This is probably something trivial but I just decided to switch to IDE 2.x (2.3.2) and after successfully compiling an existing sketch for Arduino micro, uploading stops at the "configure and upload" dialog box.
Hi @Watcher. Check to make sure you have the serial port of the Micro selected from Arduino IDE's Tools > Port menu. If you didn't have the right port selected, select the correct port and then try uploading again.
I'm going to ask you to provide the full verbose output from an upload attempt.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open.
Check the box next to "Show verbose output during: ☐ compile" in the "Preferences" dialog.
Check the box next to Show verbose output during: ☐ upload.
Click the "OK" button.
The "Preferences" dialog will close.
Attempt an upload, as you did before.
Wait for the "Configure and Upload" dialog to appear.
Click the "CANCEL" button in the dialog.
The dialog will close.
Right click on the black "Output" panel at the bottom of the Arduino IDE window.
A context menu will open.
Select Copy All from the menu.
Open a forum reply here by clicking the "Reply" button.
Click the <CODE/> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Thanks for the update! Even though it is not as satisfying as finding an explanation for the problem, I guess we can be happy enough that the problem is no longer occurring.
If it comes back later, let us know and we'll see if we are able to investigate further.
