Make sure that the controller type is referenced corrctly in the makefile: MCU=atmega16 yes in the makefile, not in template.asm. The atmega-16 may need a few more lines in template.asm: 1. after the baud rate add the 5 ".equ ..." lines ; initial baud rate of terminal .equ BAUD = 115200 ; additional .equs for "old fashioned" mcu with usart, not usart0 .equ TXEN0 = TXEN .equ RXEN0 = RXEN .equ RXCIE0 = RXCIE .equ UCSZ00 = UCSZ0 .equ TXCIE0 = TXCIE 2. .include "drivers/usart.asm" -----------------------^^ remove the _0 here. This works for me on atmega-32.
