Device Description

No attachment

Hardware Configuration

no attachement

Version

latest master (checkout manually)

IDE Name

Arduino ide

Operating System

linux arch

Flash frequency

80 mhz

PSRAM enabled

no

Description

Serial println and write stop working after upgrade to version 3.1.1 worked on 3.1.0
upload works with the arduino ide

Sketch

const long SERIAL_BPS = 115200;

void setup() {
  Serial.begin(SERIAL_BPS);
  delay(3000);
  Serial.println(USB_PRODUCT);

}

void loop() {
  Serial.println("Red");
  Serial.println("Green");
  Serial.println("Blue");

}

Debug Message

NO debug messages.

Other Steps to Reproduce

The variant esp32-s3-zero have USB_SERIAL defined as empty #define USB_SERIAL ""

The waveshare esp32-c3-zero still works.

I have checked existing issues, online documentation and the Troubleshooting Guide

Please go into Arduino preferences and set verbose output during compilation. Post the very first line of your log (with -dump-prefs) here.
Does the default esp32-s3 dev module definition work properly for you?

First line of compilation
FQBN: esp32:esp32:waveshare_esp32_s3_zero
Using board 'waveshare_esp32_s3_zero' from platform in folder: /home/rho/.arduino15/packages/esp32/hardware/esp32/3.1.1
Using core 'esp32' from platform in folder: /home/rho/.arduino15/packages/esp32/hardware/esp32/3.1.1

Yes when using dev the serial works:

FQBN: esp32:esp32:esp32s3:CDCOnBoot=cdc
Using board 'esp32s3' from platform in folder: /home/rho/.arduino15/packages/esp32/hardware/esp32/3.1.1
Using core 'esp32' from platform in folder: /home/rho/.arduino15/packages/esp32/hardware/esp32/3.1.1

If you are going to make any change to the variant file the rgb order is also wrong it is red green blue.
RGB_BUILTIN_LED_COLOR_ORDER

I have several zero boards non of the works so believe it is a software problem.

[lbernstone]

RGB color order is fixed in #10822
You do not have CDC on boot set when using the waveshare_esp32_s3_zero, or is it not registering properly?
The variant file needs to be fixed by someone that actually owns the board, so I will not be making any changes to it.

Thanks when turning on cdc it works again. I have some problems with the arduino ide when more than one is open board settings flips around.

My suggestion would be to:

• Select ESP32S3 Dev Module board,
• Enable CDC on Boot
• Add build_opt.h file to your project with just a line -DRGB_BUILTIN_LED_COLOR_ORDER=LED_COLOR_ORDER_RGB

build_opt.h file will conatain options that will be included in the gcc command line.
In this case, it will define the LED RGB order for your board.
