I am working on K22FN512VVL12 chip. We are planning to load application image to external flash memory. Now we want to update internal flash memory using bootloader.
Can we add this feature in a bootloader? Do we have any drivers available to access external flash data (Over SPI)?
On similar lines, do we have a feature of adding scripts (set of commands) to the default bootloader. if yes, how do we do that?
