I don't use burst on the NIOS II, neither on the Clock crossing bridge (which is between the NIOS and the DDR2 SDRAM controller).

However I can see "Memory Burst Length = 4" In the parameter of the MT47H16M16BG-5E in sopc builder.

I attach the DDR2 parameter that I entered.

To create this preset, I took the "Micron MT47H16M16BG-37E" preset which is include in the list preset as default and I change the "CAS Latency" from 4 to 3".

Did I make mistake ?
