I am getting the fatal error MD5 of file not match data in flash. Below is the output of upload.

I am getting the same error while uploading with esp-idf and Arduino ide or platformio.

How could i solve the issue.

Yes, I have managed to get it working now, the issue encountered was with the strapping pins. Specifically, Pin 45 of ESP32S3 is responsible for configuring VDD_SPI_FLASH. To ensure it operates at 3.3V, the pin should be connected to the ground. Otherwise, it will function at 1.8V, which might cause problems with the Flash functionality.

Fortunately, this can also be resolved by burning some EFUSES using the espefuse.py tool, which comes along with esptool.py. All you need to do is run the command: espefuse.py set_flash_voltage <voltage> (where voltage can be either 3.3V or 1.8V or OFF). For more details, you can visit: link to the official documentation.
