Bootloader PC tool for loading firmware from PC
Introduction
The serial bootloader is a stand-alone package consisting of two parts: embedded
bootloader that should be loaded to the flash memory of a supported MCU and the PC
based application that sends data to the embedded bootloader over serial link.
The package contains all necessary sources for modifying and compiling the
embedded bootloader, including projects files for various development tool chains.
Chapter 1 Overview provides an overview of serial bootloader and package’s contents.
Chapter 2 gives brief starting instructions including including serial ports and fuse
settings. Following chapters cover more specific topics. Chapter 3 describes
embedded bootloader application. Finally, Chapter 4 gives instructions on how to
create an SREC image and program a device with it, using the Atmel Bootloader PC
tool.
