Flash mode looks strange. Looks like a mismatch between mode DIO and QIO.
Try mode DOUT

My test code is the following simple lines, can you tell me which code to add to solve?

void setup(){
  Serial.begin(115200);
  Serial1.begin(9600);
}
void loop(){
}

In Arduino IDE menu there should be the option to select the flash mode. I do not use Arduino IDE so maybe it is somewhere else to select the flash mode

I've tried all the Flash modes (QIO,DIO,DOUT,QOUT), but it still doesn't work out.

@lybgo Try passing in pin numbers to use for Serial1. The defaults being picked (TX:17, RX: 18) overlap with the on-board flash (at least TX does) and that is why you are seeing a consistent reboot.

Try:
Serial1.begin(9600, SERIAL_8N1, 18, 19);

Note that pins 18 and 19 are also used for USB-JTAG.

@atanisoft I have tried your method, C3 will not restart constantly, but Serial1 cannot communicate, I have tried all pins (0-9,18,19).

Same here,

Trying to use GPIO 2 & 3, nothing happend on the pins:

Serial1.begin(115200, SERIAL_8N1, RX1, TX1);
Serial1.println("BOOT");

For the moment the only solution that I have: use function from ESP IDF into Arduino IDE, that works.

#include "C:\xxx\esp-idf\components\driver\include\driver\uart.h"

#define ECHO_UART_PORT_NUM UART_NUM_1
#define BUF_SIZE (1024)

void ESP32uart()
{
    const uart_port_t uart_num = ECHO_UART_PORT_NUM;
    uart_config_t uart_config = {
        .baud_rate = 115200,
        .data_bits = UART_DATA_8_BITS,
        .parity = UART_PARITY_DISABLE,
        .stop_bits = UART_STOP_BITS_1,
        .flow_ctrl = UART_HW_FLOWCTRL_CTS_RTS,
       .rx_flow_ctrl_thresh = 122,
    };
    // Configure UART parameters
    ESP_ERROR_CHECK(uart_driver_install(ECHO_UART_PORT_NUM, BUF_SIZE * 2, 0, 0, NULL, 0));
    ESP_ERROR_CHECK(uart_param_config(ECHO_UART_PORT_NUM, &uart_config));
    ESP_ERROR_CHECK(uart_set_pin(ECHO_UART_PORT_NUM, 2, 3, -1, -1));
}

uart_write_bytes(ECHO_UART_PORT_NUM, &rxValue[0], 6);

You should not use headers from an external idf in arduino. #include <driver/uart.h> should work and can be trusted to not have missing or conflicting symbols.

HardwareSerial is currently under refactoring.
This will solve the current issue, as well as other problems.

Please hold for the news.
It will use IDF for future fast portability with current and new SoCs in the roadmap.

## Summary
This PR is a complete reffactoring of UART Serial Hardware and respective HAL in order to use IDF instead of current Register manipulation approach. 

It  implements Arduino SerialEvent functionality. 

Fix #5287  
Fix #5273 
Fix #5519 
Fix #5247 
Fix #5403
Fix #5429
Fix #5047
