ESP32 + CP2102

Hello,
I have a problem uploading a program to esp32 with cp2102 over Arduino. (picture in attachments)


I tried holding the boot button and then releasing it but it didn't help. Could someone take a look at the schematic? I guess there must be a mistake in that.

Thank for any help.

If you want TX and RX to have activity lights, put them directly in line. As you have it, the lines are being pulled up. You can remove the LEDs or those resistors to test it (or cut the traces).
