Hello.
I try to use VS Code with Espressif IDF plugin for ESP32-H2-DevKitM1.

When use launch(debug) settings(file settings.json) like this:

Code: [Select all] [Expand/Collapse]

{
  "C_Cpp.intelliSenseEngine": "Tag Parser",
  "idf.adapterTargetName": "esp32h2",
  "cmake.configureOnOpen": false,
  "idf.openOcdConfigs": [
    "board/esp32h2-builtin.cfg"
  ]
}

openocd give me error, like this:

Code: [Select all] [Expand/Collapse]

[OpenOCD]
❌ Error: unable to open ftdi de ice with description '*', serial '*' at bus location '*'
C:\Espressif\tools\openocd-esp32\v0.12.0-esp32-20230419/openocd-esp32/share/openocd/scripts/target/esp_common.cfg:4: Error:

I have same error, when launch openocd from command line, like this (pass ftdi-script):
openocd.exe -f board\esp32h2-ftdi.cfg

As i think, plugin do not pass board/esp32h2-builtin.cfg builtin script correctly to open ocd.

What's wrong?
Thank you.

Found other feature:

If idf.openOcdConfigs config field do not contain reference to interface script, openocd automatically use wrong VIN/PID and can not found the device.

With VS Code config like this:

Code: [Select all] [Expand/Collapse]

{
  "C_Cpp.intelliSenseEngine": "Tag Parser",
  "idf.adapterTargetName": "custom",
  "idf.customAdapterTargetName": "esp32h2",
  "idf.flashType": "JTAG",
  "idf.portWin": "COM7",
  "idf.openOcdDebugLevel": 4,
  "idf.openOcdLaunchArgs": ["-l openocd_log.txt"],
  "cmake.configureOnOpen": false,
  "idf.openOcdConfigs": [
    "board/esp32h2-builtin.cfg"
  ]
}

OpenOCD output is:
...
Debug: 23 12 command.c:152 script_debug(): command - espusbjtag vid_pid 0x303a 0x1002
Info : 24 12 esp_usb_jtag.c:894 esp_usb_jtag_vid_pid(): esp_usb_jtag: VID set to 0x303a and PID to 0x1002

.....
Error: 119 1463 esp_usb_jtag.c:646 esp_usb_jtag_init(): esp_usb_jtag: could not find or open device!

But, for Espressif IDE with same script file (board/esp32h2-builtin.cfg) for OpenOCD, output is:

Info : only one transport option; autoselecting 'jtag'
Info : esp_usb_jtag: VID set to 0x303a and PID to 0x1001
Info : esp_usb_jtag: capabilities descriptor set to 0x2000

Info : esp_usb_jtag: serial (48:31:B7:C0:2A:E1)
Info : esp_usb_jtag: Device found. Base speed 24000KHz, div range 1 to 255

To find device correctly, type interface script explicitely:

Code: [Select all] [Expand/Collapse]

{
   ...
  "idf.openOcdConfigs": [
    "[b]interface/esp_usb_jtag.cfg[/b]",
    "board/esp32h2-builtin.cfg"
  ]
}

Hi,

Can you run the "ESP-IDF: Doctor Command" (from Command Palette) and provide me with the output? It will be copied to the clip board
