Arduino Ethernet persistent sync error

[uberhund]

Though it communicates with the IDE serial terminal emulator perfectly, my Arduino Ethernet card refuses to be programmed across my FTDI cable, even when using IDE v1.0. Instead, I receive the familiar error shown below

Code: Select all

avrdude: stk500_getsync(): not in sync: resp=0x00


The FTDI cable I'm using uploads sketches fine with other FTDI Arduino types (Menta, e.g.). However, the Arduino Ethernet card has never successfully accepted a sketch regardless which Windows7 IDE v1.0 system I try.

Is it time to trade in this Arduino Ethernet card for a replacement?

Check your board type selection. The Arduino Ethernet is a type unto its own.
Post the verbose output from an upload attempt (File->Preferences "Show Verbose Output" for upload.)

Thanks for the suggestion. Here's the verbose output:

avrdude done.  Thank you.

Board selection was correct (Arduino Ethernet).

Thanks again for your thoughts,

The board does serial communication via the same FTDI cable? Does the board show signs of resetting when you start a download? You might try pressing the reset button at about the time the upload starts (may take a few tries to hit the timing right).

What OS are you using? Mac & Linux may require some additional tricks to get the auto-reset working.

Yes, successful serial communication is over the same cable that invokes the sync error.

Wow. This eventually worked. I'm getting an upload every three attempts or so, on average. Anyone know if later versions of the Arduino Ethernet will behave less petulantly? These sketches take so long to compile, that three or more upload failures per debugging/testing cycle extends the development time into something approaching impractical.

What OS are you using?

Windows7 (32- and 64- bit, depending where I physically happen to be).

Anyway, many thanks for getting me moving forward again with this work around.
