Cannot flash via JTAG (VSC-849)

See original GitHub issue

Pre Bug Report Checklist

Make sure you have searched for existing bugs and features request before you post an issue.
This is a bug report for the ESP-IDF Visual Studio Code extension and not an ESP-IDF bug report.
I’ve read the docs and found no information that could have helped solving the issue.

Describe the bug I am working with a ESP32-WROVER-KIT which is configured with the JTAG interface as for the docs. I can successfully flash the firmware using the command line:

openocd -d3 -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover-kit-3.3v.cfg

Instead, flashing from VSCode fails.

To Reproduce I have tried several settings.json configurations. This one looks like the most reasonable:

{
    "idf.adapterTargetName": "esp32",
    "idf.openOcdDebugLevel": 3,
    "idf.openOcdConfigs": [
        "board/esp32-wrover-kit-3.3v.cfg"
    ],
    "cmake.configureOnOpen": false,
}

From process explorer, I can see the command line launched from VSCode is the following:

openocd -d3 -f board/esp32-wrover-kit-3.3v.cfg

Anyway, the flashing process starts but it hangs.

The complete (level 3) log is the following:

I also did another test:

Launched openocd -d3 -f board/esp32-wrover-kit-3.3v.cfg from the Expressif command line
Started the flashing procedure from VSCode

In the command line I see:

The last line before start flashing from VSCode:
