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.
