Thanks for the reply.

- Does the ESP32-C3 get power at all? Check your rails.
Yes, I'm receiving the power; 3.3V on all VCC pins

- Does the ESP32-C3 get taken out of reset? Check the EN pin.
Yes. When I power up the system with USB plugged in and with pressed reset button; I can hear the usb plug ...

I have designed a custom board using esp32-c3fh4 but I'm unable to program the controller. Tried both method (Uisng usb, and uart) but nothing worked. Not sure how to debug. Help would be appreciated.
