Nios II-Based Sequencer for RLDRAM II Requires a Burst Length of 8

Description

This problem affects RLDRAM II products.

The Nios II-based sequencer used with the RLDRAM II external memory IP requires a burst length value of 8. When using the Nios II sequencer, you must not configure the RLDRAM II devices in configuration mode 1 or configuration mode 2, because these modes do not support burst length 8.

Workaround/Fix

The workaround for this issue is to use the RTL-based sequencer when using configuration modes 1 or 2, because the RTL-based sequencer supports all RLDRAM II burst length values.

This issue will be fixed in a future release.
