With a good cable and the right driver installed, your PC shoud present a COM port even if you would completely remove the ESP32 module from the board, because the USB communication is not handled by the ESP32.

You might just need to install a driver for the USB to serial chip on your dev board.

So if one dev board works and another one doesn't, that does not necessarily mean the board is defective. Although the ESP32 module may be the same, you might have a dev board with a different USB to serial converter than other devices you might have tested on your computer. Without a driver the chip probably turns up as unsupported or unrecognised device in your hardware list. If you have a driver for that chip instaled, otherwise it won't work. This chip communicates with your computer, resulting in the creation of a virtual COM port.

A dev board typically includes some sort of USB to serial converter chip (sometimes refered to as FTDI). It has a FTDI chip on board, for which you need a virtual COM port driver, as I understand it. This is not applicable to the ESP32 Ethernet Kit.

Don't just check if it charges your phone, but check if you are actually able to transfer data.Ģ) The USB connection is not handled by the ESP32, as an ESP32 only has serial lines (rx and tx), no USB. The CP210x drivers work when you have a USB-to-UART bridge, as in ESP32-PICO-KIT for example. So make sure you have a 'real' USB cable by testing it on another device. If you would use a cable like that, the result would be what you described. I assume these have only 2 out of 4 wires: ground and +5V, but no data lines. $IDF_PATH/components/esptool_py/esptool/esptool.Apart from what kolban said, I would like to add two comments:ġ) Nowadays there are a lot of cheap (Chinese) USB cables that can only be used for charging or powering devices. My short test for all existing ports showed the error:

The esptool.py used reset with DTR and RTS and I suspect this part did not work correct, because any print of '.' or '_' showed a (fatal) error.

Therefore, go to Silicon's download page for CP210x USB to UART Bridge VCP Drivers to get a copy for your computer. In order to flash your program to your ESP32 Development Board, you will also need to have CP210x USB to UART Bridge VCP Driver installed on your computer. I changed from Arduino to esp-idf and got the same issue.Īfter some analysis, I separated the problem: I think the esptool.py didn't work correct with the cp210x drivers. Installing a CP210x USB to UART Bridge VCP Driver. In the meantime I tested three M5StickC and can not program anyone without "Connect G0 pin to GND".
