If you have any of those like that in your code (group of three !!!), that has been known to stop a code upload.

That issue is supposed to have been addressed in latest version of the mega2560 bootloader.

The problem he is having is that the version of avrdude he using (5.10) doesn't understand what the "wiring" protocol is.

I wonder why mine works? I'm using a Mega with v1.0.2.

Test the bootloader.

void setup() {
  Serial.begin(9600);
  Serial.println("It works!!!");
}

void loop() {
}

Can you upload that code?

When you upload a sketch via isp then it will overwrite the bootloader. You probably have no bootloader on the mega 2560. You will need to put back the bootloader.

Thanks all of you.
I replace the bootloader on secont chip 2560 via isp. Now it is ok. There was:
