IDE 2.0 lost all com ports

dfeng · February 18, 2022, 8:25am

Hey everybody,
I completely new to Arduino and I have a problem that I cannot find a suitable answer for.

I recently started experimenting with an MKRZERO and IDE 2.0 on Win10 Professional.
First everything was fine, until I bricked the board by stupid code.
I found out how to start the bootloader (double-press) but the IDE would not recognize the board.

After hours I tried the old IDE, the board was found right away and I could upload a new sketch.

But still, IDE 2.0 does not recognize my board.
It does not even show any ports in the selection screen (show all ports is checked).
Since then I uninstalled both IDEs reinstalled, tried nightly builds, deleted the config manually, changed the com port of the board.

Now I´m running out of ideas.
I can use the old IDE but I´d really rather use the new one.

Does anyone have any ideas how to reset IDE 2.0 and convince it to look for available ports?

Thanks a lot
Daniel

Hi @dfeng. Thanks for your interest in the Arduino IDE 2.0.0 release candidate.

I would like to gather some additional information that might assist in the investigation. The first thing I need to know is:
Which operating system are you using?

dfeng · February 18, 2022, 9:30am

Oh, damn, forgot the most basic information, sorry.

I´m using Windows 10 Professional.

No worries. You might argue that it is obvious from the mention of the "com port", but I try to avoid making any assumptions since they can sometimes lead to unnecessary confusion.

I'm now going to ask you to provide the output you get from starting the Arduino IDE from the command line.

Please do this:

Start File Explorer (AKA "Windows Explorer").
Open the Arduino IDE installation folder
(usually C:\Program Files\Arduino IDE or C:\Users\<user name>\AppData\Local\Programs\Arduino IDE).
In the folder listing of the Arduino IDE installation folder, hold the Shift key while clicking the right hand button on the mouse.
From the context menu, click "Open PowerShell window here".
PowerShell will now open with the current directory set to the Arduino IDE installation folder.
Type & ".\Arduino IDE".
Press the Enter key.
Debug output should now be printed to the PowerShell window as the Arduino IDE starts (or fails to start).
Wait for the Arduino IDE to finish starting.
Switch back to the PowerShell window if the Arduino IDE window took the focus.
Right click on the title bar of the PowerShell window.
This will open a context menu.
Select Edit > Select All from the context menu.
This will select all the text in the PowerShell window.
Press Ctrl+C.
This will copy the contents of the PowerShell window to the clipboard.
Open a forum reply here by clicking the Reply button.
Click the </> icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
Press Ctrl+V.
This will paste the output into the code block.
Move the cursor outside of the code block markup before you add any additional text to your reply.
Click the Reply button to post the output.

Please let me know if you have any questions or problems while following those instructions.

I have a meeting starting right now, but I'll try to find more information about this later today.

If it helps, both directories contain a "license.txt" only.

Good news!
Your hint was enough to set me on the right track...

I found, that none of the directories...

mdns-discovery
serial-discovery
serial-monitor
...contained any executables.

But I found the correct packages under "\AppData\Local\Arduino15\staging\packages".
Once I copied the correct executables into those directories everything worked fine again.

I cannot reproduce, how those files were deleted or why they were not reinstalled, when I reinstalled the IDE.
But anyway, my problem is solved.

Thanks!

Great work on finding the solution! I'm glad it is working now.

I have a suspicion that your antivirus software might have interfered with the installation of these tools, which is done automatically when you start the Arduino IDE.

I found that, even though installation of missing tools is handled automatically, if there is an incomplete installation, then the IDE is not able to recover from that because it considers the tool to be installed if the folder is present.

I submitted a report about it to the Arduino developers:

github.com/arduino/arduino-cli

Recover from interrupted discovery/monitor installation

type: enhancement topic: code

### Describe the request Reinstall pluggable discovery and monitor tools of t…he `builtin` package if the tool executable is not found. ### Describe the current behavior Arduino CLI automatically installs [pluggable discovery](https://arduino.github.io/arduino-cli/dev/pluggable-discovery-specification/) and [pluggable monitor](https://arduino.github.io/arduino-cli/dev/pluggable-monitor-specification/) tools of the `builtin` package when missing or updatable. These tools allow Arduino CLI to find the "ports" used for communication with Arduino boards. It can happen that the installation is interrupted while in progress. 🙁 If a problem during the installation results in the creation of the tool's release installation folder without the tool executable, Arduino CLI can no longer do discovery. It will not automatically recover from this condition and the user must manually delete the incomplete installation in order to restore Arduino CLI to functionality. #### To reproduce ``` $ ./arduino-cli version arduino-cli Version: nightly-20220218 Commit: dd48868 Date: 2022-02-18T01:31:17Z $ rm ~/.arduino15/packages/builtin/tools/serial-discovery/1.3.1/* $ ./arduino-cli board list Error detecting boards: Error starting board discoveries: [discovery builtin:serial-discovery process not started: fork/exec /home/per/.arduino15/packages/builtin/tools/serial-discovery/1.3.1/serial-discovery: no such file or directory] No boards found. ``` ### Arduino CLI version nightly-20220218 ### Operating system Windows, Linux ### Operating system version Windows 10, Ubuntu 20.04 ## Additional context Originally reported at https://forum.arduino.cc/t/ide-2-0-lost-all-com-ports/960650 --- This situation is more problematic for Arduino IDE users, since the error message about the missing tool is not visible to them and they only notice the symptom of the IDE not seeing their ports. --- It might seem unlikely for this interrupted installation to occur under real world conditions, but the equivalent issue with Boards Manager producing incomplete tools installations has been reported by users periodically ever since the introduction of Boards Manager, at sufficient volume for Arduino Support to consider it worth a Help Center article: https://support.arduino.cc/hc/en-us/articles/360018444739-Error-file-does-not-exist-no-such-file-or-directory-system-cannot-find-the-file-specified

Hey @dfeng, could you delete the folder C:\Users\dfeng\AppData\Local\Arduino15\packages\builtin\tools\ and provide the Arduino IDE output again?

It's interesting to know why the installation failed but not the download.

Thanks in advance.
