removing Espruino from an ESP-Wroom

I bought this board:

https://it.aliexpress.com/item/32840815594.html?aff_platform=product&sk=MrbMVr7&aff_trace_key=2602152a965e4e4d8846346a10315a9d-1588781756776-07769-MrbMVr7&terminal_id=f41591a4ef0f48ddbf83603216e7dd45&aff_request_id=2602152a965e4e4d8846346a10315a9d-1588781756776-07769-MrbMVr7

And flashed the espruino_esp32.bin according to the instruction posted here: https://photopizza.org/#!instructions

Now I want to use this board for a different project with Arduino IDE. I got some troubles with simple web server tutorials such as this: https://randomnerdtutorials.com/esp32-web-server-arduino-ide/

I manage to upload sketches and to see the board in AP mode, but not in STA mode.

I'm a newbie, I guess the ESP32 has several partition, and I wonder if there's the way to put it back in factory condition, since the changes I made could be the problem's source.

thanks for the help

Francesco

use esptoo.py with erase flash

I used this twice:
esptool.py --chip esp32 erase_flash

But still can't see it as a STA in my network. I thought this command was not enough for erasing the bootloader.

Now the ESP32 is clean, without any firmware, next is to install the firmware you like to run.

Hello @user112232 !

Could you tell me and explain to me how you managed to compile/flash PhotoPizza on your controller please?

I would like to do this project myself and it has been about two weeks since trying to compile and flash "Photopizza" on my ESP32 but I am unable to do !

your help would be very valuable for me and for all users wishing to do this project too.

Hi there, I just followed the instructions here:

https://photopizza.org/#!instructions

And I remember I had to install Python and flash the ESP32 from it.

Hi @user112232 , thank you for this reply !

This does not help me much because I have already tried several times to follow these instructions (which are incomplete) but without success!

Could you tell me how you followed the steps to upload files?

Which way did you upload the first file:

With "RAM" mode, "Flash" mode or "Storage" mode?

And how did you upload the second file:

With "RAM" mode, "Flash" mode or "Storage" mode?

Does the "PhotoPizza" network appear in your home after uploading the files?

Also, do you remember which Espruino Firmware you managed to get the whole thing to work with?

Sorry,
it was months ago.
I succeded flashing and operating it, but then the prototype was left in a corner.
I remember it was not immediate, and I troubleshooted somewhere, but unfortunately I did not took notes of it.

I can only suggest to look for solution for this specific case.

best wishes
