This error keeps repeating then it disappears for a while and comes back. I tested on another computer and they don't have that issue. I did updates all of that. Any other tips ?
this didnt work for me, in the end had to connect B1 to Ground, hit the button, disconnect the ground. it puts the nano in bootloader mode with the LED glowing dimmed red color. THen usee ACM0 port (using ubuntu here)
I tried this and got this error after it tried to upload: Port monitor error: command 'open' failed: Serial port not found. Could not connect to COM6 serial port. Any ideas?
I had the same problem but on my giga R1 WIFI. Before I upload a sketch I need to always press my reset button twice, it will turn green. Hit upload and my sketch gets transferred.
