ESP32S3 Serial Monitor connected successfully but does not print to the serial port

ran.an · September 3, 2023, 6:53pm

Dear Expert, could you advice why Platformio monitor does not print, while Arduino works ok with the same simple code? Does my platformio.ini file miss any necessary setting?

My device is ESP32-S3FH4R2 with 4 MB flash and 2 MB PSRAM inside.

This is my main.cpp code:

void setup() {
  Serial.begin(115200);
  delay(2000);
  Serial.println("Started");
  Serial.println("I am talking.............................\n");
}
void loop() {}

This is what Arduino monitor shows:

The main.cpp codes are very simple. It seems to me a setting problem, but I am not sure why Platformio monitor shows totally different outputs in comparing to Arduino. I couldn’t figure out what difference cause this problem.

Thank You in advance

This is not equivalent to what you have selected in the Arduino IDE. Specifically, the setting

github.com

platformio/platform-espressif32/blob/6186d2ce982ce578a89e77f420b306c8b3cc2905/boards/adafruit_feather_esp32s3.json#L10-L10


      
          "-DARDUINO_USB_CDC_ON_BOOT=1",

But you have “USB CDC On Boot: Disabled” which maps to the value 0.

github.com

espressif/arduino-esp32/blob/720be7599f23ccf26a09bb371af833b44cf4627f/boards.txt#L148-L151


      
          esp32s3.menu.CDCOnBoot.default=Disabled
          esp32s3.menu.CDCOnBoot.default.build.cdc_on_boot=0
          esp32s3.menu.CDCOnBoot.cdc=Enabled
          esp32s3.menu.CDCOnBoot.cdc.build.cdc_on_boot=1

You might aos need to equivalently set “USB Mode: Hardware CDC and JTAG”, which is -DARDUINO_USB_MODE=1 per here.

So all in all, you should rather use this platformio.ini.

[env:adafruit_feather_esp32s3]
platform = espressif32
board = adafruit_feather_esp32s3
build_unflags = -DARDUINO_USB_CDC_ON_BOOT=1
build_flags =
   -DARDUINO_USB_CDC_ON_BOOT=0
   -DARDUINO_USB_MODE=1
framework = arduino
monitor_speed = 115200

Dear Maxgerhardt, thanks for the quick message.

After I tried this new platformio.ini, the monitor still does not print. Could you further look into this?

maxgerhardt:

[env:adafruit_feather_esp32s3]

I also tried another board type (esp32-s3-devkitc-1) in platformio.ini. And, resize the flash to 4MB to fit with my ESP32-S3FH4R2 MCU. But, still no luck.

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
board_upload.flash_size=4MB
framework = arduino
monitor_speed = 115200

The platformio monitor outputs was ok but no print-outs:

Then, I added these flags

but still not working.

The new platformio.ini is like so:

[env:esp32-s3-devkitc-1]
platform = espressif32
board = esp32-s3-devkitc-1
board_upload.flash_size=4MB
build_unflags = -DARDUINO_USB_CDC_ON_BOOT=1
build_flags =
   -DARDUINO_USB_CDC_ON_BOOT=0
   -DARDUINO_USB_MODE=1
framework = arduino
monitor_speed = 115200

The platformio monitor shows the same with no print:
