RA6M5 Mcuboot wrapped P384 support

Dave

Hi team!

I am trying out the MCUBoot on a the EK-RA6M5, it is going well so far, I have a couple of questions:

  1. I see that MCUBoot supports p384 signature types, is this possible in the FSP? (the only options I see are P256, RSA2048 and RSA3072)


  2. Is it possible to use a wrapped certificate to authenticate the images in protected mode? 

Warmest Regards,
Dave

    Hey Dave,

    As per the hardware manual, the MCU supports P384, but it's not supported by the FSP. While it is possible to use a wrapped certificate for image authentication in protected mode with MCUBoot, the current MCUBoot implementation for Renesas devices doesn't natively support certificate-based authentication. You'll need to implement custom features in the FSP-generated code to enable this functionality.
