    • Expansion Connectors • LCD Interface with Touch Screen Support Note: The EDB9315A kit does not include a LCD screen. The LCD interface is pin-compatible with previous Cirrus Logic development boards. Not all features of the EP9315 are on the base board. Two high-density connectors have been provided to allow for daughter card expansion.

    One item not listed above is the Flash device. It is located on the bottom side of the board, under item C. There are no jumpers on the board. The only "jumper" is the serial boot pushbutton. This button is used when the developer wants to use the Cirrus Logic download utility to put new code into Flash memory. ©...

    The “Serial Boot” pushbutton, S2, is used to configure the board to perform a serial boot. A serial boot is used to program the Flash device with the Cirrus Logic download utility. Instead of using jumpers, a pushbutton is used. Simply hold the pushbutton down while pressing and releasing the reset pushbutton, S3.
