Have you actually checked the fuses? Read them out with avrdude then run them through http://www.engbedded.com/fusecalc/ Also, the '644A has 2 baud registers UBRRL & UBRRH for each UART according to http://www.atmel.com/dyn/resources/prod_documents/8272S.pdf So I wonder if you are passing the right -mmcu arg? -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
