[dekeoma]

esptool.py v4.6
Serial port COM3
Connecting......................................

A fatal error occurred: Failed to connect to ESP32: No serial data received.
For troubleshooting steps visit: https://docs.espressif.com/projects/esp ... oting.html
while i am worried is that it was working some minutes ago andi was connected, all of a sudden it stopped
the esp32 isn't showing any visible burn or fault, and it is lighting up perfectly fine, it is also being detected by my ardunio IDE, i have tried all trouble shooting methods on youtube, but to no avail it isnt even flashing..
what can i do??

[ESP_Sprite]

What hardware are you using? If your board has a boot button, can you try holding that while unplugging and replugging your board, then reprogramming?

You can try the option ESP_Sprite mentioned above, and if that doesn't yield a result you can also format the ESP32 using the method in the link below, and then reupload the code.

Hope that helps.
