Hi, if I set PS_ENCRYPTION=OFF
set(PS_ENCRYPTION OFF CACHE BOOL "Enable encryption for Protected Storage partition")
I see this compile error:

I think the correct fix is to add the following highlighted code to ps_object_defs.h. Patch is attached. /*! * \struct ps_object_t * * \brief The object to be written to the file system below. Made up of the * object header and the object data. */ struct ps_object_t { struct ps_obj_header_t header; /*!< Object header */ uint8_t data[PS_MAX_OBJECT_DATA_SIZE]; /*!< Object data */ #ifdef PS_ENCRYPTION uint8_t tag_iv[PS_TAG_IV_LEN_MAX]; #endif };
