Critical Issue
This problem affects all external memory interface products.
The EMIF Debug Toolkit may fail with the following error, when linking a project to a device:
Read request of 4 words was sent to the target but only
0 was returned
The workaround for this issue is to not leave the seq_debug
interface
exposed at the top level of your design. Either connect the interface
to an Avalon master, or remove the ports from the top level of your
design.
Alternatively, you could remove the interface completely, by deselecting the Enable On-Chip Debug Toolkit option in the parameter editor.
This issue will be fixed in a future release.
