Not Able to Program ESP32

[brn100]

Dear all,

I have a great issue while wanted to program ESP32-WROOM-32E MCU idle, without using any development boards. I am using CH340G USB-to-UART adapter for external connection. In order to supply ESP32, I am using LM1117 LDO regulator(5V to 3.3V).

I continuously get the following message on serial monitor when I wanted to program my ESP32-WROOM-32E over Arduino:

Rebooting...

Apart from that, the other problem is when I wanted to upload a code into the chip, I get the following error:

esptool.py v3.3-dev
Serial port /dev/ttyUSB0
Connecting.....................................An error occurred while uploading the sketch
.
A fatal error occurred: Failed to connect to ESP32: No serial data received.

What do you think about the problem? I had attached the schematic that I used.

Thanks for your attention,

Can you check what happens if you manually ground GPIO0, reset the ESP32 and then re-try programming it?
