remote proc error -22 on startup. Possibly a device tree error?

I am right now trying to get remoteproc working on the UG1186 (v2020.1) guide. I am using petalinux 2020.1 and Vitis 2020.1. I am assuming that there is an error with a linker or device tree somewhere. When I look at older versions of the UG1186 guide, I find reference to something in the device tree about the elf_ddr_0. I am unsure if this was removed on purpose or if I need to re-add this to the device tree and there is an error on UG1186: 

 

amba {
elf_ddr_0: ddr@0 {
compatible = "mmio-sram";
reg = <0x3e000000 0x400000>;
};
};

 

 

All of the guides and answers that I find for this issue don't seem to fix the issue I am having. I have looked at https://forums.xilinx.com/t5/OpenAMP/Libmetal-AMP-Demo-fails-to-link/td-p/891623 as a large help to get started, but unfortunately it seems that a large portion of it is outdated.

 

For my debugging steps here is the following:

HI @victorwiedemann 

Please use the device tree changes suggested in ug1186 (2020.1) guide. Device tree changes are different for older versions.

 

Thanks & regards
