For information about board-supported FPGA configuration schemes,
refer to

Table 2–7 on page 2–15

.

Table 2–6

shows configuration file sizes for board-supported Stratix II GX

devices.

1

The 512-MB, on-board flash device is able to store either eight
designs of the EP2SGX90 device plus 32-Mbytes of additional
files, or eight designs of the EP2SGX130 device and 16-Mbytes of
additional files.

Table 2–7

shows the board-supported FPGA configuration schemes.

The same DIP switch used to select the configuration mode will
also have RUnLU pin control as well as some JTAG chain options.
Refer to the

“General User Interfaces” on page 2–21

for more

information on the DIP switch.
