What is the expected behaviour?

Should show chip_id

Do you have any other information from investigating this?

• Voltage is perfect through the whole circuit, so no energy drainage problems
• None of the commands (chip_id, flash_id, read_mac, write_flash) work, all of them spill out the same output.
• Tried with --before no_reset - says invalid head for packets every time for every cmd
• I'm quite new to ESP and microprocessors :/

Is there any other information you can think of which will help us reproduce this problem?

I'm flashing throught arduino pro micro, using 3.3v regulator (getting 3.25-3.3v through out the circuit)

Same error here after running:

Found 3 serial ports

A fatal error occurred: Timed out waiting for packet content

I have a WEMOS D1 R2.

I think your issue is slightly different, as you're getting an initial response from the unit (the chip type is returning values).

There are a series of problems being reported where esptool isn't flashing units that have gone into deep sleep or are stuck in a wdt reset loop (see #193, #351 and #380). In my case I found that the nodemcu flash tool worked all the time, but that I could use esptool by following the hard reset described by @projectgus in #380

Obviously this is not an ideal approach and it would be great to work out how the nodemcu flash utility is managing to flash every time, but can you try the hard reset and see if that allows you to flash?

Hi @veiico ,

The trace you posted seems to indicate that nothing is being received from the ESP8266 over serial.

How are you resetting the ESP8266 into bootloader mode? This has to be done with either GPIOs or RTS/DTR signals, and I don't think using an Arduino as a usb/serial adapter allows for this. See https://github.com/espressif/esptool/wiki/ESP8266-Boot-Mode-Selection

Are you disabling the Arduino's AVR microcontroller as well, or using it as a serial relay using a sketch?

If you can, try to get hold of dedicated 3.3V USB/serial adapter board or cable to flash with.

Closing due to a lack of updates.

I Got the solution, watch this video on youtube and u will get it, i suffered from the same problem too but this video resolved the problem, anyways thanks me later, the link is below:
