def detect_device(): # Simpler: check for typical LibreTech eMMC if os.path.exists("/dev/mmcblk2"): return "/dev/mmcblk2" elif os.path.exists("/dev/sda"): return "/dev/sda" # Caution: could be system disk else: sys.exit("No supported device found.")

A: natively? No. The USB low-level timing requirements fail on macOS. On Windows, you must use WSL2 with USB/IP passthrough (advanced). A dedicated Linux live USB is strongly recommended.

# 1. Identify your target disk (e.g., /dev/sdX or /dev/mmcblkX) # WARNING: Selecting the wrong disk will erase your data! lsblk # 2. Unmount the target drive if it automounted sudo umount /dev/sdX* # 3. Use xz and dd to decompress and flash simultaneously # This streams the file directly, saving disk space and ensuring block accuracy xz -d -c /path/to/libretech-image.img.xz | sudo dd of=/dev/sdX bs=4M status=progress conv=fsync Use code with caution. Advanced: Flashing the Bootloader Separately

Using the specialized libretech-flash-tool eliminates the guesswork of setting up a Libre Computer single-board device. By automating the alignment of bootloaders and partitioning, it saves time and prevents common boot failure frustrations associated with generic image burners. libretech-flash-tool
