Hello,
I designed a circuit that contains ESP32-WROOM-32D to be programmed using CP2102N-A01-GQFN28 but it didn't work and I am not able to program it
while programming, I connect GPIO0 to "PROG" (JP1) using a pin header jumper
could someone help me to find the problem?
Attached the part of my schematic that contains the programing circuit
I can't program my ESP32-WROOM-32D

What happens if you manually ground IO0? If you run a terminal program on your PC on that serial port and you reset the ESP32, do you see anything?

Sorry for replying late
I didn't get anything using USB on the terminal even by connecting GPIO0 to GND directly.
I contacted the technical support of the manufacturer of CP2102 ( Siliconlabs ) and they found a mistake in the circuit of CP2102.
the circuit after being modified is attached
do you think that there is any other mistake in the circuit of ESP programing?

How are you powering the ESP32? Presumably you have a regulator somewhere? Where do you derive 3.3V ?
