I have installed esptool. I would like to know what command to type to erase esp32 s3 flash.

I have not used it, so this is not from esptool experience, but isn't part of the answer in your screenshot? If you read backward from the bottom, the white text tells you what the issue is, and you can see what folder you're in on the last white line.

The darker coloured text indicates the actual path which may contain the esptool.py file. Also, there's a recommendation there to add it to your path (just click on the Windows icon and type 'environment variables' in the Windows search box to find that.

I don't know weather that is the right way to erase the esp32 flash. I am looking for someone who know which exact tool to use in order to erase the flash. An expert who have done it many times and knows the nitegrity of the tools and its working.

"I don't know weather that is the right way to erase the esp32 flash."

All I'm saying is that your screenshot is definitely the wrong way. If you're trying that, then you should be trying it in the folder where you actually installed the file (or add to your path and re-open a command prompt).

ok, appreciate you response. Still looking for an expert to help me out in a right way.

Why do you want to call it manually?
I mean, I'm only ever using it inside VSCode with the PlatformIO extension that takes care of all that tedious setup.

I've used the esptool for the ESP8266 NodeMCU downloading esptool from github https://github.com/espressif/esptool

Troubleshooting - ESP32 - — esptool.py latest documentation (espressif.com)

I wrote a blog, look for NodeMCU Firmware at NodeMCU Amica V2 road test - Hackster.io

Don't know exactly what you want to do. Do you need a bootloader?

I checked my notes, and even from the command prompt, I've never needed to run esptool.py either. From the command line, idf.py is used to handle Flash erase and programming steps.

After a pip install it should just work...

1. You are using Linux style USB port identification (dev/ttyUSBx) instead of windows based identification (COMx)

2. Esptool.py is not added to the path as you have just installed it in local user data, which system can't access unless you add the path to environment variables.

3. You can actually use an executable named "esptool.exe" that is automatically installed when you install esp32 package automatically. Install "everything" software to find the location of that application and open a cmd window from there. Enter "esptool erase_flash", application will automatically scan all USB port and erase the flash memory of esp32 (assuming it is in boot mode).

Yes I need to upload a boot loader of micro python in esp32 s3 sense
