14.1 EDK/SDK - Are there any ECC limitations on the Zynq device DDRx controller?

Description

Are there any ECC limitations on the Zynq device DDRx controller?

Solution

ECC needs 26 bits of DRAM width. How this is allocated is up to the user. However, the most efficient means would probably be 1x 32-bit device.

All of 1x32, 2x16, or 4X8 would work fine.
