Topic: Trouble with a Sanguino (Read 1 time) previous topic - next topic


I'm having some trouble operating my sanguino. I've folowed all the steps on their website to a T, but to no avail.

My error messages arise when I upload to the board.
avrdude: stk500_getsync(): not in sync: resp=0x30
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

Does anybody know what I can do to fix this?



I got this message when I picked the wrong COM port in the Arduino software.


By now, it's no longer giving me the message every time I upload. It allows me to upload after a reboot, but only the first time I upload. After I do it once, I need to reboot my system to upload again.


Have you tried disconnecting and reconnecting the sanguino instead of rebooting?


"Have you tried disconnecting and reconnecting the sanguino instead of rebooting?" Yes. Yes I have.

Anybody else having this same problem?


Now I'm getting the same problem with my arduino. Please help if you know anything.


Providing information about your computer/operating system would make it easier for people to help you.


Im running Windows XP on a laptop. I've got an Arduino Diecimilla and the Sanguino v1


Did you try all the relevant suggestions here: http://www.arduino.cc/en/Guide/Troubleshooting#toc2


I have found that the simplest solution to this situation is to compile the sketch, place the cursor on upload, press the reset button, press the enter key to start the upload, press the reset key again.  It has worked 100% of the time for me and I have tested it on 42K+ sketches.  There is a visual indicator that the sketch is uploading, the debug (red) LED will oscillate.


It is quite possible your ftdi chip is really causing the issue.  Here follow this tutorial http://ladyada.net/make/fuzebox/programprep.html scroll down until you see "Hacking the cable part 1"  this will show you how to configure your ftdi chip on your arduino and in your ftdi usb programming cable.
