SDK 2014.4 - ERROR: [Hsi 55-1464] Hardware instance __EMPTY__ not found in the design

Description

In my Zynq IPI design using AXI-APB bridge, the MI port of the APB bridge was made external.
 
After I export hardware to SDK, the following error occurs when creating the BSP.
 
ERROR: [Hsi 55-1464] Hardware instance __EMPTY__ not found in the design
ERROR: [Hsi 55-1464] Hardware instance __EMPTY__ not found in the design
ERROR: [Common 17-39] 'hsi::create_sw_design' failed due to earlier errors.

Solution

This is a known issue in Hardware export when an external port is created.
 
In the HWH file, you can see that the APB related instance was set to _EMPTY_.

This issue is fixed in the 2015.1 release.

A patch is attached for Vivado 2014.4.

To use the patch, extract the zip file and assign a MYVIVADO environment variable with the path to and including the vivado\ directory.
