Hello,

This seems really easy but it drive me crazy … i’m unable to print on serial monitor below is what i can see only

ESP-ROM:esp32s3-20210327
Build:Mar 27 2021
rst:0x15 (USB_UART_CHIP_RESET),boot:0x18 (SPI_FAST_FLASH_BOOT)
Saved PC:0x40378a96
SPIWP:0xee
mode:DIO, clock div:1
load:0x3fce2820,len:0x10f0
load:0x403c8700,len:0x4
load:0x403c8704,len:0xbec
load:0x403cb700,len:0x2fb8
entry 0x403c88ac’

Note that the baud rate is correct , the usb is working , i have erase the flash but still nothing is working … if i tried with RGB LED all is fine … any lead please ?? I have reinstall the Arduino IDE but no lucky… i have tried also with the vs code below are the error

ELF file SHA256: 817f2fa1c418e81d

E (111) esp_core_dump_flash: Core dump flash config is corrupted! CRC=0x7bd5c66f instead of 0x0

It doesn’t look like your code was successfully uploaded and started. Perhaps a different choice of board would work.

3

The code was successfully uploaded and i have a correct board choosen … why the rgb led is working ? and not the serial terminal ?

4

Have you pressed the RST button?

5

These two error messages suggest that your code was not properly uploaded and started.

Have you ever managed to successfully upload and run any example of code that uses the serial monitor, with this particular ESP32 module?

If so, try that example again, and post all the messages that appear on the serial monitor, during and after the upload process.
