Xilinx Vivado 2019.2Xilinx Vitis 2019.2
The option for OpenAmp library in the CortexA53 core is missing in Vivado 2019.2 and in the update.
With the CortexR5 the OpenAmp library works well.
The option for select 64bits and 32bits is missing too.
For A53, sysroot is used for libraries.
If you have a petalinux project, you will need to include the library in your rootfs
Enable the OpenAMP and libmetal packages with "petalinux-config -c rootfs":
Filesystem Packages --->
Build sdk and package sysroot
Your sysroot will be located here sysroot=/<plnx-proj-root>/images/linux/sdk/sysroots/aarch64-xilinx-linux
You will need to include the sysroot path in your Vitis application for A53
