How to use barefoot runtime API (C++) to manipulate my tofino switch?

[jinzhao]

I try with the following 

int main()

{

    std::shared_ptr<bfrt::BfRtSession> session;

    session = bfrt::BfRtSession::sessionCreate();

    if(session == nullptr)

        printf("fail to open session");

    std::vector<int> v;

    bf_rt_target_t dev_tgt;

    dev_tgt.dev_id = 0;

    dev_tgt.pipe_id = ALL_PIPES;

    const bfrt::BfRtInfo *bfrtInfo = nullptr;

    auto &devMgr = bfrt::BfRtDevMgr::getInstance();

    bf_status_t status = devMgr.bfRtInfoGet(dev_tgt.dev_id, "l2_program", &bfrtInfo);

    if(status != BF_SUCCESS)

    {

        printf("ERROR: Cannot get BfRt info: %s", bf_err_str(status));

    }

    return 0;

}

But when I run the program, it says 

ERROR: Cannot get BfRt info: Object not found

I have start my p4 program, why this error happens?

Wrong forum. This forum is for FPGA devices. You want an Intel networking forum.

Hi @jinzhao,

Thank you for posting in Intel community forum and hope all is well.

As further understand the mention product which is eternet related instead of FPGA, hence will be moving the message to the correct community, and the relevant team will get back to you.

Best Wishes
