6.3 Data2MEM, iMPACT - An error appears in the status register; the CRC Error bit is NOT 0 for Virtex-4 devices


General Description:

When I run Data2MEM on the command line, an incorrect ID code is written in the BIT file for all Virtex-4 devices. (Direct BIT file replacement of the BRAM contents is not supported for all Virtex-4 devices.)


You can work around this issue as follows:

1. Add the BMM and ELF/MEM file to the ISE project.

2. Run Project -> Cleanup Project Files in ISE.

3. Run the Generate Programming File in ISE.

This will properly update the BIT file with the ELF/MEM contents.
