Two chips, one Biscuit — flash them in any order.
Keep the same USB cable connected. In the browser dialog, select
either serial interface: we detect which chip it is and flash that
half, then prompt you to select the other. The C5 appears as
“USB JTAG/serial debug unit”, the WROOM as
“USB Serial (CP210x/CH340)”.

Working…
First try: leave the Biscuit powered on and click Connect & Flash. No button sequence is normally needed. If it won't connect, hold BOOT, tap RESET, release BOOT, then try again.
