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.
The hxc-fw-installer.hex file is the unsung hero of the HxC ecosystem. It’s the master key that unlocks, repairs, and updates your floppy emulator. Whether you are reviving a vintage Amiga 500, an Atari ST, or a classic Roland sampling keyboard, mastering this HEX file transforms a confusing technical hurdle into a simple, repeatable process.
Key takeaways:
✔️ Always match the HEX file to your exact HXC hardware revision.
✔️ Use DFU mode for Rev C; use ST-Link for bricked boards.
✔️ After flashing the installer, immediately load the main firmware.
✔️ Keep a local backup of the latest hxc-fw-installer.hex.
By following this guide, you ensure that your HxC Floppy Emulator runs reliably for years—keeping the retro computing spirit alive without the click of death from a dying floppy drive.

Hxc-fw-installer.hex bootloader installation file used to convert a standard Gotek floppy emulator into a version capable of running HxC Floppy Emulator firmware Purpose and Function This specific
file is required for the initial "hard-flashing" of a Gotek drive's microcontroller (typically an Artery AT32
chip). Once this installer is flashed to the device, it provides the HxC bootloader
, which allows you to perform all future firmware updates easily via a simple USB thumb drive. How to Use It Preparation : You must obtain this file directly from the HxC2001 website , often via a small one-time payment for the license. Connection : Connect the Gotek to your PC using a USB-A to USB-A cable Serial TTL adapter
Set the drive into "programming mode" (often by bridging the Use software like STM32 Dfuse Artery ISP Programmer to select the hxc_fw_installer.hex file and flash it to the device. Finalizing : After the Hxc-fw-installer.hex
file is flashed, you must place the actual firmware update file (usually ending in EXCHANGE.BIN
file on a FAT32-formatted USB stick to complete the installation. Common Issues Missing File
: Users often cannot find this file in standard firmware zip archives because it is specifically provided via an automated email after registering your device with the developer. Wrong Format
: Depending on your hardware version, you might see this file as hxc_fw_installer.dfu instead of needed to flash this file? HxC bootloader installation - HxC2001
Hxc-fw-installer.hex is a specialized firmware file used to update or install the HxC Floppy Emulator firmware onto compatible hardware devices. It acts as a bridge, allowing older hardware that relies on physical floppy disks to use modern SD cards or USB drives for data storage. What is Hxc-fw-installer.hex?
The file is a compiled binary in Intel HEX format. It contains the machine code necessary to program a microcontroller—typically the Atmel ATmega series found in Gotek drives or original HxC hardware.
Primary Function: To transform a standard, inexpensive floppy emulator into a high-performance HxC-compatible device.
Target Hardware: Most commonly used with Gotek SFR1M44-U100 drives.
The "Bootloader" Role: It often serves as the initial installer that places the HxC bootloader onto the chip, enabling subsequent USB-based firmware updates. Why Users Install This Firmware
Standard floppy emulators often have limited compatibility and poor interfaces. Installing the HxC firmware via this HEX file provides several advantages: Plug your ST-Link V2 into a USB port
Massive File Support: Supports .HFE, .ADF, .ST, .IMG, and many other legacy formats.
Broad Compatibility: Works with Amiga, Atari ST, Amstrad CPC, vintage PCs, and industrial equipment (like CNC machines or musical samplers).
OLED Support: Enables the use of OLED screens and rotary encoders for easier file navigation.
Stability: Offers a more robust file-system handling compared to "stock" factory firmware. The Installation Process
Using Hxc-fw-installer.hex is not as simple as copying a file to a USB drive. Because it overwrites the core logic of the hardware, it requires a "flashing" procedure. 🛠️ Hardware Requirements USB-to-TTL Adapter: Needed to connect the emulator to a PC.
Jumper Wires: To bridge the programming pins on the emulator board.
Programming Software: Tools like STM32CubeProgrammer or Flash Loader Demo are used to push the HEX file to the device. ⚠️ Critical Considerations
Licensing: The HxC firmware is "donationware." You typically need to purchase a license from the HxC 2001 official site to receive the specific version of the installer linked to your hardware's ID.
Risk of Bricking: Interrupting the power during the flash process can render the emulator unusable.
Soldering: Some older models may require soldering header pins to the circuit board to establish a connection. Outcome of a Successful Flash Double-check every connection
Once the HEX file is successfully installed, the emulator's behavior changes immediately. Upon reboot, the device will typically look for a HXCSDFE.CFG file on your USB drive or SD card. This configuration file allows the emulator to index your disk images and display them on the drive's internal 7-segment or OLED display.
If you are looking to revitalize a vintage computer or an industrial machine, this file is the key to moving away from failing physical floppy disks and into a reliable digital workflow.
⚠️ Important: This guide assumes you have a device already running HxC firmware (or a bootloader) and you want to update it. Flashing the wrong firmware can brick your device. Double-check your hardware model.
Since you didn’t specify your exact device model (e.g., HxC2001, HxC Rev C, Gotek with HxC), I recommend checking the official HxC Floppy Emulator forum or the HxC_Firmware_User_Manual.pdf that came with your download. If you share your hardware details, I can give more precise steps.
Based on the filename Hxc-fw-installer.hex, this guide pertains to the HxC Floppy Emulator (specifically the SD Card HxC Floppy Emulator hardware). This file is a firmware update utility used to flash the internal memory of the emulator device.
Below is a comprehensive guide on how to use this file.
Cause: The SD card slot has a poor connection, or the card is not formatted as FAT32 (or MBR partition table).
Solution: Reformat the SD card using SD Card Formatter. Use a 4GB or smaller card for best compatibility.
Cause: Missing drivers or the HxC isn’t in DFU mode.
Solution:
The installation process depends on your hardware interface. Below are the three most common methods.
