Problems uploading to ESP32 using arduino 2.3.6

Development Tools Uploading
1

I moved to windows 11 and to arduino 2.3.6 and not able to upload to the ESB32 developmend boards I used I get an esptool.util.UnsupportedCommandError: This command (0x14) is not supported in Secure Download Mode
[PYI-14924:ERROR] Failed to execute script 'esptool' due to unhandled exception!
Failed uploading: uploading error: exit status 1

I do not know this problem and how to solve it!

So what exact Esp32-board you have and do you have something connected to gpio pins?

3

I have several boards in use. Only one I can uploads code from the arduino IDE:

working : esp-wroom-32 on the back site of this developmend board esp32s whith backside

pins not connected

notworking: My own developed board esp32wroom32e not working any more

pins connected

not working: esp- wroom-32 backside esp32 devkit v1 not working all 3 boards

pins not connected

It is working in my windows 10 PC but after switching to an other computer using windows 11 it is not working any more

4

So I wonder from where this comes from:

5

Hai In the end I have tryed several boards using the board manager but that is not helping. What you see is the last tryout

Only one board is working

This is the working developmend board V1

Hi @jnivard.

It is possible for a short or external circuitry connected to the Arduino board to interfere with the upload process, causing this type of upload error.

Make sure the board is not sitting on anything conductive that could short the contacts on the bottom of the board. Make sure there isn't any conductive debris (e.g., loose beads of solder, strands of wire, or component leads) on the board or on the surface the board is sitting on.

If you have a shield or any external circuitry or components connected to your Arduino board, try this experiment:

  1. Disconnect the USB cable of the Arduino board from your computer.
  2. Disconnect any shields, modules, external circuitry, etc. from your board.
  3. Connect the Arduino board to your computer with a USB cable.

Now try uploading a sketch to the board again. Does the upload succeed?

This experiment will determine whether the upload error was caused by interference from your external circuitry. If so, you can then focus your attention on identifying the specific problem with the circuit and resolving it.

Maybe the old working Win10 laptop had plastic chassis... :wink:

10

I have instaled the arduino version 1.8.19 on this windows 11 PC.

In windows I can see when I plug in the USB connector in the developmend board I see the CP210x USB comming up on com8. when I connect a next devboard it is comming up as com9. So the usb ports are recognisched by windows.

When I start the IDE I can see that the com port 8 is disabled. also com port 9 The speed is correctly set 115200

According the IDE the ports are 8 and 9 disabled but in windows all looks ok

11

I'm not sure I understood correctly what you mean by "is disabled". Please provide a more detailed description of what you mean in a reply on this forum topic to help us to understand it.

12

Ok when I start the IDE and open the blink schetch on the bottum line of the serial monitor you see the status one of this status remark is Disabled on com9 or 8 when connected to com8

13

Please make a stronger effort to communicate clearly. Your post is very disorganized and impossible to understand. You might think you are saving time by quickly writing a sloppy reply, but I assure you that it is just the opposite. The forum helpers are often able to provide a solution within a matter of minutes when provided with sufficient information, but we also often see support requests drag out for days or weeks due to ambiguity and confusion caused by ineffective communication.

Are you referring to a "[not connected]" text on the Arduino IDE status bar?:

Yes, in my dutch version it is called disabled.

removing the USB connector in windows I can see the silicon Labs CP210x disapiering. That means Windows is seeing the USB port as active

15

So if you connect the "working board" to usb, windows detects it as CP210x and on IDE you have com port available for it. Selecting Esp32 Dev Module you can upload the sketch.

And if you now disconnect that board and replace it with "non working board", windows detects it as CP210x, but IDE doesn't give any com port available for it?

16

Yes that is the case. two screenshot both icluding the windows CP210 status of com8

This is both arduino 2.3.6 windows 11

I wil repeat it for 1.8.19 windows 11

18

Arduino 1.8.19

The working chip is compiling. The port is in the IDE market as Disabled op com8, but available in windows.

The not working board is compiling but not uploaded. The error message is “board not connected”. The port is in the IDE market as disabled, but you can see it in windows

I see now that you were referring to the Arduino IDE 1.x interface when you wrote this:

You misinterpreted what you saw. Unlike 2.3.6, Arduino IDE 1.8.19 doesn't give any indication of the state of the serial port.

The "disabled" you saw on the Arduino IDE 1.8.19 status bar is the option you have selected from Arduino IDE's Tools > Erase All Flash Before Sketch Upload menu. So it is only telling you about the configuration of the board in Arduino IDE. It is not in any way related to the serial port of the board.

20

Ok thank you for that remark

But the problem I have under windows 11 persist. Only 1 board is working. I will recover my old PC windows 10 and will check ow it is going on that configuration using the existing software and new software

I think now it has to do with the board manger selected configuration and perhaps it need upgrades for windows 11

Thanks for helping

21

Hai

I configured my old PC using windows 10:

1 Arduino EDI version 1.8.13 all my 6 boards are working ok

2-Arduino EDI version 2.3.4 allo my 6 boards are working ok

Moving to Windows 11

1-Arduino EDI version 1.8.19 only 1 developmend board ESPO32S ID:AC7Z-ESP-WROOM32 is working

2Arduino EDI version 2.3.6 only 1 developmend board ESPO32S ID:AC7Z-ESP-WROOM32 is working

3Arduino EDI version 2.3.6 developmend board ID: 2BCLP esp32S is not working

4Arduino EDI version 2.3.6 developmend board ID: 2AC7Z ESPWROOM is not working

5 Arduino EDI version 2.3.6 developmend board ID: 2AC7Z ESP-WROOM-32E is not working id 2AC7Z ESP-WROOM-32E

I have tryed several boards using the board manager but that is not helping
