AVR Linker - Manual Link, Bare Metal and Mixed Source Code
This article discusses how to write assembly code using the GNU avr-as assembler for AVR microprocessor and how to link the object files into AVR executables. Furthermore, it shows how to write a bare metal C program with manual link, and how to write a program with mixed C and assembly code for AVR.
