Could not detect the GDB tool path

[chked]

Could not detect the DGB tool path message appears in Exception Decoder Output window. IDE is 2.3.1, board ESP8266.
How debug output can be enabled? This could be helpful to find out such issures.

Thank you for reporting it.

Could not detect the DGB tool path message appears in Exception Decoder Output window

Please send the complete decoder output as a markdown string.

IDE is 2.3.1, board ESP8266.

It would be interesting to know what your board selection IDE2 is. You can make a screenshot, but executing the (Developer) Arduino: Dump the Board List command and pasting the output here is even better.

To execute a command:

1. Press the Ctrl+Shift+P keyboard shortcut (Command+Shift+P for macOS users) to open the "Command Palette".
2. Select the "(Developer) Arduino: Dump the Board List" command from the menu.
3. Press Enter.

ℹ️ See Arduino IDE's Advanced Usage for more details.

How debug output can be enabled?

See #10 (comment) for how to enable the log outputs.

Further questions:

• Which platform do you use, and which version?
• Does verify/upload work in the Arduino IDE?
• Do you have manually installed cores (in your sketchbook)?

The decoder output is

1. After start
   ESP Exception Decoder
   Sketch: Test FQBN: esp8266:esp8266:esp12
   The summary of the previous compilation is unavailable. Compile the sketch
2. After compiling the sketch
   ESP Exception Decoder
   Sketch: Test FQBN: esp8266:esp8266:esp12
   Could not detect the DGB tool path

Used versions:
Arduino IDE 2.3.1
esp8266 community 3.1.2

Verify/Upload works.

There are no manually installed cores.

@chked, what happens when you select another board? For example, Generic ESP8266 Module (esp8266:esp8266:generic). Do you still see the same error in not detecting the gdb tool path?

By the way, there is a typo: DGB tool path. It should be GDB tool path (✅ fixed at acecf05#diff-f0843b65305eff43610dfeb65f83a76b3c46fa542dbebd00fdde5fe70afb6526R74)

Please take a screenshot of your boards manager while you hover over the esp8266 platform's description:

@chked, could you please provide the following info 👆?

It would be great to see what's in the output logs. Please reference #10 (comment) on how to enable the logging. Thanks!

[chked]

Thank you for reply. I got it yesterday. When I selected a ESP32 board, the error message disappeared, on every ESP8266 board, the message is still there. The reason was that the extensa...gdb.exe was not in my toolchain package. I reinstalled the toolchain package, now everything works fine.
Perhaps, more detailed messages could help to find such problems easier.

1. FQBN: esp8266:esp8266:esp12

I have installed all ESP8266 versions (https://arduino.esp8266.com/stable/package_esp8266com_index.json) but could not find a board with esp12 board ID.
