I have an Arduino Nano clone and have been happily compiling and uploading sketches using 1.6.7 for quite a while. As I kept getting messages to upgrade I decided to do that and upgraded to 1.8.16. After this my sketches compile well but uploading fails. I then visited the website and installed 2.2.1 but the uploads still fail.
I should point out that with the IDE active and the USB cable unplugged the box below the menu bar says Arduino Nano with a feint font and when I plug my board in the font changes to bold. I deduce that some communication is possible.
Here is a screen shot of the verbose upload diagnostics:
...sorry, I should have added that if anyone has any advice I'd be very grateful.
Mike.
close any other program, may be reopen IDE, maybe restart PC.
Thank you kolaha for your prompt reply.
I tried that and the result was exactly the same.
is serial monitor open?
I should also say that I checked the device manager:
I notice that the service running was: CH341SER_A64
whereas the port's name is USB-SERIAL CH340 (COM3)
I searched for CH341SER_A64 using the process explorer and it couldn't find anything.
No it's not.
does COM3 disappear when you disconnect Nano ?
Yes, it does.
good, does arduino blink three times when you connect it to USB?
did you tried this option?

No, this is the sequence:
- The LED nearest to the Ax pins flashes
- The LED 2nd nearest the Ax pins comes on
- The LED 3rd nearest the Ax pins comes on (about 1 to 1.5 seconds later)
This produced this:
Sketch uses 4760 bytes (15%) of program storage space. Maximum is 30720 bytes.
Global variables use 96 bytes (4%) of dynamic memory, leaving 1952 bytes for local variables. Maximum is 2048 bytes.
