The block labeled ESP32-S2 is a chip "ËSP32-S2 WROVER model" and I will also check with different USB to UART serial device. Might be the one which I am using now is not supplying sufficient power to ESP32-S2 module. If any other issue I will post in the same discussion.

Hi,
Find the attached file of schematic view. please, ignore the imperfection.

Actually, I am getting the below error when I am trying to program using USB to UART TTL.

I mean i have to flash the program into ESP32-S2 using USB to UART TTL. please, help me on this and also i want to know the boot button pin number in ESP32-S2 module. kindly, do the needful guys. thanks in advance.

Hi,
We are developing a application with ESP32-S2 where I have to program the ESP32-S2 custom chip. May I know the best way to program the chip and let me know the procedure. kindly, do the needful.
