getting the debugger working in VS Code

[mzimmers]

Hi all -

I'm delighted that we now have an interactive debugger for the ESP32. I've read https://github.com/espressif/vscode-esp ... bugging.md and they mostly make sense, but as a newcomer to this stuff, I could use a little more detail.

I'm using a ESP32-WROOM-32D board. The online help suggested I use the board/esp32-wrover-kit-1.8v.cfg, so I chose that from the command palette. (This is a file, right? I can't find it anywhere.)

This is the contents of my settings.json file:

Code: Select all

{
    "idf.adapterTargetName": "esp32",
    "workbench.colorTheme": "Visual Studio Light",
    "idf.espIdfPath": "/home/mzimmers/esp/esp-idf",
    "idf.pythonBinPath": "/home/mzimmers/.espressif/python_env/idf4.3_py3.8_env/bin/python",
    "idf.toolsPath": "/home/mzimmers/.espressif",
    "idf.customExtraPaths": "/home/mzimmers/.espressif/tools/xtensa-esp32-elf/esp-2021r1-8.4.0/xtensa-esp32-elf/bin:/home/mzimmers/.espressif/tools/xtensa-esp32s2-elf/esp-2021r1-8.4.0/xtensa-esp32s2-elf/bin:/home/mzimmers/.espressif/tools/xtensa-esp32s3-elf/esp-2021r1-8.4.0/xtensa-esp32s3-elf/bin:/home/mzimmers/.espressif/tools/riscv32-esp-elf/esp-2021r1-8.4.0/riscv32-esp-elf/bin:/home/mzimmers/.espressif/tools/esp32ulp-elf/2.28.51-esp-20191205/esp32ulp-elf-binutils/bin:/home/mzimmers/.espressif/tools/esp32s2ulp-elf/2.28.51-esp-20191205/esp32s2ulp-elf-binutils/bin:/home/mzimmers/.espressif/tools/openocd-esp32/v0.10.0-esp32-20210401/openocd-esp32/bin",
    "idf.customExtraVars": "{\"OPENOCD_SCRIPTS\":\"/home/mzimmers/.espressif/tools/openocd-esp32/v0.10.0-esp32-20210401/openocd-esp32/share/openocd/scripts\"}",
    "idf.gitPath": "git",
    "idf.flashType": "UART",
    "idf.saveScope": 2,
    "C_Cpp.autoAddFileAssociations": false
}

Anyway, if anyone know of some supplementary information for getting this going (or can already see what I'm doing wrong), I'd appreciate knowing about it. Thanks...

What kind of issue are you having with debugging ?

To configure the debug adapter, you use the settings in your launch.json as per Visual Studio Code approach.

Take a look at https://github.com/espressif/vscode-esp ... BUGGING.md

Hi bignacio - sorry for the late reply; lots of unrelated tasks going on right now.

My current issue with the debugger is when I get to the step where I press F5, it prompts me to select an environment, and the only choices are:

C++ (GDB/LLDB)
C++ (Windows)

I imagine this is something to do with a configuration file, but I thought I had followed the instructions faithfully, so I don't know.

Thanks...

[ESP_bignacio]

If it is asking to choose this it is probably because visual studio code doesn't find a launch.json for the current project.

Is there a .vscode/launch.json ?

Are you opening one ESP-IDF project or several projects at the same time ?

[mzimmers]

Hi bignacio -

Yes, I have a launch.json file. I'm only opening one project.

The behavior has changed -- now when I press F5, I get an error "The preLaunchTask 'C/C++: arm-none-eabi-g++ build active file' terminated with exit code -1.

Not sure what I've done to introduce this behavior...

[mzimmers]

I'd like to return to this issue, please. When I try to start the debugger, I get this error:

debug.PNG (178.14 KiB) Viewed 32708 times

Any ideas what I'm doing wrong? Thanks...

Yuri R made a nice detailed video on how to setup the ESP-PROG on VS Code, it worked for me at least

Hi ProtonBoarder -

That is indeed a good video -- it does answer a few questions.

I'm trying to use his automated preRun task:

Code: Select all

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "preRun",
            "type": "shell",
            "windows": {
                "command": "clear & start openocd -c \"set ESP_RTOS none\" -f board/esp32-wrover-kit-3.3v.cfg & exit"
            }
        }
    ]
}

but I'm getting an error:

Code: Select all

At line:1 char:7
+ clear & start openocd -c set ESP_RTOS none -f board/esp32-wrover-kit- ...
+       ~
The ampersand (&) character is not allowed. The & operator is reserved for future use; wrap an ampersand in double quotation marks ("&") to pass it as part of a string.

I've tried escaping the ampersand, but no change in results. Any idea what's wrong here?

Thanks...

EDIT: after some experimentation, I enclosed the ampersand in single quotes:

Code: Select all

                "command": "clear '&' start openocd -c \"set ESP_RTOS none\" -f board/esp32-wrover-kit-3.3v.cfg '&' exit"

That seems to have fixed it. Evidently the author of the video was using a basic Windows shell, and my system is configured for PowerShell, which doesn't like the naked ampersand.

[lg.lindstrom]

I've tried his command line, and your modification of his command:

Code: Select all

 "command": "clear '&' start openocd -c \"set ESP_RTOS none\" -f board/esp32-wrover-kit-3.3v.cfg '&' exit"

nothing works for me.
I agree on the conclusion that different shells are used.

VsCode must have a way to control which shell that is used. I have searched among VsCode settings without understand which to use/change.

Have you looked into this ?

[ashelman-ec]

In the Windows terminal, the ampersand is used to separate two commands on one line.

In PowerShell, a semicolon is used instead.

Try this instead:

Code: Select all

 "command": "clear ; start openocd -c \"set ESP_RTOS none\" -f board/esp32-wrover-kit-3.3v.cfg ; exit"
