EMIF Toolkit Fails With Error Message

Description

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

Workaround/Fix

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.
