| Issue | Likely Fix | |-------|-------------| | No chip detected | Check RX/TX crossover, GND, and 3.3V logic level. Verify BOOT0 is set. | | Flash fails mid‑way | Reduce baud rate to 9600. Recheck power supply. | | Device not booting after flash | Reflash, verify verify checksum. Ensure BOOT0 is removed. | | “Not in bootloader mode” | Short BOOT0 to VCC (3.3V) powering on, keep it shorted during flash. |

Required to connect the Gotek directly to your PC.

On your HxC PCB, find the 4-pin SWD header. It is typically labeled SWD , JTAG , or has pin markings: Hxc-fw-installer.hex

This process is primarily used for STM32/AT32-based Gotek drives, often requiring a USB-to-TTL serial adapter to flash the chip directly. Prerequisites for Installing 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. | Issue | Likely Fix | |-------|-------------| |

However, as noted in forum discussions, users have reported reaching "steps 9 & 10" of this process only to discover they cannot find hxc_fw_installer.hex . As with the serial method, this file is provided only after registration and is not publicly available. Recheck power supply

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

The HxC Floppy Emulator is not just for vintage computers. Its versatility is one of its greatest strengths.
