Webvector for the first address load to the PC for out-of-chip RESET. To make this position-independent, each entry should be recalculated according to the image’s run-time load address. This step is done by the loader. The loader also assigns an offset to the NVIC vector table base address (SCB_VTOR) before starting the application.
