Failed to execute script esptool the selected serial port Failed to execute script esptool does not exist or your board is not connected #1137

I tried that, nothing worked. |
|
I am guessing you are on Windows????
And last, some ESP32 boards need to be set manually into bootloader mode. On my board that would be pressing the RESET button and keep it hold, then press the USR button and keep it hold, then release the RESET button, then release the USR button. Might be different for your board. |
|
Thank you,,, Issue Solved |
|
Glad I could help. |
|
Also, if you working on a laptop, make sure it is on full performance and plugged in. |
|
Holding down the "Boot" button on my ESP-WROOM-32 while the Arduino IDE download the program worked. After the download I had to push the "EN" button to run the program. It did NOT start on it's own. |
|
Hey, anyone here? I have a similar issue but unlike this one, I can select my COM Port and the drivers are also up to date. However, what I am finding out of place is that in the COM Port list I am getting some 17 options for COM1 even though nothing else is connected to the laptop. Any ideas? |
you can get those COM port options in Device Manager |
|
push the "BOOT" button worked! Thx guys. |
|
Worked after changing my USB cable |
|
Hey anyone here? I get the error message saying that the selected serial port Failed to execute esptool does not exist or your board is not connected. I also installed the CP210x USB to UART Bridge VCP Drivers as well. Hope someone help me with this.. Thanks |

Did you select the proper serial port & speed? perhaps lower the speed to 115 or 230kbps |
|
Hey
When I go to device manager it does not show any port. Is that mean I have
to change the USB cable..?

when I program it using the FTDI module I cannot select a port then I

1. Make sure you have a good cable
2. Enter download mode manually by resetting the board while the boot
button is pressed.

Hey guys. I was getting this error and my work around was changing the "Flash Mode" from "QIO" to "DIO". |
Hello, i have a ESP32-WROOM-32 and your Tip was the Solution for me. unplug the Device, hold Boot button and plug device, further hold boot button and Upload Firmware. |
|
One other solution I found today not mentioned above that might help others. Insufficient power from the computers (Microsoft Surface Pro 6 in my case) USB port caused exactly the same issue, even though when plugging in directly, the device was fully recognised in device manager and showing up as COM3 in my case. I knew the cable was good as I was able to flash firmware from a desktop machine. Resolved by using either an externally powered USB hub, or a Surface docking station which among other things is also an externally powered USB hub. Note I also did upgrade the driver using the My ESP32 board is an AITrip ESP32-WROOM32D. Arduino IDE settings are (reading the bottom right of the IDE) Hope that helps someone 😄 |

I'm having same issue and I've tried all the above steps except externally powering it, its showing up in COMPORT and everything but keeps giving me this error: - (it works on my friends pc but not on my laptop please help) File "esptool.py", line 4582, in |
see into manage device, look at the port com and select the port number you use, click on this, open the settings and configurate "port configuration" and change bits per seconds |
|
i try to change my port in device manager, and it's worked |
|
I was using the wrong port as well! It stayed on "Connecting..." while compiling before the timeout error. It worked once I switched to the correct port. |
|
Unplugging and plugging in the ESP32 worked for me, surprisingly |
and others
