IDE 2.2.1: the Upload operation frozen in updating step if serial line is not connected.
The updating popup shows a progress bar, but I can't stop the operation.

The only way I found to exit from this situation is closing the IDE.

In this case I can edit the source code, I can verify the code but I can't select the upload operation, the upload button has orange background.

This will happen if you have while not serial loop in your code.
Remove it and replace it with a two second delay.

Exactly which serial line are you referring to ? Is it the USB connection to the PC or something else ?

What else is connected to the board and which Arduino are you using ?

Sorry,
Before of all, thank you very much for your help.
I think I don’t be fully clear, my fail, my English is really poor.

I don’t believe the issue is in my code, at least I hope :wink:

Ok I try to describe the situation

First case:

  • The computer is connect to Arduino Mega 2560
  • I select the Upload button
  • In this case, the upload always works well and finishes the operation

Second case:

  • The computer is not connect to Arduino Mega 2560
  • I select the Upload button
  • In this case, the Upload starts, it obviously it can’t finish the operation
  • The IDE shows the popup “Uploading….” and the upload button seems disabled ( orange background)
  • When I connect the Mega 2560 to my computer I can’t select Upload button
  • In this case, the only way I found is close the Arduino IDE 2.2.1 and restart it

It seems the IDE 2.2.1 has not a timeout for Upload operation.

If it is not clear, ask me further information, as I written, my English is poor :frowning:

Thank to all very much

Thank you for the clarification and don't apologise for your English, it is vastly better than my Italian
