Power In Header (P12)
The P12 header supplies the power to the on board 1.2V and the 2.5V reg-
ulators. The 
P42 and P43 headers supply the power to the external 1.2V 
and 2.5V planes, as described in “2.5V Header (P42)” and “1.2V Header 
(P43)” on page 2-10.

Jumpers
Before using the Blackfin FPGA EZ-Extender, follow the steps in “FPGA 
EZ-Extender Setup” on page 1-1.
Figure 2-3 shows the locations of all jumper headers. A two-pin jumper 
can be placed on the respective jumper header for different functionality. 
The following sections describe all possible jumper settings and associated 
functionality.

Jumpers
2-12 Blackfin FPGA EZ-Extender Manual
Serial ROM Boot Jumper (JP1)
By default, the serial ROM boot jumper, JP1, is unpopulated. When 
unpopulated, the FPGA EZ-Extender programs via the Blackfin processor 
or the Xilinx JTAG header.
When 
JP1 is left populated, the jumper connects the serial ROM chip 
enable pin to the done bit of the FPGA. At power-up, the done bit is 
driven 
low by the FPGA, causing the FPGA to enable the serial ROM as a 
programming source. After the FPGA is programmed, the...

Table 2-11 summarizes the jumper settings.
Config Program Jumper (JP3)
The configuration program jumper, JP3, connects the program bit of the 
FPGA to the Blackfin processor’s flag pin. By default, 
JP3 is populated. 
The jumper assures that the program bit is asserted by the Blackfin proces-
sor to initiate the FPGA programming through development software.
Table 2-12 summarizes the jumper settings.
Boot Jumper (JP4)
The boot...

2-14 Blackfin FPGA EZ-Extender ManualTable 2-13 summarizes the jumper settings. See Table 2-3 on page 2-5 for 
the JTAG header boot settings, Table 2-5 on page 2-6 for the serial ROM 
boot settings, and Table 2-7 on page 2-7 for the Blackfin processor boot 
settings.
FPGA Input Jumpers (JP5)
The FPGA input jumpers, JP5.2–5.8, drive select FPGA nets to a logic 0 
and can be used for any user logic that requires a steady state input. You 
can set internal pull-ups on these nets in the FPGA and,...

Push Buttons and LEDs
Before using the Blackfin FPGA EZ-Extender, follow the steps in “FPGA 
EZ-Extender Setup” on page 1-1. 
Figure 2-4 shows the locations of all push buttons and LEDs. The follow-
ing sections describe the associated functionality of all the push buttons 
and LEDs.

Push Buttons and LEDs
2-16 Blackfin FPGA EZ-Extender Manual
Program Push Button (SW1)
The program push button, SW1, erases the contents of the FPGA. The 
push button can be used as a hard reset—the FPGA must be completely 
re-programmed once 
SW1 is de-pressed. See “Programming the FPGA” on 
page 2-3 for more information.
PB1 Push Button (SW3)
The PB1 push button, SW3, is a general-purpose input push button. The 
switch with a connected debounce circuit eliminates the need to re-create 
it in the FPGA....

Power LED (LED9)
The power LED, LED9, connects to the 2.5V power supply and, when lit, 
signifies that the FPGA EZ-Extender is powered properly.
Done LED (LED10)
The done LED, LED10, connects to the done pin of the FPGA. At 
power-up, the FPGA is blank and needs to be programmed. When lit, the 
LED indicates that the FPGA is programmed successfully.
