FTDI USB Converter + ESP32 Dev. Kit DOIT

Postby allexo » Thu Jul 05, 2018 10:20 am

Sorry for the noob question.
It´s my firs contact with ESP32 and I´m trying to connect a FTDI converter to ESP32 to upload my program (instead of micro USB connector). I connected TX, RX and GND pins of FTDI to ESP32 (RX0, TX0 and GND pins rescpectively). But unfortunatally I can´t upload the program. The ESP32 not responding. Even pressing the BOOT button of dev kit. When I use the micro USB connector only if a press the BOOT button I can upload the program.
There is another thing (hardware or software) that must be done?

Below the error.

esptool.py v2.3.1
Connecting........_____....._____....._____....._____....._____....._____....._____....._____....._____....._____

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

I am about to do this soon, but haven't yet.

There are two strapping pins involved in going into programming mode. https://github.com/espressif/esptool/wi ... -Selection

Have you connected FTDI at 115200 and just see if there is the normal info on it during power up. That proves your FTDI, ground and Rx are working.
