  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 20:12:36,079][ESP8266Loader_spi[1]][espDownloader.pyo][line:395][ERROR]: ESP32 Chip sync error esp_sync_blocking.

  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
