Avrdude: ser_open(): can't open device "\\.\COM7"

Using Arduino Avrdude, stk500, Bootloader issues
1

I started doing a project that is a FreeDeck, but since I started trying to send the code to the Arduino Micro Pro it started giving errors, like this:

avrdude: ser_open(): can't open device "\.\COM7": O sistema n�o conseguiu localizar o ficheiro especificado.

Failed uploading: uploading error: exit status 1

and I also have this problem:

connecting to programmer: .
Found programmer: Id = "CATERIN"; type = S
Software Version = 1.0; No Hardware Version given.
Programmer supports auto addr increment.
Programmer supports buffered memory access with buffersize=128 bytes.

Programmer supports the following devices:
Device code: 0x44

If anyone could help with this error I would be grateful.

Is your Pro Micro still recognised by your operating system?

Do you have other Arduinos (Uno, Nano, Mega) or a serial-to-usb converter? If yes, you can try the following

  1. Connect a reset button between the reset pin of the Pro Micro and GND.
  2. Connect the other Arduino; keep the Pro Micro connected as well.
  3. Select the port of the other Arduino; keep the board as Pro Micro.
  4. Start an upload.
  5. Double tap the reset button when the IDE reports the memory usage.

Although it's displayed in red, it's not an error.
