Here lies probably the root cause: try including the usart_0.asm
file instead.
The following template.asm snippet did work out of the (trunk-) box
(note the additional 0 digits almost everywhere)
-----------
...
; initial baud rate of terminal
.equ BAUD = 9600
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)
.if WANT_ISR_RX == 1
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)| (1<<RXCIE0)
.else
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)
.endif
; 8N1 is commonly used
.equ USART_C_VALUE = (3<<UCSZ00)
.include "drivers/usart_0.asm"
..........
-----------------
template.hex:
[echo] Producing Hexfiles for atmega1284p
BUILD SUCCESSFUL
Total time: 4 seconds
-------------
Without that _0 the wrong usart drivers gets included (dont blame
me for that).
