DisplayPort 1.4 TX/RX Subsystem - 2018.3 - ZCU102 Example Design Application fails to build in SDK with "undefined reference" errors

Description

When I try to generate the DisplayPort 1.4 TX-only/RX-only example application for a Zynq UltraScale+ MPSoC ZCU102 Evaluation Kit, the build fails with the following errors:

undefined reference to `__abort_stack' boot.S /standalone_bsp_0/psu_cortexr5_0/libsrc/standalone_v6_8/src line 160 C/C++ Problem
undefined reference to `__fiq_stack' boot.S /standalone_bsp_0/psu_cortexr5_0/libsrc/standalone_v6_8/src line 173 C/C++ Problem

Why do I get these errors and how can I solve this?

Solution

In 2018.3, the DisplayPort 1.4 TX-only/RX-only example applications for the ZCU102 board have been moved to the A53 processor. 

For this reason, the linker script inside the example is targeting the A53. This will cause an issue if the user targets the application for A53.

The solution is to import the DisplayPort 1.4 TX-only/RX-only example applications for the ZCU102 board from a BSP targeting an A53 processor.
