esp 8266 devkit c Failed to connect to ESP32: Timed out waiting for packet header

Postby gooniya » Sun Jan 13, 2019 8:35 pm

Hello,

I am new to ESP32 and am trying to get started. I get the following error when trying esptool to read mac address.

Failed to connect to ESP32: Timed out waiting for packet header

I am able to use make simple_monitor from the sdk and work with AT commands so the boards serial interface seems fine and is connected to the computer properly.

I have
* powered the board separately with 5v.
* tried various combinations of boot/reset button

The board I have is from this link : https://www.espressif.com/sites/default ... de__EN.pdf

Apart from the reset/boot there are two dip switches that by default off.

Given that the basic esptool is not working I am wondering if this is a new board that is not supported yet?

Thanks in advance.
