I purchased this board: https://www.aliexpress.com/item/ATMEGA32U4-ESP8266-ESP-12E-ESP12E-Badusb-TF-Micro-SD-Virtual-Keyboard-Development-Board-for-Arduino/32839674193.html?spm=a2g0s.9042311.0.0.R4hbkG

My computer picks it up as an arduino leonardo. So I uploaded the code that allows you to flash the esp board (https://gist.github.com/spacehuhn/b2b7d897550bc07b26da8464fa7f4b36.) Then I tried to use nodemcu to flash it but got the following errors:

Note:Detect serial port changed.
Note:Auto MAP serial port.Port-->COM7

Error:Serial port connect failed, please check it.

Has anyone else been able to get this board or one similar to it working? The bottom says CJMCU-3212 if that helps.

I'd like to know this as well, I haven't been able to get the nodemcu flasher to detect my mac address. I'm a bit concerned as most of the tutorials say the gpio pin is supposed to be disconnected after flashing so it doesn't enter flash mode, but it seems all the pins are permanently soldered on this AIO board. I also haven't been able to find any tutorials involving these aliexpress boards.

There is just one tutorial that I have found for this, but it is entirely in Chinese: https://www.bilibili.com/video/av22645681. If anyone understands it, I would love to figure this out as well. I've been trying to flash just the ESP8266 using a USB-to-TTL device, but haven't had any luck. According to the video, the 4 pins on the right-most side under the "CJMCU" label are Rx, Tx, Vcc, and GND respectively. I've been connecting to those four and then connecting the two circles on the top left, which I presume is to pull CH_PD up. I've been staring at this board for hours, and still haven't been able to make much progress. I'll probably try and pull the board apart once I get some better soldering equipment.

@wilson289296

As luck would have it, I speak mandarin. I've watched the video and I think I have the steps down. I'll try to get my hands on that adapter he mentioned and I'll see if it works. In short, though (not having verified my understanding), you grab that adapter, match the holes on the 3212 board to the terminations on the adapter, plug both the badusb and the adapter into your computer, use arduino ide to flash it. But during the entire time you do so, you need to make sure you connect the two silver metallic circles on the upper right side of the TOP of board (this grounds the "firmware flash" pin on the 8266, telling the 8266 that it's supposed to be in fw flashing mode) and hold the white button on the board for the entire duration of the flash. He didn't mention what he used, but I'm assuming it's just the standard nodemcu flasher according to this project's documentation. See if you guys can work it out; if you need more translated details, let me know and I'll give line by line translation. Good luck to all!

So I was able to get the esp flasher uploaded to the arduino with program_pin and enable_pin at the defaults (program: 12 & enable 13). I then connected the two metal circles on the board, pressed the reset button and while still connecting the metal circles, I tried to flash with nodemcu. It looked promising at the beginning but after waiting a few minutes, I gave up and checked the logs. When I hold down the white button, the device turns off so I don't think that part is right. Maybe you need to press it at a specific time?

Logs:

Note:Serial port disconnected.
Warning:Serial port closed by user.
Note:Detect serial port changed.
Note:Auto MAP serial port.Port-->COM7

It's nice to find out, that I'm not only one trying to solve the mystery of this CJMCU-3212 badusb device :-)

Has anyone managed to figure out how to use the default firmware? When I powered the device, it creates WLAN AP with SSID "AI-THINKER_" without password. ESP assigns IP address from 192.168.4.0/24 network but there isn't http server or anything running.

samr28 commented Jun 4, 2018

Mine is the same as @pjaakko. I think we need to figure out how to flash the ESP to get the http server running. From what I understand, to do this, we need to get the leonardo to run the flasher arduino sketch which basically just forwards everything to the ESP board. Then we can put the real arduino sketch on it and we should be good.

I also tried an IP scanner to see if it was just running on a different ip or something but I didn't find anything running so I think the http server is just not running.

Maybe @wilson289296 can re check the video to see what exactly we should be doing for flashing. I tried connecting the two metallic circles but when I press and hold the button (which appears to be a reset button), the device will not turn on. So maybe it was some sort of miscommunication or translation error? I'm not quite sure.

thank you
we are waiting)

I hoped that we can flash esp without any additional adapters.

also I think that we can check number of pins connected to esp and atmega
program_pin and enable_pin

maybe it is not 12/13
can we check with multimeter?

Hi,
Please help to troubleshoot the steps I am using. There seems to be something I am missing.

  1. I have uploaded step1.ino using the Leonardo board. It seems that the program is setting the following pins:
  • ENABLE to high
  • PROGRAM to low
  1. Removed the device from usb socket and soldered wires to the top two right pads so i can easily join and remove the ends of the wires.
  2. Joined the wires and inserted the device into the usb port and ran the command.
    However I am getting the following error message:
esptool.py.exe --trace   --baud 115200 --port COM9 write_flash 0x00000 /dev/esp8266_wifi_duck_4mb.bin --flash_size 4MB --flash_mode dio --flash_freq 40m

I am running this on Windows 10 by the way and will try to run on Mac OS later as the interaction between serial port and esptool might not be working properly. Appreciate any help you might provide in the meanwhile. Thanks.

On the board that I got, the SD card is wired to the atmega32u4 not to the esp8266. this might make it more difficult to move files to it from the 8266.

@kryptonut

It's a great little board. Question, does it just read raw duckyscript in the interpreter, or does it still need an inject.bin of sorts? Might see if I can cobble something together to get the SD card working too - no promises though, I'm not an actual developer.

I've had no success putting scripts on the SD card and from what I've seen in the code, there's no reference to any sort of SD libraries or SD card handling.

Is anybody trying something as this?

Can I flash my arduino code directly?

As I said before the SD is wired to the Atmega, so you upload scripts to esp8266 then send them via serial to Atmega then it has to write to sd

Hi, I was able to make it work! I made a guide for you

https://github.com/puckk/CJMCU-3212

I tried, but not working.

I tried 3 different ways, ending in the same loop. Tried joining the 2 pins as shown in your pic, same issues.

  1. esptool.py --> serial.serialutil.SerialTimeoutException: Write timeout
  2. Arduino IDE --> serial.serialutil.SerialTimeoutException: Write timeout the selected serial port serial.serialutil.SerialTimeoutException: Write timeout does not exist or your board is not connected
  3. NodeMCU Flash --> Waiting MAC

I am not sure, if...

  1. GPIO0 is grounded or not (Or, by default, it is grounded)
  2. Do I need to flash ESP8266 with firmware? Is it a 'must'?

Any suggestions, please?

Now, I tried this video https://www.youtube.com/watch?v=G-Z2rf_AN-c

I followed the steps.

Flash ATMEGA32U4, using Step1.ino file
Flash ESP8266 using esp8266_flasher.exe and esp8266_wifi_duck_4mb.bin as bin file. Held a jumper cable to the 2 circles, pushed it to USB. Connected to the USB. Did not take the cable out. Click on Download on the flasher and uploaded and finally said 'leaving...'
Now, I can connect to the WiFi Duck with password quackquack.

But, I cannot run the script. Nothing happens.

When I checked in the Serial monitor, I saw some wierd characters.

So, in the Step1.ino I changed the baud rate as below:

Serial.begin(115200) --> Junk
Serial.begin(57600) --> Print the commands in Serial Monitor, but nothing gets executed
Serial.begin(9600) --> Nothing happens

Any idea?

Also, even the baud rate is 57600, I can see the output in serial monitor, only when I select 115200 baud. Why is it so?

@cnu77

cnu77 commented Feb 10, 2020

Sorry, its fine now. This is what happens with you do not have any idea about what you are doing.

After spending some time in going through the files that I have, I compared the .ino files I uploaded into ATMEGA32U4 with the actual script from the site, I found that what I uploaded is just a sample script which just prints whatever you send from 192.168.4.1.

Now, I uploaded the correct script and working like a charm.

Has anyone been able to flash the esp8266 via esptool on a mac? The only time I can get it to write anything to the chip is right after pressing the reset button, but as soon as it's done resetting, the esptool quits. I have a lone esp8266 chip that I can write to, but I can't seem to get things to work on this cjmcu board. I found one repo where they were using a modified esptool it looked like, but I couldn't get that to work either. I don't really want to find a windows machine to use the nodemcu flassher tool.
-EDIT
I rewatched puckk's tutorial and he mentions the issues with the esptool and some of the things said in this thread. I'm curious what nodemcu flasher is doing, because it's still using the programmer code of sending the serial data from the arduino uart to the esp uart that we have to install first. And what is this reset button doing that's allowing the esptool to successfully send data? Can we prolong this state somehow, maybe?
I checked all of the voltages at each pin to check that they matched my lone esp8266 chip and everything looked correct. Then I tried to flash the fw directly to the esp in the exact same way I do the lone chip, but that still didn't work. I can see the esp's led flash when using the esptool, but I don't see it flash with the nodemcu flash tool. Anyways, would love to be able to use the esptool if anyone has figured it out.

Did you enable verbose mode to check when it is failing?

I did turn on the trace mode before. I was mistaken - after relooking at the output, it looks like there were some failures when it was trying to write during the reset time. It writes some bytes, reads a byte, which is then declared invalid data. So there does seem to be some communication happening. When it was trying to update the esp8266 without hitting the reset button, the data would attempt to be written, but then timeout while waiting for a packet header.

I did get to a windows box and was able to flash the esp with nodemcu, so I'm able to make some movement working with the device. It would definitely be more ideal if I could get esptool to work so I don't have to jump around workstations.

I skimmed over the nodemcu code and started to get an understanding of how they put it together, but I need to sit down and really peruse through it and figure out what they're doing right. I couldn't even get the esp to flash by directing wiring up to the chip and using esptool, which I thought was strange.

yes.

no, I don't think I'm seeing anything from the ESP bootloader when reset. I've been referring to the output from the esptool via the --trace option, from which I can see the data being written and read (the ack or whatever that is being read is invalid). I hooked up wires to the cjmcu uart pins and could see the hex output of the data written that also shows up in the esptool trace, and don't see anything if I reset the cjmcu board.

Okay, I read everything, but I haven't seen anyone get the ESP-8266 wifi code to upload using the Arduino IDE. I want to do a project similar to Mr. puckk, but I don't want to export as binary then flash it with ESP8266 flasher every time I want to make a change. Has anyone been able to do this or is there a programmer I need to use?

Hello, everyone! Has anyone fixed the issue with CJMCU-3212? To flash it, I used this guide - https://github.com/puckk/CJMCU-3212. After shorting the contacts with a jumper and connecting it to my MacBook, the blue light stopped flashing.
