IDE stopped working

Development Tools Uploading
1

IDE does not work on COM1, I have CH340 installed. I have the latest IDE version.

Hi @mikemarcu. Please perform this experiment to verify that COM1 is your Arduino board:

  1. Disconnect the USB cable of the Arduino board from your computer.
  2. Select Tools > Port from the Arduino IDE menus.
  3. Take note of the ports (if any) listed in the menu.
  4. Close the Tools menu.
    :red_exclamation_mark: The ports list is only updated when the Tools menu is re-opened, so this step is essential.
  5. Connect the Arduino board to your computer with a USB cable.
  6. Select Tools > Port from the Arduino IDE menus. - If a new port is listed in the menu, that is the port of your Arduino board.

If you saw a new port appear at the last step, select that port from the Tools > Port menu and try uploading again.

If this doesn't solve the problem, please reply here on this forum topic with the answers to the following questions:

  • While following those instructions, did you see a port in the Tools > Port menu at step (6) that was not present at step (3)?
  • If you did see a new port, was the upload successful after you selected that port?

I changed the USB cable that worked yesterday evening, (you buy China, you China quality) and now it seems to work. And YES, I see more COM ports, I'll keep you posted. Thanks,
