Configure the
Development
Board
The EPXA1 device can be configured by a variety of different methods.
The configuration process involves setting up the embedded stripe
registers and the on-chip SRAM in order to boot, in addition to initializing
the PLD array. The processor boots from address 0H; there are two ways
to make code available at this address: boot-from- passive-serial or boot-
from-flash.
Boot-from-Passive-Serial Mode
The BOOT_FLASH pin is tied high on the EPXA1 development board, but
boot_from_serial configuration is still possible using the Quartus II
programmer. This is because JTAG configuration overrides other modes
of configuration. For information on configuring the EPXA1 device using
the Quartus II programmer, see the Quartus II on-line help.
