sunxi-tools is a collection of utilities for Allwinner (sunxi) SoC devices—useful for reading/writing flash, creating images, and working with boot headers (e.g., nand-part, sunxi-fel, nand-sata-install). Official development is Linux-focused; Windows support requires workarounds.
Allwinner ARM-based processors are widely used in single-board computers (e.g., Orange Pi, Banana Pi) and embedded devices. The sunxi-tools project provides utilities such as sunxi-fel (to communicate via USB FEL mode), sunxi-nand-part, and sunxi-pio. However, these tools rely on Linux-specific system calls (e.g., libusb, ioctl, FTDI). Consequently, Windows users must employ compatibility layers or porting strategies. sunxi-tools windows
