical tool; it puts the device into FEL mode for low-level recovery and programming via USB. sunxi-tools windows

: The most common tool, used for interacting with the processor's low-level bootrom (FEL mode) via USB. The suite is an essential set of command-line

Allwinner chips (A10, A20, H3, H5, H6, etc.) feature a low-level boot ROM routine called . When a device is powered on without a bootable SD card or NAND, it enters FEL mode and waits for instructions via USB. : The most common tool, used for interacting

These tools allow you to interact with the "FEL" mode (a low-level bootloader mode) of Allwinner chips. Key utilities include: sunxi-fexc : Converts binary configuration files ( script.bin ) to human-readable text ( script.fex ) and back again.
