A. Board Revision History

This appendix catalogs revisions to the Arria II GX FPGA development board.

Table A–1 lists the versions of all releases of the Arria II GX FPGA development

board.

Single-Die Flash Version Differences

The single-die flash version of the Arria II GX FPGA development board is created to

replace the obsolete dual-die flash device with a single-die flash device. The two flash

devices are equivalent except for some software routines used to access them because

the single-die device has only one CFI table whereas the duel-die device has two CFI

tables.

To determine which flash your board is using, refer to the device part number

installed at U23. The single-die package is smaller than the dual-die version.

f For more information about the flash change and its application, refer to the Arria II

GX FPGA Development Kit User Guide.
