Serial Monitor window not connecting - Mac M1

I'm running IDE 2.02 on a Mac with the M1 chip. The Mac is running OSX Monterey 12.5.1

I have a Portenta H7 Lite connected to the Mac via the USB-C port on the H7. I am able to compile and upload codes succesfully to both the M4 and M7 cores of the Portenta H7.

The Serial Monitor sub-window in each of my IDE windows I have open is not able to connect to the Portenta H7 so I am not abe to see any serial output from println statements. The serial monitor tells me to select a board and port so it can connect, even though I already have the board and USB port selected in that window.

What's wrong? How do I connect the serial monitor to the board and core so I can see the serial output?

Thanks.

Hi @FerroMaker121. Thanks for your report. Would you mind providing a screenshot of the entire Arduino IDE window when Serial Monitor is in this state? This will allow me to be sure I completely understand the problem, and I also might be able to spot some subtle detail there that puts me on the right track in my investigation.

You can then add the screenshot to a reply here by doing any one of the following:

  • Press Ctrl+V to paste the screenshot from the clipboard.
  • Save the screenshot as an image and then drag and drop it into a forum reply.
  • Save the screenshot as an image, click the upload button (image) in the post composer toolbar, and then select the image file.

The screenshot shows the IDE windows for M4 and M7 codes. I'm now running IDE 2.03 on an M1 iMac. The Portenta H7 Lite is connected to the Mac via USB-C, and the two codes are running as expected. Uploading via USB is working. What I am trying to do is use println() to print debug messages on the Serial Monitor section of the IDE window. The monitor window says I'm not connected, or it provides a line to send a message on the port which is not useful for what I am doing. I may not be setting up the ports correctly. My understanding is that it is Serial port 0 that connects to the Serial Monitor, and that this port communicates by the USB-C port on the H7. That connection does not appear to be working. How many serial ports does the H7 Lite have, and can all of them go over USB, or just port 0?

I am also trying to use an I2C port to send data from the H7 to a 14-segment alphanumeric display (Sparkfun Qwiic) but so far I cannot get that to work either. My understanding is that I2C is also a type of serial port.

Thanks for your help.

Here's another screenshot with the IDE window for the code I'm running on the M7 core. This one displays a gold-colored bar saying the Serial Monitor is not connected. I'm not sure what this means. I have not been able to get println() to work with either code or window.

It appears that the proper board and port are selected, but I still get the message saying the Serial Monitor is not connected, and telling me to select a board and port.
