Esp32 not working

Using Arduino Avrdude, stk500, Bootloader issues
1

I have no idea how this happened. I was testing my codes when i thought about changing the delay between the results in the loop so I changed it but it never got uploaded later instead all I saw was this error message which I tried to solve by restarting the application and pc. Maybe I didnt understand the problem quiet well. Can someone tell me a solution to make flash work again in this board?
Error is:

Test a different ESP32

3

try using a lower baudrate 115200 instead of 921600
test with a different USB-cable

4

Are you using a Nano ESP32 or some other ESP32 board ?

5

No it works with another piece and both the boards are ESP32 wroom devkit v4

6

yea did that. Still no luck

7

It does work with another esp. I wanted to know if there is something I can do to make this one work again

Sure there are a lot of things you can do.
If you want straight forward advice you have to provide more information straight forward.

The most important thing that you can do is provide sufficient information by answering questions

The more details you provide at once the more things can be checked at once
If you prefer short-messaging the result will be a looooong time taking thread.

Did you try with a different USB-Cable?
Provinding sufficient information is to write down more words than just
"Yes I did"
write "Yes I tried with another USB-cable" the result is:_________________

What exact board have you chosen in the Arduino IDE? Post a screenshot of your Arduino-IDE

Post a picture of the "not working" ESP32

For posting pictures you have to do a few things that are easy to do
You have to reach trustlevel 1 through these activities:

Get to trust level 1 by…

  • clicking on 5 different threads
  • reading 30 postings (they must have been visible on the screen
  • beeing a minimum time of 10 minutes in the forum

adjust the Arduino-IDE to print out most verbose details about the upload-process by like shown in this tutorial

I moved your topic to a more appropriate forum category @tirthkamdar.

The Nano ESP32 category you chose is only used for discussions directly related to the Arduino Nano ESP32 board.

In the future, please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.

Thanks in advance for your cooperation.

If you want to deep dive into it: get a suitable JTAG adapter, OpenODC and read the docs JTAG Debugging - ESP32 - — ESP-IDF Programming Guide latest documentation
