How can I get Serial debug logging on ESP32-S3 over USB (JTAG is working)

[papakpmartin]

I was excited to see that I can do JTAG debugging on my new boards that have the ESP32-S3. I've set that up and it appears to be working nicely. However, I thought I've read that I can also see Serial debug output over that same USB, and I'm not seeing that.

My board looks like this:

{
  "build": {
    "arduino":{
      "ldscript": "esp32s3_out.ld",
      "partitions": "default_8MB.csv"
    },
    "core": "esp32",
    "extra_flags": [
      "-DARDUINO_ESP32S3_DEV",
      "-DARDUINO_USB_MODE=0"
    ],
    "f_cpu": "240000000L",
    "f_flash": "80000000L",
    "flash_mode": "qio",
    "hwids": [
      [
        "0x303A",
        "0x1001"
      ]
    ],
    "mcu": "esp32s3",
    "variant": "esp32s3"
  },
  "connectivity": [
    "wifi"
  ],
  "debug": {
    "default_tool": "esp-builtin",
    "onboard_tools": [
      "esp-builtin"
    ],
    "openocd_target": "esp32s3.cfg"
  },
  "frameworks": [
    "arduino",
    "espidf"
  ],
  "name": "ESP32-S3 Custom Board",
  "upload": {
    "flash_size": "8MB",
    "maximum_ram_size": 327680,
    "maximum_size": 8388608,
    "require_upload_port": true,
    "speed": 460800
  }
}

I also tried -DARDUINO_USB_MODE=1 in the board file above.

And my platformio.ini looks like this:

[env:esp32s3-custom-board]
platform = [email protected]
board  = esp32s3-custom-board
framework = arduino
monitor_speed = 115200
monitor_filters =
	esp32_exception_decoder
	log2file
build_type = debug
debug_speed = 12000
debug_tool = esp-builtin
debug_init_break = tbreak setup
debug_load_mode = manual

Is there something else I need to do to get Serial routed to USB?

did you try this?
-DARDUINO_USB_CDC_ON_BOOT=1

I had tried this, but it didn't work. However, I just tried again using platform = [email protected] and it seems to be working perfectly! Thanks, @homonto!
