Ultra-Secure CLI Platform for Trustworthy 32-bit MCU Programming

01 January 2024

SEGGER’s STM32-SFI Flasher Commander is a convenient, free-of-charge command line interface (CLI) tool that offers support for the secure firmware installation (SFI) functionality that STMicroelectronics’ STM32 microcontroller units possess.

As part of the production process of hardware using SFI-enabled MCUs, the IP owner sends encrypted firmware along with the matching firmware decryption key (which is securely stored on a hardware security module). The encrypted firmware image and the matching firmware decryption key are then transferred to the target MCUs for programming to be carried out. This secure platform interfaces with SEGGER's Flasher PRO, Flasher PRO XL and Flasher Compact programmer solutions 

“As an active member of the ST Partner Program, we are happy to contribute reliable production tools for our mutual customers that fully embrace the specific production process of SFI-enabled STM32 microcontrollers,“ states Dirk Akemann, SEGGER’s Marketing Manager. “Our aim is to always ensure that customers, STMicroelectronics’ and ours, have the safest and most secure programming experience possible.”
