Development Tools Uploading

Hi mates ! I can't upload the code on ESP32 (which was previously working fine). It gives this error:

I've tried changing the port and also pressing the boot button (previously it didn't require pressing it) but in vain. Please suggest any solutions.

Does anything appear in the serial monitor after you press the reset button ?

3

NO, nothing shows

Take a look here --> https://forum.arduino.cc/t/solved-esp32-s3-cannot-upload-the-sketch/1058691

and here --> https://forum.arduino.cc/t/solved-esp32-problem-with-sketch-upload/1033894/5

for some possible situations.

If your board has a "boot" button, are you holding it when "Connecting.............." appears?

Thanks, but I've tried pressing boot. It doesn't work, rather board turns hot after being plugged in

6

Press and hold reset.

Press and hold boot.

Release reset.

When you see Connecting . . . . - . . . . - , release boot.

7

No experience with your board but that sounds very unhealthy. Which component(s)? Anything connected to the board? If yes, schematic diagram / wiring diagram will help others to help you.

8

Magic smoke being released ?

9

How you are powering with Battery or with Port

10

Port

11

Port Through power bank or through PC / laptop

the board's chip was burnt. I bought a new one it works fine
