Hxc-fw-installer.hex ✰

After the installer finishes writing the operational firmware, the HxC will reboot. You should see:

If your HxC no longer responds to USB DFU, an ST-Link V2 is your rescue tool.

Steps:

Before downloading and attempting to flash Hxc-fw-installer.hex, gather the following: Hxc-fw-installer.hex

  • Power Supply: Your HxC device must be powered (usually 5V via floppy power connector or USB).

    • Hxc-fw-installer.hex , you typically need to "flash" or upload it to your device using a specific software tool, as .hex files are compiled machine code used for firmware updates. Electrical Engineering Stack Exchange Since "HxC" usually refers to the HxC Floppy Emulator

    (a device that replaces old floppy drives with SD cards), here is the standard "piece" or procedure for installing it: 1. Identify Your Hardware Ensure you are using the correct hardware, such as a Gotek drive or an original HxC Floppy Emulator

    board. The firmware must match the specific microcontroller on your device (often an STM32 or ATmega chip). 2. Prepare the Software Tool Power Supply: Your HxC device must be powered

    You cannot simply "run" a .hex file on Windows or Mac. You need a dedicated "flasher" such as: STM32CubeProgrammer (for Gotek/STM32-based drives). FlashLoader Demo (for older serial updates). Cortex-M Flasher QMK Toolbox 3. Connect the Device Jumper Settings: For many Gotek drives, you must place a jumper on the pins to put the device into "Programming Mode." Connection: Connect the device to your PC using a USB-to-TTL (Serial) adapter (connect TX to RX and RX to TX). 4. Flash the Firmware Open your flashing software (e.g., STM32CubeProgrammer Select the Hxc-fw-installer.hex file in the "Open File" or "Browse" section. Choose the correct COM port for your adapter. Start Programming

    Wait for the "Verification Successful" message before disconnecting. 5. Finalize the Install

    Once the installer is flashed, remove the BOOT0 jumper. Many HxC versions then require you to place a second file (like ) on an SD card to complete the setup. Hxc-fw-installer

    Are you trying to upgrade a Gotek drive specifically, or are you working with a different hardware board? How to program a HEX file to the STM32F4 Discovery Board

    ⚠️ 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.

    Open STM32CubeProgrammer. Under "External Loader", select "ST-Link". Click "Connect". The software should detect your HxC's STM32 chip and display its memory map.

    To flash a .hex file, the device must be in "Bootloader" mode or you must use the software's built-in update feature.
