Hello all,
Quite regularly I’m asked how to flash a Gotek floppy drive emulator with HXC firmware so I wrote this walkthrough. I’ve tried to keep it as short and clear as possible. If any mistakes or shortcoming have occurred, please inform.
Needed:
- Gotek USB floppy emulator SFR1M44-U100K or SFR1M44-U100
- USB-TTL converter
- HXC firmware licence
- 32bit windows PC
- Soldering iron
- Wire
- Prepared USB flash drive
Prepare USB flash drive with latest HXC firmware:
Format FAT32
Download latest HXC firmware from HXC download area or use direct download link: HXCFEUSB_HFE_beta_firmware.zip. Unzip and copy the .UPD file onto the USB flash drive. For example: HxCFEUSB_V3_4_11_2a.UPD
Open the Gotek. 3 screw located at arrows:
Pull out PCB: lift backside (connector side) and pull back while gently pushing the LED. Then push display to the right:
Solder a small piece of wire across points shown in pic. This sets Gotek in system bootloader mode:
Buy an USB-TTL adapter. You’ll find these on ebay of whatever electonics webshop cheaply.
Connect USB-TTL converter to Gotek:
Connect USB-TTL to a Windows computer with internet.
Now you have to but a HXC firmware licence here: https://hxc2001.com/store/
Pay by paypal 10,- + VAT and you’ll get one licence to flash one Gotek.
Download the STM32_SerialBridge.zip file, unpack (one .exe and ond readme) and open the SecSerialBridge.exe file. (btw: readme.txt is another walkthrough).
Mind the fact you’ll need a 32 bit Windows PC!
This won’t run in a 64 bit windows machine or Apple.
Use your login credentials, click connect and you’ll see you’ve got one licence (if you bought one) left. Select COM port which carries the USB-TTL converter and click “program”.
Be patient ..
little more patient…
[completed]
Now close program.
Remove USB-TTL converter from PC.
Remove green, blue and yellow wires from Gotek.
Insert USB-TTL converter back into PC (so Gotek gets powered).
Gotek Display will show: LDR
Put in the prepared USB flash drive with Firmware and wait until Gotek finished installing the firmware.
Gotek Display will now show: HXC.
