ESP32 Wroom custom PCB not working

Postby MCUism » Wed Sep 02, 2020 7:01 pm

Hello all,

I have made a design with ESP32 Wroom and CP2102-GM UART bridge. My board is getting recognized by the PC but the code is not being uploaded to the board. I am getting timed out error on the ESP32 as shown below.

The CP2102 circuitry and the RTS, DTR toggling circuit is shown below.

I am able to understand that the error I got is that ESP32 is not going into the programming mode. But how should I resolve this error?

Pleaseeeee help me out
