A fatal error occurred: Failed to connect to Espressif device: Invalid head of packet (0x00): Possible serial noise or corruption. For troubleshooting steps visit: https://github.com/espressif/esptool#troubleshooting

Do you have any other information from investigating this?

I bought 4 wemos d1 mini and only one have this issue

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

Sorry I'm newby, but I think that the problem is because I've created *.bin in IDE by "compliled program export", and I've put it with: /esptool.py -p /dev/ttyUSB1 write_flash --flash_mode=dio --flash_size=4MB 0x00000 dht22.ino.d1_mini.bin. I think that maybe I've erase some bootloader located at 0x00000, but I'm not sure because I don't know which board it was... If it is the reason of problem how can I write a new bootloader if there is a problem with connection?

The board is bliking, but there is problem to connect via usb. I don't know if I bought it dead or I've "burned" it...

Hello @Wi5eJ4rl,

if you have 4 identical boards and only 1 has his issue, it is a sign of faulty hardware.

Can you try connecting with a serial terminal program and see what the board is printing? There are many serial terminal programs suitable for debugging & serial interaction. The pySerial module (which is required for esptool) includes one such command line terminal program - miniterm.py. Run python -m serial.tools.miniterm "PORT" 74880, you should see a boot log like this when you reset the chip. If not, please post the output here.

Thank you @radimkarnis for your reply.

I'm not sure but the output is similar but longer: ` python3 -m serial.tools.miniterm /dev/ttyUSB0 74880 --- Miniterm on /dev/ttyUSB0 74880,8,N,1 --- --- Quit: Ctrl+] | Menu: Ctrl+T | Help: Ctrl+T followed by Ctrl+H --- -�-�-�-�-�-�-�-�-�-�-�-�-�-�-�-�-�␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀16 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 016 tail 8 chksum 0xe5 load 0␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀␀sum 0xd8 csum 0xd8

If I understand, maybe I've erased a bootloader? I've read that in ESP-12 it is located in 0x0000 so if I put there sketch, it erases bootloader. I also find information that, if I want to flash new bootloader, the board can switch to boot mode by it self - mine not - and there is the 'force' method with soldering GPIO 0 with GND - this also do nothing... So I don't know what can I do...

The other option is, the chip CH340 is fine so it "talking" with computer, or maybe the this chip is failure and the ESP12 board is fine.... I don't know...

I'm wandering if I can fix this board or it's a junk...

radimkarnis commented 2 years ago

Thank you for the log. The lines of the log look ok to me, the chip is definitely booting (it is weird these lines are repeated that many times).

... and a lot of '␀␀␀' some char...

Anyway, baud rate 74880 is what the Espressif firmware bootloader uses. Hence, at that rate, you can decipher its messages but see everything else as gibberish. The apps on top of the Espressif SDK (e.g. Arduino sketch) talk at 115200. That's why you see the following messages as gibberish at that rate.

If you retry the miniterm command with 115200 baud rate, maybe we get more information.

method with soldering GPIO 0 with GND - this also do nothing

If you disconnect everything from the board, bridge GPIO0 (marked D3 on the board) and GND, and reset the chip it doesn't switch into the download mode? (more information about this process is here)

Hello again,

With python3 -m serial.tools.miniterm /dev/ttyUSB1 115200 command I get:

  1. couple of "ERROR" lines
  2. Rubbish - I think that this is in 74880 baud rate
  3. "ready" line in loop

But, if I set the 74880 baud rate, plug board in usb, connect D3 to GND, reset, I get "boot mode:(1,7)" in loop, so I don't understand. If I do the same and I put esptool.py -p /dev/ttyUSB1 chip_id I get again nothing:

esptool.py v3.2 Serial port /dev/ttyUSB1 Connecting......................................

A fatal error occurred: Failed to connect to Espressif device: Invalid head of packet (0x00): Possible serial noise or corruption. For troubleshooting steps visit: https://github.com/espressif/esptool#troubleshooting

I tried also connect it with windows but it the same problem. What I can do?

Wi5eJ4rl commented 2 years ago

What is more, if I have blank board (without any bridge in pins), I have tree (or more) "states" after reset:

and after reset one of above... Maybe there is a problem with memory? Some "bad sectors"? This is not stable board...

radimkarnis commented 2 years ago

if I set the 74880 baud rate, plug board in usb, connect D3 to GND, reset, I get "boot mode:(1,7)" in loop

boot mode:(1,X) means switching to download mode works (see this page for explanation), but the looping message and other flaky logs are very unusual.

This is some weird behavior, I am sorry, but at this point it is clearly not an esptool issue, but a HW one. I would probably advise you to save the hassle of digging through this and just replace the board.

Ok, thanks for your help!

I know it is closed, in my case it helped to connect 300 Ohm resistor from 3,3v to D4 aka GPIO 2, on a D1 mini, Chip was ESP8266EX.
