DQS# Enable Option Must be Enabled for LPDDR2 Interfaces


This problem affects LPDDR2 products.

The LPDDR2 interface supports only differential DQS signals. The DQS# Enable option on the Memory Parameters tab in the parameter editor must be enabled.


The workaround for this issue is to ensure that you always enable the DQS# Enable option for LPDDR2 interfaces.

This issue will be fixed in a future version.
