Firmware Flashing

This guide details the complete process of writing firmware to Flash in sftool-gui, covering device connection, firmware selection, and flashing execution.

Flashing Preparation

Before starting the flashing process, ensure the hardware is connected properly and software parameters are correctly configured:

1. Start the software: open the sftool-gui application.

2. Configure the chip: in the Chip Selection area, accurately choose your target chip model and memory type.

3. Set the interface: in the Interface Settings area, select the serial port and baud rate corresponding to your hardware connection.

4. Establish connection: click the Connect Device button. Wait for the status bar to indicate a successful connection (as shown below).

Selecting Firmware

sftool-gui supports various firmware formats and provides intelligent address parsing. Refer to the following instructions according to your file type:

1. Auto-configuration Mode (Recommended)

Use the following formats to automatically handle multi-file loading and address allocation—most convenient:

• sftool_param.json configuration file

  Note: The system will automatically populate Bootloader, Ftab, Main, and other binary files and their corresponding addresses based on the JSON configuration.

• .zip / .rar / .7z archives

  Note: Ensure the archive contains sftool_param.json. After importing, the software will automatically extract it to a temporary directory (cleaned on exit) and parse the configuration.

2. Automatic Address Detection

• .hex / .elf / .axf files

  Note: The software will automatically parse and fill in the flashing addresses.

3. Manual Address Configuration

• .bin raw binary files

  Note: After importing the file, you must manually enter the flashing address in the address field.

Executing Flash

1. Start writing: after confirming files and configuration are correct, click the Start Flash button.

   Tip: During flashing, the row for the file currently being written will be highlighted.

2. Completion and Reset:

When the system log box displays Flash completed!, the operation is finished. You can then disconnect and reboot the device to apply the firmware.
