Crossroads... sent you a mail but not received a reply.. looking for the cost of a bare board and a bootloader programmed 1284 posted to the UK.  Can you advise please

When did you send it?  I don't think it arrived, I've been watching for one. Or I missed in the daily flood of forum e-mails.

Anyway, $5 for the board, $8.14 for the 1284Pchip, no charge for bootloading, $5 for shipping in padded envelope.
So $18.50, paypal to cardinalflyer at comcast dot net

You will be building up for 16 MHz operation with a crystal, yes?

Robert,

Fantastic service - and whilst I wait for a few of the other components to arrive I've breadborded the 1284p as per this schematic



having downloaded the files from the site http://maniacbug.wordpress.com/2011/11/27/arduino-on-atmega1284p-4/  I can select the board in the drop down list, however when I come to upload the blink example I get the attached error.

I've tried swapping the TX / DX leads - no affect, different baud rates - no affect - on my FTDI board I get what seems to be a good comms as both TX and RX leds pulse, and shorting these wires results in an echo on the serial monitor, so the FTDI is working fine.

Anyone have any suggestions.  I thought the transition from PIC to AVR / Ardunio was going to be a smooth one !

Can't see the schematic, try again?

Do have DTR connected as well?  If not, you'll need to press Reset after the "Binary sketch size" message comes up.
