Error when uploading sketch

[dawiinci]

I always get this message when I want to upload a sketch after I already have uploaded one. I have to unplug the Z-UNO in order to upload. I'm on the latest release. Is this a bug?

I have seen something similar, but I cannot remember what caused it. Long shot: do you use debugging via serial over usb? I have been using debugging over seria uartl instead of usb for the last few months, and I think that might have solved it.

Select the correct port.

The port should be correct because it works the first time and after reconnecting. However I will check next time to be sure.

I'm not using debugging functions, but thanks for the hint.

I confirm the port is correct. I uploaded the sketch once and after it close the port I uploaded it again >> Error.

Now it doesn't work until I unplug it once.
