ESP32-WROOM-32 Unable to upload program

[Elkez]

Please, give me an advice.
I am trying to program an ESP32-WROOM-32.
When uploading via the Arduino IDE, a message appears:

Sketch uses 263705 bytes (20%) of program storage space. The maximum is 1310720 bytes.
Global variables use 21400 bytes (6%) of dynamic memory, leaving 306280 bytes for local variables. The maximum is 327680 bytes.
esptool.py v4.5.1
Serial port COM1
Connecting……………………………..

A fatal error occurred: Failed to connect to ESP32: No serial data received.
For troubleshooting steps visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html
Failed uploading: uploading error: exit status 2

What am I doing wrong?
Thanks for the help.

I found that the module does not find the connection to the PC port.
I keep looking.

Hi
I don’t think so anymore.
I used a mobile power cable without connecting the data wires.
