I would like to do a secure boot on B-L475E-IOT01A: development board. CAn any one share me a tutorial or steps on doing a secure boot on B-L475E-IOT01A: I am using Azure RTOS.

Hello @GirishKumar​ ;

I'd highly recommend you the X-CUBE-SBSFU' (Secure Boot and Secure Firmware Update solution).

 It allows the update of the STM32 microcontroller built-in program in a secure way.

The software comes with an SBSFU example implementation running on B-L475E-IOT01A.

STM32CubeExpansion_SBSFU_V2.6.1\Drivers\BSP\B-L475E-IOT01\

A documentation is available:

•  UM2262 getting started with the X-CUBE-SBSFU
• AN5056 Integration guide for the X-CUBE-SBSFU
• AN5447

Thank you very much Imen for your response.

I will read through it and get back to you

Another question. While doing a secure boot is there any chance I may end up damaging the board ? I mean bricked - beyond recovery ?
