Build options changed, rebuilding all

option enabled in File -> Preferences.

If the port is right and problem persist, try lowering the speed a bit as mentioned in the document.

Hope this helps.

 

It works. Thank you!

 

I had a older Serial driver in my MacBook Pro machine. i updated it and now it works fine
