@kernelchuk ,
I'm trying to funderstand what is mandatory and not for AMD project.

Could you clarify the need of this examples for AMD?

By essence the libmetal is used to adapt the openamp lib to the target ( compiler, platform, OS). Do you have some project using only lib metal?

So i wonder if this code is only for legacy and what you really need is just open-amp examples running on AMD platforms (#19)

@arnopo,
The libmetal example - zynqmp_amp_demo is used in our Vitis tool as described in https://docs.xilinx.com/r/en-US/ug1186-zynq-openamp-gsg/Xilinx-Libmetal-AMP-Demo

Other projects at AMD use libmetal without OpenAMP. From the top of my head: RFDC. We also use it internally for testing and validation. This is not legacy code.
