@burudsandeep Hi, here are a few steps you can try:

• Check USB Connection – Make sure you are using a reliable data-capable USB cable (not just a charging cable), and connect the board directly to your computer’s USB port (avoid hubs if possible).

• Put the board in download mode – Hold down the BOOT button while pressing RESET, then release RESET while still holding BOOT. This forces the device into download mode so it can accept new firmware.

• Command line (alternative)
  If you prefer, you can flash using esptool.py. For example:

esptool.py --chip esp32s3 --port COMx --baud 460800 write_flash -z 0x0 firmware.bin
Replace COMx with the correct port from your system and firmware.bin with your firmware file.

If you still have issues after trying these steps, please share what errors you’re seeing in VS Code or Espressif IDE, and we can guide you further.

Hi ESP-Mars, could you please share your email ID or any contact information so I can connect with you? That would help me explain my problem more clearly.

The error I encounter keeps changing each time. For instance, right now I'm seeing this error:
" C:/Espressif/frameworks/esp-idf-v5.3.1/components/freertos/app_startup.c:206:(.text.main_task+0xa8): undefined reference to `app_main' "

I want to confirm that you're experiencing a compilation issue not flash?
Could you please post the completed compilation log?
