Error when trying to debug Arduino M0 Pro

[rvdende]

Running 1.16 VSCode on Ubuntu Linux, installed the Arduino extension, I can upload code to the board and get data over the serial monitor just fine through VSCode.
Problem is if I set break points and Press F5, no matter what I do I get an error dropdown at the top of the screen: "[Error] Cannot read property 'apply' of undefined"

Any idea what I'm missing?

@fluentart Could you provide a snapshot for this issue with the console output?

[rvdende]

When you say snapshot what do you mean? My project folder or a screenshot?
I'll provide as much info as possible:

Please
1 . set verbose log level : "arduino.logLevel": "verbose"

2. delete(if you modified it, please backup it first) arduino.json&launch.json
3. RE-plug in your device, the arduino.json should be generated for you like:
{
"board": "arduino:samd:mzero_pro_bl_dbg",
"port": "COM12",
"sketch": "app\app.ino"
}

4. Press F5, and choose arduino, you should get detailed log from output view and debug console view, give us the logs from both view, thanks.

@fluentart , have you got this resolved?

@fluentart is it fix work now ?

I have what looks like exactly the same issue on Manjaro (Arch) Linux x64, also trying to debug with an M0 Pro board. I built the extension from source and successfully debugged the vscode-arduino project to track down the exception. It's thrown in vendor/node-usb-native/lib/detector.js at line 47 detection.find.apply(detection, args); because find is undefined.

This seems to be because vendor/node-usb-native/binding.gyp defines DISABLE_USB_DETECTOR for OS=='linux', so all the usb-detection bindings in vendor/node-usb-native/lib/bindings.js are undefined, which includes find.

With that info I dual-booted into Win8.1 x64 on the same laptop and installed the Arduino IDE, VSCode, the vscode-arduino extension and loaded the same project, and debugging the same code for the same M0 Pro board worked perfectly. So it seems to be a linux-specific issue. Looking at the blame for binding.gyp led me to a comment in commit e2ec7b5 "disable usb detector in linux since it is not supported now".

Surely debugging support shouldn't depend on hotplug auto-detection of usb devices if we manually configure the board and port?

I am also getting this error on Linux, trying to debug a SAMD21 board. Arduino debugging on Linux is broken with this fault.

As I was trying out the new segger-less debugging feature in the Arduino extension, I met the same error, on
