Hxc-fw-installer.hex

hxc-fw-installer.hex is the Intel HEX firmware installer file used to update or install firmware on the HxC Floppy Emulator family of devices (commonly HxC Floppy Emulator boards, Gotek-based emulators, and related hardware). The HxC Floppy Emulator is a device that emulates floppy disk drives by reading disk images (ADF, IMG, DSK, etc.) from USB drives or SD cards and presenting them to legacy hardware.

  • For Gotek with HxC firmware:

    • Plug your ST-Link V2 into a USB port. Use jumper wires to connect:

    Double-check every connection. A reversed SWDIO/SWCLK will fail silently.

    With newer HxC models (e.g., HxC Gotek version, HxC Rev F), the firmware update process has become more streamlined. Some now use a single .bin file updated directly from an SD card, bypassing the need for a separate installer HEX.

    However, the installer remains critical for recovery. Even the latest devices have a hidden “emergency mode” that expects an Intel HEX file over USB or serial. So, always keep a copy of the appropriate hxc-fw-installer.hex stored safely on your PC or cloud drive. Hxc-fw-installer.hex

    This guide assumes you have an STM32-based HxC Rev C or newer (the most common today). Always disconnect power before connecting cables.

    For hardware hackers and developers, hxc-fw-installer.hex is not a black box. The source code for earlier bootloaders was released under a non-commercial license. You can:

    To rebuild:

    But for 99% of users, the pre-compiled official file is all you need. hxc-fw-installer

    A common mistake new users make is assuming that dragging Hxc-fw-installer.hex onto an SD card will update the device. It will not.

    The .hex file is intended for direct communication with the HxC’s processor via a hardware programmer (like an ST-Link, USB Blaster, or Arduino-as-ISP) or the HxC’s own USB bootloader mode. The HxC cannot read a .hex file from an SD card because the SD card reader itself requires firmware to function—a classic chicken-and-egg problem.

    To use Hxc-fw-installer.hex, you must bypass the SD card entirely.

    If your device already runs an older HxC firmware, you can update via USB stick: For Gotek with HxC firmware:

    This method only works if the current firmware supports USB updates.
