The STM32-SFI Flasher Commander is a command line interface (CLI) tool developed to support the Secure Firmware Installation (SFI) feature from STMicroelectronics. There is no additional license required to use it with Flasher Compact, Flasher PRO or Flasher PRO XL.
As part of the production process for SFI-enabled STM32 microcontrollers, the intellectual property (IP) owner sends encrypted firmware along with the corresponding decryption key to the facility responsible for programming the microcontrollers during production. The firmware decryption key is securely stored on a Hardware Security Module (HSM). Programming can take place at any production site, even external, such as a contract manufacturer or a distributor that offers mass programming of stocked devices for delivery.
At the programming facility, the STM32-SFI Flasher Commander interfaces with SEGGER's Flasher PRO, PRO XL, or Compact in-circuit programmers and transfers the encrypted firmware image and the matching firmware decryption key (also in encrypted form) to the target MCUs to be programmed.
- Supports Secure Firmware Installation (SFI) from STMicroelectronics
- Ensures secure transfer of firmware to the target
- Runs with Flasher PRO XL, PRO and Compact
The following hardware items are required to program:
- Smart card reader connected via USB to the host PC
- STM32HSM Smart card STM32HSM-V2
- Flasher PRO, Flasher PRO XL, or Flasher Compact
- STM32CubeProgrammer to set up a project

If the target device does not support ST’s SFI, SEGGER has got you covered with the sophisticated production programming system Flasher Secure.
Combined with the SEGGER's Target Encrypted Link Package (TELP), it enables hardware without security features to be programmed securely. Using TELP, any microcontroller can be programmed with an encrypted firmware or bootloader image.
