While executing "./host_ps_on_x86 a.xclbin", I am getting the error.

Description

Continuing from my previous ISSUE (https://github.com/Xilinx/xup_aie_training/issues/12), I am getting this error after modifying host.cpp file. After going through host.cpp file, I found that it is not using AIEngine when invoked to run on hardware. I added some changes (lines 98 to 109) as shown below :

    // Execute the compute units
 93     std::cout << "Run the kernels" << std::endl;
 94     auto run_pl_s2mm_1 = pl_s2mm_1(out_buff_1, nullptr, num_elements);
 95     auto run_pl_mm2s_1 = pl_mm2s_1(in_buff_1, nullptr, num_elements);
 96     auto run_pl_mm2s_2 = pl_mm2s_2(in_buff_2, nullptr, num_elements);
 97  
 98 //////////////////////////////////////////
 99 // graph execution for AIE
100 //////////////////////////////////////////      
101
102     std::cout << "graph init\n"<< std::endl;
103     vadd_graph.init();
104
105     std::cout << "graph run\n" << std::endl;
106     vadd_graph.run(1);
107
108     vadd_graph.end();
109     std::cout << "graph end\n" << std::endl;
110
111     // Wait for kernels to complete
112     run_pl_mm2s_1.wait();
113     std::cout << "pl_mm2s_1 completed" << std::endl;
114     run_pl_mm2s_2.wait();
115     std::cout << "pl_mm2s_2 completed" << std::endl;
116     run_pl_s2mm_1.wait();
117     std::cout << "pl_s2mm_1 completed" << std::endl;

And also #include "graph.cpp" in the begining of the file.

I have followed all the compilation steps to generate all necessary executable files.

I am getting below error :

Anything else?

I have also made changes in "graph.cpp" as suggested in "https://support.xilinx.com/s/question/0D54U000071JJKPSA4/graphxrtimplconfigureifnotyet-couldnt-find-any-configuration-for-graph-id-0error-adfgraphinit-failed-to-configure-graph?language=en_US" but it fails while compiling "host.cpp" with error : multiple declarations of main(), one in graph.cpp and another in host.cpp.

Please reply if any additional info is needed. Thanks.

Hi @soumitraghosh388,

In the VCK5000 the AIE graph cannot be controlled from the x86 code.

Please watch the End-to-End Development Flow with the VCK5000 here https://www.xilinx.com/products/boards-and-kits/vck5000.html#ai-engine

[mariodruiz]

If you have access to the VCK5000 Versal Development Card Secure Site, you will be able to see a tutorial for PS Kernel Usage. This is the way to control the AIE graph, but it is not supported on this repository.

Thank you.
