4.1i HW-130 CoolRunner Hprep6 - A JEDEC file checksum error occurs on XPLA3 JEDEC or Readback JEDEC


Keywords: HW-130, XPLA3, JEDEC, Hprep6, File Checksum, Readback

Urgency: Hot

General Description:
CoolRunner XPLA3 JEDEC files produced by 4.1i used an incorrect method of generating the file checksum. When this JEDEC is loaded into the HW-130 v5.0 (or other third-party programmers), an error message reports the file checksum error. (Previous versions of JEDEC files produced by WebPACK 3.3 work properly.)

This error can also occur for JEDEC files that are produced using Readback from iMPACT.


There are three possible causes of this problem:

1. A bug existed in the JEDEC file as it was created by the 4.1i and 4.2i software.

This problem is fixed in the latest 4.2i Service Pack, available at:
The first service pack containing the fix is 4.2i Service Pack 1.

2. A bug in the HW-130 software prevented the tools from properly parsing the JEDEC file.

This problem is fixed in the HW-130 programming software as of version 5.01.

3. This problem may also appear if you are not using English US regional settings.
