• (link to:) pjrc.com
  ----------------------------------

• This is the procedure (from the link above) that I followed to install Teensy board management on my Beelink mini computer
  that is currently running Arduino 2.2.3 via AppImage.
  ----------------------------------

• Install boards manager:
  • In Arduino IDE:
    Files --> Preferences --> Settings tab
    at the bottom, under "Additional boards manager URLs:"
    click icon to the far right (with double interlocking squares)
    dialogue box opens: "Enter additional URLs, one for each row"
  • I copied and pasted the line from the link above:
    "https://www.pjrc.com/teensy/package_teensy_index.json"
    click OK to close the settings dialogue,
    click OK to close the boards manager icon window
  • Back in Arduino IDE main screen,
    Tools --> boards --> Boards manager
    The boards manager will open in the left sidebar
    In top search filter bar, enter "Teensy"
    It should find and list "Teensy (for Arduino IDE 2.0.4 or later)"
    click Install
    1.59.0 was installed

  ----------------------------------

• Download and install udev rules:
  • Put this URL into your browser URL line:
    https://www.pjrc.com/teensy/00-teensy.rules
  • A text file will be displayed. This is the udev rules file.
    Select all and copy, then paste into a new text file.
    Save the new text file to your Desktop or wherever else you have file manager permissions.
    Save the text file as filename: 00-teensy.rules
  • Open a terminal.
    $ cd ... to Desktop (or wherever you put the teensy.rules file)
    $ sudo cp 00-teensy.rules /etc/udev/rules.d
    you may want to ls the rules.d folder to be sure the file is there.

  ----------------------------------

• done ...
  • It appears that with my IDE 2,3,2, I do not need to separately install the "loader" app.

    ...

    ...

    Proceeding on that assumption:

  • Here's what I tried:
    Open IDE 2.3.2 (AppImage)
    Open easiestBlink program into IDE
    Plug in Teensy. Confirm in-board blink program operates.
    Tools --> Board --> select Teensy 4.0
    Tools --> Port - none selected
    Tools --> USB Type: "Serial"
    Click Verify in IDE.
    Note loader will open (probably minimized to task bar)
    Pressed PB on Teensy. Red LED came on, stayed on, nothing else happened.
    Clicked upload in IDE.
    Upload error: read ECONNRESET

    not this time...

    Error:
    "Teensy should be selected from "teensy ports" rather than "Serial ports" in Arduino's Tools > Port menu
    No Teensy boards were found on any USB ports of your computer.
    Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.
    Failed uploading: uploading error: exit status 1"

    But "loader" window opened as well.
