    Still the same response I'm afraid.

    ....\esptool-master\esptool.py --port COm9 --no-stub chip_id
    esptool.py v2.3-dev
    Connecting........__.............................................__

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

    I think we can say there is no response.

    Thanks again for the support.

    Hi thanks for the suggestion, erase also uses the esptool, so I get the same problem:

    ....\esptool-master\esptool.py --port COM9 --baud 115200 erase_flash
    esptool.py v2.3-dev
    Connecting........__.............................................__

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

    Thanks for your help.

    Hi thanks for the comments, its a ESP VROOM-32 dev board with boot with two buttons boot and en. I've tried varios combinations of the buttons. when writing or trying to erase with no success. As I mentioned previously it worked without touching these. I checked the 'Actual Flash' section and that implies that this would be the case. So I am of the opinion, I am stuffed.

    I assume there is no other tool other than the esptool to write to the device?

    On the upside, for them, there is a happy ebayer in china who has had an order for a new one.

    Thanks for all the help given.

    Hi I cannot connect with Putty or any other serial monitor. The espressif boot writer gives the following output:

    CONNECT BAUD: 115200

    .....__.............................................__[2018-02-05 20:12:36,078][ESP8266Loader_spi[1]][espD­ownloader.pyo][line:351][ERROR]: Chip sync error: Failed to connect to ESP32: Timed out waiting for packet header

    Not sure if it helps though.

    Any help appreciated Thanks

    My esp23 was working fine running espruino, but after doing some interfacing which seemed to work I now can not connect to it via the ide. I decided to reflash as a similar thing had=s happened before when I used the esp8266, and reflashing sorted it.

    However using the esptool I just get:
    esptool.py v2.3-dev
    Connecting........__.............................................__

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

    I had this working, its an esp32 dev board with a boot and rest button. I think its an espressif dev c board. I did not touch the buttons before when I initially loaded the esspruino onto it.

    Any help appreciated or have I bricked the device?

    Thanks in advance
