Lesson 7 Erasing ESP32 Flash Memory

In this lesson I will show you how to erase the flash memory inside ESP32. Before flashing the MicroPython firmware, you need to erase the ESP32 flash memory. So, with your ESP32 connected to your computer, hold-down the “BOOT/FLASH” button in your ESP32 board:

While holding down the “BOOT/FLASH” button, run the following command to erase the ESP32 flash memory:

When the “Erasing” process begins, you can release the “BOOT/FLASH” button. After a few seconds, the ESP32 flash memory will be erased.

I'm getting the below error. Ctrl+C didn't work. restarting also didn't work. Can you tell about the bootloader mode specific for esp32 Cam module and mention names of Buttons to use for boot process.

Device is busy or does not respond. Your options:

- wait until it completes current work;
- use Ctrl+C to interrupt current work;
- reset the device and try again;
- check connection properties;
- make sure the device has suitable MicroPython / CircuitPython / firmware;
- make sure the device is not in bootloader mode.

Should I have the esp32py tool if I am working in the Arduino IDE?

[danielp]

On my esp32 and all others that I have seen, the boot button is on right side whereas your buttons are backwards… is it a special version?

[NoBRC]

Has anyone an idea: I have two identical esp32 wroom boards but one is saying „xmc flash memory wasn’t detected“ while programming it.

By pressing enter by holding boot button it shows nothing again the command prompt comes what did i do

[kitlinghou]

I tried to execute your cmd above but it shows "WARNING: Failed to communicate with the flash chip, read/write operations will fail.", may i know what wrong in my esp32 chip ?

I bought a new esp32 and I'm not able to erase.It is configured on COM5 port and show this message:
COM5 failed to connect: could not open port 'COM5': PermissionError(13, 'Acesso negado.', None, 5)

don't we need python installed for this?

Will the bootloader also get erased after erasing flash? I am asking this that people say say to erase flash if u are going to use micropython. What if I want to use Arduino IDE only?

[Creepy_Chronicles-nt]

Can you please make a video for erasing flash memory of esp32 cam module ?

[daulatram]

do u accept challenge? how to reprogram esp32 camera module by erasing memory

[awikwik]
