Flash Loader Tool 7.5.0 — Structured Tutorial

Typical Workflow

1. Hardware Setup

   • Connect STM32’s USART1 (PA9/PA10 on most devices) to an RS232 transceiver or USB-UART adapter.
   • Set BOOT0 pin = VDD (high), BOOT1 = GND (low).
   • Reset the device.

2. Software Configuration

   • Launch Flash Loader Demonstrator.exe (v7.5.0).
   • Select COM port, baud rate (start with 9600 or 115200).
   • Click Next – the tool sends an auto-baud synchronization byte.
   • If successful, device information (PID, version, flash size) appears.

3. Flashing

   • Choose target sectors/pages (or “Erase necessary pages”).
   • Load .hex or .bin file.
   • Enable “Verify after download” (recommended).
   • Click Next to program.

4. Finalize

   • Set BOOT0 back to GND and reset – the user code runs.

Step 6: Execute the Code

• Set BOOT0 back to 0 (GND).
• Reset the board.
• Your application should run.

Introduction

Flash Loader Tool 7.5.0 is a utility software developed by STMicroelectronics (ST) for programming the internal flash memory of STM32 microcontrollers via the built-in system bootloader. This version, while older than the newer STM32CubeProgrammer, remains widely used in legacy production lines, offline environments, and by engineers who prefer its simplicity for UART/USART-based programming. flash loader tool 7.5.0
