    PSoC 6 Bootloadable signature

    AnCi_2234676

      Hi,

       

      I want to generate a bootloadable file for my application and I was wondering if the signature (-S option of cymcuelftool.exe) is mandatory or optional?

      Also, if signed, where is the signature validation done / should be done?

       

      Thanks

          The signature is mandatory.

          elftool does add signature for application image only if add e.g. below line in main_cm4.c:

           

          CY_SECTION(".cy_app_signature") __USED static const uint32_t

          cy_bootload_appSignature[1];

           

          The signature should be validated during bootloading process. For more details of generating a bootloadable project, please refer to chapter 4.3 of AN213924.
