If CY8KIT-042 is connected - you will see KitProg USB-UART (COMxx) in Device Manager.
This means that you have a COM port on the J8 connector.
Tx: PSoC 5LP P12  (on J8)
Rx: PSoC 5LP P12  (on J8)
Yes I got this to work so that I can flash the board via USB but now I wanna try to get it so it flashes trough the ESP8266 is this possible?
