General PLD Information
|PLD Update Instructions|
VersaLogic CPU boards feature one or more programmable logic devices (PLDs) that control various functions of the board. PLDs are factory programmed and may, on certain boards, be re-programmed with updated code in the field. Updating to the latest PLD code might improve performance or correct errors. To update PLD code, you must download the file that contains the code and the update utility, ISPDAT.exe. You must run the utility from DOS, not a DOS window.
|Note: On some VersaLogic SBCs, such as the EBX-22, the PLD version is contained in a special register; see the reference manual for details. See the support page for your board for PLD and BIOS compatibility information.|
Before you update the PLD code of your VersaLogic SBC board, make sure you do the following:
ispdat -board SBC -aprogram dat_fileWhere SBC is the VersaLogic SBC model and dat_file is the DOS-renamed DAT file. For example:
ispdat -board ebx-22 -aprogram PEBX22~1.datNote that the process takes about two minutes and should not be interrupted. A pass or fail message is displayed when the process is complete. If the process fails, call VersaLogic Customer Support at (800) 824-3163 for assistance.
Note: When programming multiple boards in a version-controlled opereration, you may speed up programming by using the -nv (no verify) option. This option is available only with ISPDAT.exe version 1.01 and later.
The ISPDAT utility writes new PLD code to the on-board PLD. The utility is included in the PLD download files on the support page for your board, but you can download it separately below.
ISPDAT Utility rev 1.07
This utility writes new PLD code to the on-board PLD.
