I have a bootloader and application firmware created using SEGGER Embedded Studio, but with the current flash size limitations, there is no room for adding new features to the application firmware. Is there a way to place functions used by both the bootloader and application firmware in a shared section, allowing both to reference these functions and reduce total flash usage?

Additionally, is there a method to import the bootloader’s symbol table into the application firmware so that functions defined in both the bootloader and application occupy memory only in the bootloader’s flash area?
