Hi,
I'm working on a new project that will have a simple bootloader that will look for a connected SPI flash chip and load the program stored into the internal flash.
The device also has a display that needs to be initialised, so I thought the bootloader could handle this task as well at power-on. It then occurred to me that this would mean the bootloader would have code to deal with writing to the display.
Is it possible for the 'main' program to jump into subroutines located in the bootloader section and return back to the main program again?
Thanks
