Couldn’t find a Board on the selected port. Check that you have the correct port selected. If it is correct, try pressing the board’s reset button after initiating the upload.

This report would have more information with
“Show verbose output during compilation”
option enabled in File → Preferences.

Your problem was NOT the same as the other one !

TOPIC SPLIT DO NOT HIJACK !

Could you take a few moments to READ THIS. It will help you get the best out of the forum.

Bob.

What happens in Windows device manager when you press and release the reset button on the Leonardo?

Before pressing the reset button, you should have a port called "Leonardo". After pressing and releasing the button, it should change to another port called something like "Leonardo boot loader".

If that doesn't happen, I think that you have to burn the boot loader via ICSP.

If it indeed changes, you can upload by pressing and releasing the reset button when the lines with PORTS {COM8, } / {COM8, } => {} start showing.

Your 'log' seems to be missing one crucial piece of info; there should be a line about resetting the Leonardo at 1200 baud before the com port lines. I doubt you did cut it out. Without an attempt to reset the Leonardo, it will indeed fail to find the boot loader port.

Why are you using an hourly build of a (to my knowledge upcoming version of the) IDE? Maybe it has a bug? Try IDE 1.8.10 instead.

To ballscrewbob: l read offen the sentence "Do not hijack". What is the meaning? Because I'm German, I have no idea. But it looks important.

Somebody starts a thread asking a question. Somebody else ask a question on the same thread, either related or not.

That is called hijacking.

If it's not related to the original question, it's just wrong. If related, it makes it more difficult to follow the thread; e.g. who is replying to which question.
