Arduino Nano Connect to hidden COM port 4

Development Tools IDE 1.x
1

Dear community, I am using an Arduino Nano on windows 7. The only COM port on IDE that showed up was COM1 and usually my device work with COM4.

From administrator mode Device Manager I saw both COM3 and 4 (CH340) showed up and grey out. How should I activate them? Many thanks.

So after COM4 was set up at device manager, I reboot the computer and reconnect Arduino to flash code.
Still got error shown below:

avrdude done. Thank you.

Problem uploading to board.

I really appreciate your help!

Select Tools > Processor > ATmega328P (Old Bootloader) and then try uploading again.

Hi Brattain,

Thank you for the advice. However, the only two options I saw was ATmega328P and ATmega168.

Try this:

  • Tools > Board > Boards Manager
  • Wait for downloads to finish
  • Click on "Arduino AVR Boards by Arduino".
  • Click the "Update" button.
  • Wait for the update to finish.
  • Click the "Close" button.
  • Try uploading again.

Hi Brattain,

Thank you for the advice. If it still doesn't work, should I consider hardware issue on the broad?
