This appendix catalogs revisions to the Stratix IV GX FPGA development board.
lists the versions of all releases of the Stratix IV GX FPGA development
board.
Single-Die Flash Version Differences
The single-die flash version of the Stratix IV 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 considered 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 U32. The single-die package is smaller than the dual-die version.
