I've tried to create a small breakout board for the ESP32-WROVER-E with (what I believe) only the most minimalistic logics. Unfortunately however, I do get the following error when trying to program the microcontroller: "A fatal error occurred: Failed to connect to ESP32: Timed out waiti...
If this does not work try to bypass the FTDI chip, e.g. by connecting directly an USB to TTL cable (4 wires VCC, TX, RX, GND) to ESP-32 (VCC5, RX, TX, any GND, select Esp-32 Dev Module as board in arduino gui).In this way my board works also at full flashing speed and...
