Application Properties


Properties of the application that can be accessed by the bootloader.

Applications must contain an ApplicationProperties_t struct declaring the application version and capabilities, and so on. The metadata contained in this struct will be extracted from the application by the Simplicity Commander tool and placed in the EBL upgrade file. If such a struct is not present in the application image, it will be added to the EBL file by the Simplicity Commander.

The struct is also used to declare whether the application image is signed and what type of signature is used. If no ApplicationProperties_t struct is present, the bootloader will assume that the application image is signed using APPLICATION_SIGNATURE_ECDSA_P256.

For the bootloader to easily locate the ApplicationProperties_t struct, if not already done by the linker, Simplicity Commander will modify word 13 of the application to insert a pointer to the ApplicationProperties_t struct.
