2.4 Toolchain

In order to build an application from the source code a toolchain is needed, which

includes the required tools like assembler, compiler, and linker. The code for this kit is

compatible with the AVR GNU and IAR™ AVR toolchains.

2.4.1 AVR GNU toolchain

The AVR GNU toolchain is a free toolchain that can be downloaded from the Atmel

webpage. It includes all necessary tools like a C/C++ compiler, assembler and linker,

which are necessary for the AVR application development. The toolchain integrates

with the Atmel AVR Studio 4 through the AVR GCC plug-in.

2.4.2 IAR AVR toolchain

The IAR AVR toolchain is a commercial toolchain which includes all necessary tools

like C/C++ compiler, assembler and linker which are needed for the AVR application

development. There is a 30 day evaluation version as well as a 4k (code size limited)

kick-start version available from their website.

2.5 Programmers and debuggers

Programmers and debuggers are needed when either the application should be

programmed without using the bootloader, or when debugging support is needed.

Several different tools are available that can be used directly with the Xplained kit; the

most common of these are described in the next chapters.

2.5.1 Atmel AVR Dragon

The AVR Dragon™ is a low-cost debug/programming tool that can be used for code

development with the Atmel MEGA-1284P Xplained kit.

2.5.2 Atmel AVR JTAGICE mkII

The AVR JTAGICE mkII is a mid-range debug/programming tool that can be used for

code development with the MEGA-1284P Xplained kit.

2.5.3 Atmel AVR ONE!

The AVR ONE! is a high-end debug/programming tool that can be used for code

development with the MEGA-1284P Xplained kit.
