[SOLVED] no error message in compile but sketch is reseting

Projects Programming

I have modified the Ethernet web server example to learn more about processing POST data.

The compile completes with no errors and I am able to upload the sketch.

In Serial Monitor I see the server IP which is displayed by setup( ) is being repeated.

How do I debug what is causing this?

I have not opened a web browser to the Arduino web server.
The code is uploaded and that is it.
Nothing else.

Please let me know what else you need to see.

The code. In code tags, please. (Use the full editor and look for the button that looks like </> )

It's flash problem.

avrdude: 12178 bytes of flash written; sketch runs
avrdude: 12200 bytes of flash written; sketch runs
avrdude: 12204 bytes of flash written; sketch runs

avrdude: 12206 bytes of flash written; sketch malfunctions
avrdude: 12212 bytes of flash written; sketch malfunctions
avrdude: 12258 bytes of flash written; sketch malfunctions

I am going in an commenting out Serial.println("1234567890"); to change sketch size.

Remember that those strings are copied into RAM so I suspect you are running out of RAM, not FLASH. For string constants in a .print() or .println() use the F() macro:

 Serial.println(F("1234567890"));

That will keep those string constants from being copied to RAM.

Yeah, but with the Ethernet web server example nothing is happening unless a client connects.
I have not connected a client aka web browser yet.

So this is a sketch that is sitting there doing nothing.
I have just uploaded it.

I'll play with it some more and see what is happening.

That was it!.

Thank you!
