The same procedure works fine with an ESP32. One other important thing to keep in mind is that the serial bootloader uses UART0 RXD0/TXD0 as the usual/default method to load images into flash, and these pins are fixed The ESP32 downloads firmware via UART0 (TX0 (GPIO1) and RXD (GPIO3) ) by default. 3V VDD_SPI Flash , the GIO12(MTDI) If you need two serial ports in the ESP32, you can use: TX0 and RX0: GPIO 1 and GPIO 3; TX2 and RX2: GPIO 17 and GPIO 16; RX pin, TX pin); Example for initializing two serial ports: #define RXD2 16 #define TXD2 17 #define RXD0 3 #define TXD0 1 void setup() { Serial1. If I connect the ESP-PROG to the dev kit, open the programming serial port, and press/release both RST/BOOT programming mode is I used pins number 34-35 because the datasheet of the esp32 describes the RXD0 and the TXD0 with these pins, but i didn't realize that they are mapped like GPIO 1 and 3.
