I have followed your approach and left programmed plugged in and pressed reset button. These are the messages I am getting(*attaching photo). What can we make of this? To my understanding the chip is in SPI boot mode. It is not expecting more download commands. Any ideas?

What particular ESP32S3-Wroom1 module do you have (Should be a number/letter combo like 'F8R8' on the shield somewhere.) Asking because if it has octal flash, you need to setup your platformio project to use that and also possibly
this is applicable.

FCC ID:2AC7Z-ESPS3WROOM1
IC:21098-ESPS3WROOM1
That is all I am getting from the chip. I have ordered this particular esp chip from electronics shop, in their website the chip is named ESP32-S3-WROOM-1-N16.

Just to check if it's not a software error, could you use esptool to write the attached bin file? (esptool.py write_flash 0 hello_world_merged.bin)

Do I need MicroPython for this?

Quick update. I have borrowed the USBdetector from my friend and tried to look how much current I am supplying during the flashing process. Current readings show absolute zero(attaching photo). Could this still be hardware related issue? Maybe my usb power supply cable is damaged?
