hi Kindly let me know how the branch instruction is loaded in reset vector address (0xffff_fffc), but i have mapped my boot flash from 0xE000_0000 to EFFF_FFFF in LAW.
When the chip starts execution, the boot vector is mapped at 0xfffffffc. The boot code then changes the flash mapping (with an interim state where it's mapped repeatedly throughout the address space) before it runs any code that depends on the link address.
