The ST10 Flasher Tool is a software utility used to program the internal and external flash memory of STMicroelectronics ST10 series microcontrollers. It is widely used in automotive diagnostics to read and write ECU (Electronic Control Unit) firmware via a serial interface. Download Options
Official STMicroelectronics Software: The most reliable version is the STSW-ST10004 package from the STMicroelectronics website.
I/O Terminal Flasher: Owners of I/O Terminal hardware can download a dedicated ST10 boot flasher from ioterminal.com.
Third-Party Repositories: Older versions (like v2.4b) are often hosted on niche automotive forums such as Automoto Firmware. Key Features STSW-ST10004 | Product - STMicroelectronics
The ST10 Flasher Tool is a specialized utility designed to read, write, and erase internal and external flash memory for the STMicroelectronics ST10 family of 16-bit microcontrollers. Widely used in automotive and industrial sectors, it is a critical resource for technicians working with legacy electronic control units (ECUs).

The tool streamlines firmware updates and maintenance through the following functions:
Automatic Target Detection: Automatically identifies connected devices and CPU frequency ( Fcpucap F sub c p u end-sub ) to ensure compatible communication.
Comprehensive Memory Operations: Supports erasing memory by bank or block, loading hex files, and programming internal or external flash (e.g., M29F400).
Verification and Integrity: Includes built-in checks to compare embedded flash content against local files and verify programming success. The ST10 Flasher Tool is a software utility
Data Dumping: Allows users to dump flash memory to a file or directly to the screen for analysis.
Bootstrap Loader (BSL) Support: Operates using the standard bootstrap mode, allowing code execution from RAM for initial programming. How to Download and Install
While legacy versions exist, the official tool is often provided as part of technical support packages or specific hardware bundles. STSW-ST10004 | Product - STMicroelectronics

| Programmer | Protocol | Speed | Cost | |------------|----------|-------|------| | FTDI FT232RL (USB-to-TTL) | UART/BSL | Up to 115200 baud | ~$5 | | ST-Link/V2 (with adapter) | SWD/JTAG | High | ~$10 | | Original ST10 Dev Kit | Onboard BSL | Standard | Expensive |
Most common setup: FTDI adapter connected to ST10 pins:
TX on FTDI → RXD0 on ST10 (P2.12)RX on FTDI → TXD0 on ST10 (P2.10)GND → GNDRST and PORT0 pins to enter BSL mode.
