Board and port selected always shows with warning icon

[toogooda]

Describe the bug
Every board I select always shows with a warning icon next to it, even though upload works and so does output.

To Reproduce
Steps to reproduce the behavior:

1. Select any valid board and com port
2. See warning icon

Expected behavior
No idea as there is nothing to tell you what it is for, it shows a red 'x' when nothing is connected so I assume a green icon or nothing when a arduino is connected.

Screenshots

Desktop (please complete the following information):

• OS: Windows
• Version: 10

Additional context
I wasted time trying to work out what I had wrong because the warning icon indicated a potential issue.
Tried on multiple Arduino compatible devices.

Thanks for reporting, @toogooda. It's the expected behavior. You can see here how it works. In a nutshell: if the Arduino CLI cannot recognize your board, no fqbn is available via the board list command, you will see a warning.

This is the CLI's output when I have attached a MKR1000 and ESP8266 board. You can see the details for the ESP8266 is not available.

./arduino-cli board list --format json
[
  {
    "address": "/dev/cu.URT2",
    "protocol": "serial",
    "protocol_label": "Serial Port"
  },
  {
    "address": "/dev/cu.URT1",
    "protocol": "serial",
    "protocol_label": "Serial Port"
  },
  {
    "address": "/dev/cu.Bluetooth-Incoming-Port",
    "protocol": "serial",
    "protocol_label": "Serial Port"
  },
  {
    "address": "/dev/cu.usbserial-0001",
    "protocol": "serial",
    "protocol_label": "Serial Port (USB)"
  },
  {
    "address": "/dev/cu.usbmodem14401",
    "protocol": "serial",
    "protocol_label": "Serial Port (USB)",
    "boards": [
      {
        "name": "Arduino MKR1000",
        "FQBN": "arduino:samd:mkr1000",
        "VID": "0x2341",
        "PID": "0x804E"
      }
    ]
  }
]

I am closing as invalid. Let me know if you disagree, @toogooda. I am happy to discuss it further. Thanks!

Hi kittaakos,
Thanks for your explination. by far the majority of clones will use the CH340G/C which will not return a FQBN as the chip uses a default I believe. This will just be a nag or confusing(what have I done wrong?) to everyone who uses them. Is this feature more hinderance than help?
It is helpful displaying the selected board and port, and auto populating when you can but this permanent warning seems like a step to far.
I could do a hundred successful uploads and it will still be warning me.
Can I toggle it off?

@toogooda you are in the right.
A warning sign should be an indicator that something is wrong.

We'll look into it 👍🏼

Can there be a way to set my preferred serial port patterns? I only ever have ttyUSB* (rarely ttyACM*) and right now ttyUSB0 is waaaaaaaaayyyyyy down at the bottom, below a bunch of ttyS* devices.

Also, I have some devices that don't even have a usb-serial on them; I just plug in the nearest 4-pin serial cable to the UART header.

Unfortunately cleaning up your serial ports files is up to you.
we run a serial discovery which lists every serial device on the system so if you have 50 serial ports that's what you'll get

I too wasted time investigating this warning before I found this post.
I would like to propose a solution: An explanatory message pop up when the mouse is hovered over the warning icon.
