Serial.println not working

Advanced Solutions Debugging

Running my first project on Platformio and mostly things are working well but when using the serial monitor, I am only receiving internal logs ‘log_i’ whereas anything using println is not shown in the logs. Is there a setting I’m missing?

The board I am using is a diymore ESP32-c3 super mini. Although, it’s not showing anything on the diymore site for this board. Suspect it’s a knockoff.

Amazon link for the board

#platform.ini

[env:esp32c3]
platform = espressif32
board = esp32-c3-devkitm-1
framework = arduino
upload_speed = 921600
upload_port = /dev/cu.usbmodem14601
monitor_speed = 115200
monitor_port = /dev/cu.usbmodem14601
build_flags =
  -DCORE_DEBUG_LEVEL=5
  -DARDUINO_USB_MODE=1
  -DARDUINO_USB_CDC_ON_BOOT=0
lib_deps =
  fastled/FastLED @ ^3.6.0

If that’s a mini board, I doubt there’s a dedicated usb-to-serial chip on there, meaning the ESP32-C3 is the USB CDC, meaning you should flip

to 1.

I’ll give it a go and revert back

Thank you!
Solved many headaches today.
