I am new to this and wondered how do you load the firmware to the esp32? Can someone smart enough to tell me??

Hi and welcome.

To load firmware: right-click->Load firmware

It must be a bin file 4 MiB in size.

So the code has to be compiled to load it?

Yes, you must compile the code an upload the binary.

Ok but the esp32 is saying that the core dump flash config is corrupted and it won't boot up

Hi.

It is much better if you copy/paste the whole error message here.
Or even the whole output of running the circuit.

But the best is sharing your circuit, source code and firmware.
This way I can reproduce the exact problem.

Also, how did you compile the code?
