AR# 60206

描述

In my design, I associate an ELF File to my project, then run Implementation. 

After Implementation completes, I remove the ELF files from the project and then run write_bitstream.

After downloading the Bitstream on the FPGA, I see that the previously associated ELF File data is included in the bitstream.

The bitstream report also reports the association of the file.

I get the following message when I run write_bitstream after removing the ELF files from the Design Sources.

INFO: [Memdata 28-144] Successfully populated the BRAM INIT strings from the following elf files: ../hi.elf

解决方案

This Behavior is incorrect since the write_bitstream operation should take the default bootloop file if no elf files are associated.

The Work around is to re-run Implementation after removing the ELF File. 

Associating a different ELF File also works during write_bitstream.

However, the default Bootloop association does not take place during write_bitstream in this case.

This issue is fixed in Vivado version 2014.2.
