If you are executing these steps, then OpenAMP loader isn't used at all if I understand correctly.
Instead it's elf loader in linux kernel.
Here: https://github.com/torvalds/linux/blob/v6.10-rc2/drivers/remoteproc/remotep…
As of now, on Xilinx platform C++ loading isn't tested.
Thanks.
Yes this one is failing I think.

We are COMPRION GmbH from Germany, and we are using the Xilinx FPGA ZynqMP XCZU3EG for our new testing-devices.
I'am an embedded engineer, with the responsibillity to program the ZynqMP Linux and R5 Progs.
Currently I've the problem, that a load of a c++ program via remoteproc doesnot work in the xilinx petalinux.
Maybe there is someone how can help me out....
We are working with the petalinux 2021.2 release.
I've tested the new 2024.1 release, but there are no changes to the issue.
The c++ prog. doesnot load.
I've searched the openAMP github for such issues, and I found this one:
https://github.com/OpenAMP/open-amp/issues/27
which has been closed in 2018.
My question is now: How to get these things in the xilinx branch, or is there a branch which has been fixed this issue?
Thank you in advance.
