First time bootloader Flashing/Programming process :

All the mentioned files are in the Online Bootloader programmer archive

STM32 Based hardware bootloader Downloader and Flasher.

This software allows you to download and program the STM32 HxC bootloader into
a STM32 based floppy emulator hardware. (For example these "Gotek" or the next STM32 HxC Floppy emulator units).

Note : This Flash procedure should be needed only once per device since the STM32 HxC bootloader
will allows you to update the device with a simple USB stick. See the below post if you just want to update your HxC Gotek.


To use it you need :

:arrow: A STM32 based floppy emulator hardware to flash.

:arrow: A PC under Windows connected to Internet.

:arrow: Any 3.3V serial connection to connect the Floppy Emulator hardware to the PC.

:arrow: Your account information. Go to this page to purchase the firmware and to get your account : :arrow: http://hxc2001.com/store

To Flash the device

:arrow: Set the BOOT0 signal to the VCC3V3 on the device. (Add a connection between "J3" and the VCC3V3 pin. See below).

:arrow: Connect your serial adapter to the device and to the PC. (GND,RX,TX,+5V)
Note 1: To power the device, you can use a external +5V source or the +5V coming from your USB adapter.
Note 2: Cross connect your serial adapter to the device : TX wire to the RX pin, RX wire to the TX pin.

:arrow: Start the SecSerialBridge software and select the COM port of your serial adapter. Click on the button "Open"

:arrow: Enter the server and your contacts data. Click on the button "Connect".
If the connection to the server succeed you will get the "Link is UP !" status.

:arrow: Some seconds later you should get the "Device detected." status.
Note : If you don't get it, try to reset the STM32 by making a short connection of the reset signal (RST) to GND.

:arrow: Once the device is detected, you can press the "Program" button.
The download and programming process finish with a "Done !" Status. The whole process take some minutes.

Once done, remove all the connections previously done on the programming pins.

The device should now display "Ldr" at power up and wait for a USB flash drive with a UPD file to use.
Here it is the UPD archive with the latest firmware version .

Programming connector

The Programming connector is near the power input connector. (SFRC922,SFRC526,...)

Code: Select all

Firmware update procedure :

(The HxC bootloader is needed -> see the "Bootloader Flashing/Programming process" post above).

All the mentioned files are in the USB Stick STM32 HxC Floppy Emulator firmware update archive
NOTE : The UPD firmware files are usable when your drive have the HxC Bootloader.
See <<First Time Bootloader Flashing/Programming process>>to get it.

USB HxC Floppy Emulator Update procedure :

:arrow: Copy the new firmware file (*.upd) to a FAT32/FAT16/FAT12 USB flash device.
:arrow: Insert the USB Stick into the emulator and press both buttons.
:arrow: Power up the device and keep the buttons pressed during at least 2 seconds.
:arrow: Wait some seconds... its done !

Bootstrap error codes:

Error 1 : (blink 1 time and 2 seconds pause cycle) No entry point (->no software flashed)
Error 2 : (blink 2 time and 2 seconds pause cycle) USB init error.
Error 3 : (blink 3 time and 2 seconds pause cycle) FAT error.
Error 4 : (blink 4 time and 2 seconds pause cycle) UPD File not found!
Error 5 : (blink 5 time and 2 seconds pause cycle) Bad UPD File header! (bad file)
Error 6 : (blink 6 time and 2 seconds pause cycle) Bad data crc! (file corrupted)
Error 7 : (blink 7 time and 2 seconds pause cycle) Bad data size!
Error 8 : (blink 8 time and 2 seconds pause cycle) Write error (STM32 flash error)

Usage instructions :

All the mentioned files are in the USB Stick STM32 HxC Floppy Emulator firmware update archive
General STM32 HxC Floppy Emulator Firmware Usage: -

:arrow: Format the USB Stick in FAT32 (FAT12 & FAT16 also supported).
:arrow: (Optional if you have an LCD/OLED screen) Copy the right HXCSDFE.CFG file to the root of the USB Stick
(See "Mode selection" below for more details).
:arrow: Copy or generate your disks images to the USB Stick. (See "File images supported" below for mode details).
:arrow: Insert the USB Stick into the emulator.

Mode selection

There are actually three modes available :

Normal mode

In this mode the file image/disk to load is directly selected with the buttons
and the LCD screen. One I2C screen is needed to be able to use this mode.
An optional "select" push button can be connected on the JA connector.
No extra software needed.

config file is optional (Config-Less support).

If you you want to have the last image selection image feature, the config file to copy to the root of the flash media
for this mode is into the folder Config_Files/Normal_mode/HXCSDFE.CFG from the
USB Stick STM32 HxC Floppy Emulator firmware update archive

Indexed mode

In this mode the file images must be named DSKA0000.HFE, DSKA0001.HFE, DSKA0002.HFE,...
The 2/3 digits display shows the actual file number selected.

No LCD and/or extra push button is needed to use this mode.
No extra software needed.

This is the recommended mode when you don't have the extra LCD & button and when
your machine can't use the autoboot mode (see below).

The config file to copy to the root of the flash media for this mode :

Config_Files/Indexed_mode/HXCSDFE.CFG from the USB Stick STM32 HxC Floppy Emulator firmware update archive

"Autoboot" / File selector mode

In this mode, the AUTOBOOT.HFE software is used to select the images to load
directly on the computer.
This software is actually available on Amiga, Atari ST and CPC computers.

No LCD and/or extra push button is required to use this mode, but the LCD may help you
to see which disk is actually mounted.

The config and the software file to copy to the root of the flash media for this mode :

http://hxc2001.com/download/floppy_driv ... anager.zip

Internal parameters settings :
There is many parameters that can be changed. You generally don't have to change
them as the default values are fine in most cases.

Anyway if needed, these settings can be changed with the internal menu.

To access the setting menu, remove the USB stick and press both buttons. Then you can navigate
through the various available options.

This menu is available with both LCD/OLED and 7 Segments Gotek drive.

The file selectors have also a setting page that can be used to change these
parameters.

:arrow: OLED/LCD Gotek Menu :

Here is some of the available parameters :

- Floppy Interface mode (predefined modes and custom modes).

- System Family selection.

- Single or Double step track mode.

- Emulation Bitrate (Auto or forced).

- Floppy write protect state.

- Step Sound output settings.

- LCD/OLED characters per line setting (16/18/20/21 or 40 characters per line).

- LCD Backlight timeout setting.

- Select Button emulation (on/off and timeout setting)

Note : To clear/reset all settings to the default values, press the right button at power up.

:arrow: Original 7 Segments Gotek Menu :

-> To access it, remove the USB Stick and press both buttons.
--> Choose the sub menu number - wait some seconds for the selection validation.
---> Check and/or change the setting - wait some seconds for the selection validation.

The new setting is then saved into the device.

Optional Add-on : I2C SSD1306 128x32 OLED LCD Screen

Note : Since the 3.0.26.1a, update your firmware if needed.

You can connect an SSD1306 based 128x32 OLED screen.

These screens are compatible with this firmware : http://www.ebay.com/itm/302110929185 ( IIC Interface ! )

You can connect the screen directly to the J7 connector. (additional pull-up resistors NOT required.)

- GND, VCC 3.3V, SCL and SDA position on J7

Code: Select all

Optional Add-on : I2C LCD Screen

These kind of I2C LCD board is compatible with the firmware :

http://www.ebay.com/itm/IIC-I2C-TWI-SP- ... 484f235c20
(board only - without the LCD)

http://www.ebay.com/itm/IIC-I2C-TWI-SPI ... 258afcd8e4
(board only - without the LCD)

http://www.ebay.com/itm/New-Blue-IIC-I2 ... 338ed80545
(board + LCD)

http://www.ebay.com/itm/IIC-I2C-TWI-SP- ... 484f1ed4cd
(board + LCD)

Any I2C address is supported : The firmware scan automatically the I2C bus at power up (0x20-0x27 and 0x38-0x3F address range scanned)
So there is no specific requirement about the I2C address setting.

To connect the I2C LCD, you have to connect SDA & SCL at the J7 connector (see below).
Please note that 2 additional 4.7Kohms pull up resistors (+5V) are needed on SCL & SDA.
the +5V and GND wire can be connected on the programming connector (see below) :

If you want to build the I2C board yourself, here is the schematic:

Optional Add-on : The "Select"/middle button

An additional button can be connected at the JA jumper position.
Needed if you want to browse the USB stick files images with the LCD and the button (Normal mode).
EDIT : Now optional since the firmware v3.0.21.1a

Optional Add-on : Buzzer sound output

You can connect a piezo or a magnetic buzzer to the JB jumper position.
A transistor is needed for the magnetic version.
The sound output can be disabled or enabled into the selector settings.
(Note : Please remove these old sound mod using directly the floppy step signal, they are producing reliability problems...)

Optional Add-on : Rotary switch

You can connect a Rotary switch to the J7 connector (Same connector used for the screens connection).

"Direction / Dir" -> J7 pin 1. (near the "JK" marking on the PCB)
"Clock / Ck" -> J7 pin 2.

- "Dir" & "Ck" position on J7 :

Code: Select all

                           _____|
                          |     |
                          | USB |
                          |_____|
    Dir OO Ck___________________|
    SDA OO|SCL
    GND OO|VCC3V3
        J7|
          |
__________|
If your rotary switch have also a push-button, you can connect it as the select button to the "JA" jumper position :

Troubleshooting

Gotek drive with 3 digits 7 segments display:

:arrow: This doesn't work : The display doesn't work at all

Check that you have removed the BOOT0 strap after the bootloader programming.

:arrow: This doesn't work : I only see "LDR" on the display

You still have to finish the flash process : copy the latest firmware UPD file present into the firmware archive and insert the usb stick.

:arrow: This doesn't work : I see "NOR" on the display when inserting the USB stick

The emulator is in "NORmal mode".

Since you don't have any OLED or LCD screen, you need to use the indexed mode or the "autoboot" mode if you have an Amiga/Atari ST/CPC.
In this mode you must use the indexed config file and name the files images DSKA0000.XXX, DSKA0001.XXX, DSKA0002.XXX (replace XXX by the original file extension.) See the usage page for more details.

:arrow: This doesn't work : The floppy image appears to be loaded by the emulator, but the machine can't read the disk.
The Gotek green LED is permanently lit (no flashing)


The floppy ribbon is probably connected to the wrong way. Try to reconnect it to the other way.

Explanation : A wrongly connected floppy ribbon force the drive selection by short-circuiting the floppy signals to the ground, and make the selection LED always lit. Of course the machine can't communicate with the emulator in such situation.
Be aware that with some machines the floppy ribbon coloured wire is NOT the pin 1 !
