Minimal Hardware for bare ESP-WROOM-32

[kevinmohu]

I would like to know if I can upload code in my bare ESP-WROOM-32 with a minimal hardware.

I'm using an FTDI with TX, RX, and GND pins (not RTS and CTS pins), I found documentation about this, indeed, that's possible, I had success, but you have to add two buttons for pointing the sequence has started.

My goal isn't to add these two buttons, I need to reduce my hardware, only with the FTDI. Is it possible to do this by modifying configuration files?

Thanks.
