Error Building Static Application using CMake (U250)

[aaqdas]

I'm getting an error message when building static application for u250. I run the following command

cmake ../CMakeLists.txt -DFDEV_NAME=u250 -DEXAMPLE=static

Error Message

Can you please look into the issue and update on this?

Another problem I face is that, once I have run CMake for one application, and I try to run CMake again for another application, an error is thrown

Hi! Regarding your first request, I looked into the cmake and it seems as if the N_DDR_CHAN-variable is not properly set for DDR-based platforms - I tried to address that in the latest commit, so you might want to give a try. However: We have decided to stop the support for any non-HBM platforms and will from now on only continue the development and support for the Alveo U55C accelerator card (see updated Readme). Thanks a lot for your understanding!

For your second request, I'd be happy if you could provide the full context (essentially your terminal-input) to get a better understanding of the issue.

Thanks for your feedback through requests - always appreciated!

Kind regards,

Max.

Hi,

Thank you for your support, Max. Do you know which commit had design that was fully tested on U-250?

I resolved the second problem by using /usr/bin/cmake instead of cmake. It was a problem with the CMake that comes with Vivado, which was set as default in my terminal. It didn't include the package for cmake_parse_arguments by default.

Hi!

I don't think that Coyote v2 was ever tested on U250. So I guess the last version that might work on this platform out of the box would be Coyote v1 (see branch "coyote_v1"). Depending on what you're trying to achieve, the functionality of this shell should be very similar, but the architecture is actually quite different.

Let me know if that helps you.

Best,

Max.

Thank you very much for your support, once again. I'll look into the first version.

I'm trying v2 at the moment, and it works for most of the part. I tried the static-shell with perf-local application and it works great. I actually wanted to test out the RDMA.

I get the static_routed_locked.dcp checkpoint in the correct directory i.e. /hw/static_routed_locked_u250.dcp. Then I run the synthesis of rdma-perf hardware which completes the entire workflow of make bitgen.

However, it doesn't show enabled RDMA in dmesg logs.

So, I tried my own custom CMake Script to Build What I Want, An RDMA Enabled Static Shell with Performance Tester.

if(EXAMPLE STREQUAL "static_rdma")
    set(BUILD_STATIC 1)
    set(BUILD_SHELL 0)
    set(BUILD_OPT 1)
    set(N_REGIONS 4)
    set(EN_STRM 1)
    set(EN_MEM 1)
    set(HBM_SPLIT 1)
    set(EN_RDMA 1)
    set(SHELL_PROBE 6)
    set(N_STRM_AXI 2)

    validation_checks_hw()

    load_apps (
        VFPGA_C0_0 "apps/rdma_perf"
        VFPGA_C0_1 "apps/perf_local"
        VFPGA_C0_2 "apps/perf_local"
        VFPGA_C0_3 "apps/perf_local"
    )

    create_hw()
endif()

Its configured properly and goes well until make bitgen where the following error is thrown in RDMA Implementation.

I believe the following errors are also caused by the first error. For reference, I'm working with Vivado 2022.1 as specified in the documentation.

[aaqdas]

I believe it may be a typo, since there's only one use of request_snk and there's extensive declaration and use of req_snk.
