Not IN Sync ERROR

Development Tools IDE 1.x
1

I recently started a basic robotics course at my school and we just started some basic programming. However anytime I try to upload my program I get this error message. Solutions on other forums that say to check the board selection and port selection have not helped because I already have the correct settings selected. I've also redownloaded and reinstalled multiple times with no change. Please help!

SNCC:

And still I believe the error is there :wink: Open up the Windows Device Manager. Can you spot the Arduino?

If not, is there any item with a ! in front?

In both cases, please post a screenshot of it.

The only Arduino in my Device Manager is under ports and it states that all my drivers are up to date

Alright, seems okay. Do you have anything connected to the Arduino? If yes, disconnect ALL (even if you think it's nothing) but the USB cable to the computer.

Even with everything (except USB) unplugged, I still encountered the same problem. Is it possibly a problem with the board itself? I will also post a video of the blinking that the board puts out when the error occurs. Thank you for all your help!

Then the only possible cause I know is no/corrupt bootloader on the chip... If you have another Arduino (or a programmer) you can try to reburn the bootloader.

To check the communication you can do the loopback test

Turns out that the board (new) is the issue. Borrowed an identical board from a classmate and everything ran fine. I'm hoping I can send the board back to get a replacement. Thank you again for all your help!

Then first try to re-burn the bootloader now you have a second working Arduino :wink:

Please try the loopback test and verify your serial connection actually works fine
