I am trying to upload the a simple program to my HMI 5" display following the first example I did all the required changes and settings but I am always getting:
A fatal error occurred: Unable to verify flash chip connection (No serial data received.).
Failed uploading: uploading error: exit status 2
I tried all possible solution even I tried using different sequences of boot and rst buttons which gives me "waiting for download message" but still giving me the same error.
also I tried changing the version of the esp32 board versions going from 2.0.14 till 3.0.4 and all of them are giving me the same error.

Hi @ahmedsamy
May I ask which version of your hardware board it is?

Please troubleshoot the issue through the following methods:

Replace USB cable
Check if the USB driver is installed
Check if the settings are correct(please refer to: https://www.elecrow.com/wiki/ESP32_Display_5.0-inch_HMI_Arduino_Tutorial.html#upload-the-code)
Follow this guide to upload firmware to check if there are any issues with serial port
