Dear all ,

I am using ESP32-S2 WROOM development board in one of the project. I used to do flashing through the on board usb earlier. But now I want to use the ESP32Prog for the flashing Purpose. But I am getting the error as Chip sync error. Please note following connection which I have made.

ESP32S2 WROOM ESP32PROG board
TX ------------------> ESP_TXD
RX -----------------> ESP_RXD
EN --------------------> ESP_EN
3V3 ----------------------- >VDD
IO0 -------------------------> ESP_IO0

I have done following settings from the idf.py menuconfig ---> Serial Flasher

1) [*] Disable Download stub
Flash SPI mode -> DIO
Flash SPI Speed -> 40MHz
Flash Size -> 16Mb
idf.py monitor baudrate 115200

Please help to solve this issue. I am stuck on this issue. Your help is highly appreciated. :)
