Stuck with debugging ESP32-S3 in VS-Code

[Remyhx]

Hi,

I bought a ESP32-S3 development board to test the USB connection for flashing/debugging and I can flash to the board, but am stuck debugging it. The documentation only mentions steps for eclips and the command line to work.

I am working on a Mac, updated to the latest master IDF. (ESP-IDF v5.1-dev-992-gaf28c1fa21)

My launch.json:

Code: Select all

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "ESP32 OpenOCD",
      "type": "cppdbg",
      "request": "launch",
      "miDebuggerPath": "/Users/remyhurx/.espressif/tools/xtensa-esp32s3-elf/esp-2022r1-11.2.0/xtensa-esp32s3-elf/bin/xtensa-esp32s3-elf-gdb",
      "cwd": "${workspaceFolder}/build",
      //change the name of the elf file as required
      "program": "/Users/remyhurx/Esp-proj/testdebug/build/testdebug.elf",
      "setupCommands": [
        {
          "description": "Enable pretty-printing for gdb",
          "text": "-enable-pretty-printing",
          "ignoreFailures": true
        },
        {
          "text": "target remote :3333"
        },
        {
          "text": "set remote hardware-watchpoint-limit 2"
        },
        {
          "text": "monitor reset halt"
        },
        {
          "text": "flushregs"
        }
      ],
      "externalConsole": false,

      "logging": {
        // "trace": true,
        // "traceResponse": true,
        //"engineLogging": true
      }
    }
  ]
}

Inside Vscode I start openocd one time:

Code: Select all

openocd -f board/esp32s3-builtin.cfg

That results in:

Then when I build, flash and monitor everything goes well. I go to the debug part at the left.(Run and debug). Press the green play button with the profile next to it and it returns:

Unable to start debugging. Program path '/Users/remyhurx/Esp-proj/testdebug/build/testdebug.elf' is missing or invalid.

GDB failed with message: I'm sorry, Dave, I can't do that. Symbol format `elf32-xtensa-le' unknown.

This may occur if the process's executable was changed after the process was started, such as when installing an update. Try re-launching the application or restarting the machine.

In the terminal:

What to do?

I have the same problem on MacOS X 12.6.

I can debug fine with "idf.py gdb" so not sure why this is happening...

Hi,

I'm also getting the same problem. But i'm able to debug with ESP32 module. Here i m giving the log for your reference.

cmd

openocd -f board/esp32s3-builtin.cfg

if anyone provide the solution it will be really helpful for me.
