I am using STM32L452RE for an application.
I want to implement firmware signing feature on the board so only authenticated firmware is allowed by bootloader to flash on the board.
Can i conclude that mbedtls library is popular, but it cannot be used on the board since there is no hardware accelerator?
I wonder that shouldn't be the case.
However, I saw this example library where data signing is implemented. I feel something can be done on similar lines. Please guide on how to implement this.
