The other three fields that we have to edit are the “FLASH SIZE” of the ESP8266 board, the “COM
PORT” of the serial cable and the communication's “BAUDRATE”. The flash size of Olimex boards
is 2MB = 16Mbit and it is suggested to use the 16Mbit-C1 option. The “BAUDRATE” is 57600. The
“COM PORT” is different depending on the system. The serial cable here gets assigned COM3 so
that is what we would assign. Refer to the “Windows Device Manager” to find the COM port
number of the cable of your system.

At this point make sure that the ESP8266 board is in UART (bootloader) mode as suggested in
point 1. We also need to have the serial cable connected to the RX, TX and GND signals of the
board.
