Topic: Sync problem with 019 but not with 018 (Read 2651 times) previous topic - next topic


I can flash my programs consistently with the 018 IDE but when I try 019 I have to try the upload two and sometimes three times to not get the sync error. Anyone else experience this or have some advice?

I'm using windows vista, Arduino pro 5v., Sparkfun FTDI adapter.



I occasionally got this with 0018, not had it yet with 0019

not sure as to the route cause, maybe it depends on what sketches you are running. Have they been the same ones for 0018 and 0019?



Hi Mowcius, thanks for the reply.

Yes, exact same program. If 019 doesn't load my sketch, I can immediately start 018 and it will upload without a hitch!

It's not a huge deal having to try 2-3 times with 019, but it's really bugging me! Ha!


yeah, just another bug...

At least it works (in a fashion)  ;)

Post your PATH environment variable.


Here it is:

C:\WinAVR-20100110\bin;C:\WinAVR-20100110\utils\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Common Files\Roxio Shared\DLLShared\;C:\Program Files\Common Files\Roxio Shared\10.0\DLLShared\;C:\Program Files\QuickTime\QTSystem\

Is there a copy of AVRDUDE.EXE in either of these locations...



Yes, I have it in this one:

Remove those two entries from your PATH and test.

Please let us know if it does or does not work.


Thanks Coding. I removed the entries but it didn't seem to help. In fact, it broke 018 so I added it back in.

The AVRDUDE that came with Arduino 0019 is...

avrdude -v

What version is in the "C:\WinAVR-20100110\bin" directory?

Are there any other versions on your computer?


Ok, I'll try that. I'm out of town until Friday, but I'll try that when I return.


I somehow had AVRDUDE 5.1 in the folder. I downloaded and replace it with 5.4 and now it seems to be working! I did quite a few test uploads and so far, so good.

That was great troubleshooting. Thanks, Coding.

You are welcome.  You know what they say, "Even a blind hunter gets a racoon now and then."

Wait.  No one says that.  But you get the point.
