Have built custom test board using espressif ESP32 IC which was ordered from DIGIKEY. Followed all the hardware design guidelines. But still not able to upload the code. Coming across Packet header failure.
Anyone have faced similar issue as well as anything that I need to look into.

Can you post more info (e.g. schematics and full output of the flashing process) so we can try to help you?

You could try removing the ESP32 from your board and connect it via USB to a PC with the Arduino IDE running on it. Try to upload a simple sketch. I f it still fails you'll know it is probably you IDE setup that is wrong.
(Are you pressing the reset button when the IDE says 'Uploading'?)
