Zynq UltraScale+ MPSoC, Vivado 2017.3 - PS DDR Does not work correctly in hardware, but did work in Vivado 2017.2 and earlier

Description

In Vivado 2017.3, My PS DDR does not work correctly in hardware.

However, it did work in Vivado 2017.2 and earlier.

Solution

This can occur because the PS DDR component data width parameter of the Processing System IP GUI is not correctly updated.

This leads to incorrect settings in the PS DDR initialization script, potentially leading to hardware failures.

A patch is attached below to correct the issue in Vivado 2017.3 and 2017.3.1.

This issue will be fixed starting with Vivado 2017.4.
