2nd cameras d435 on Jetson Nano loops in pipeline start up

Hi,

I'm having the following problem.

I try to have 2 pipelines. The 2nd pipeline loops in pipeline.start().

This happens both in the following python script:

pipe = [None] * n_cam

configs = [None] * n_cam

for i in range(n_cam):

configs[i] = rs.config()

configs[i].enable_device(SN[i])

configs[i].enable_stream(rs.stream.depth, width, height, rs.format.z16, 30)

configs[i].enable_stream(rs.stream.color, width, height, rgbType, 30)

configs[i].enable_stream(rs.stream.infrared, 1, width, height, rs.format.y8, 30)

pipe[i] = rs.pipeline()

pipe[i].start(configs[i])

and in the following c++ script:

    std::vector<rs2::pipeline>  pipelines;

    for (auto&& dev : ctx.query_devices())
    {
        rs2::pipeline pipe(ctx);
        rs2::config cfg;
        cfg.enable_device(dev.get_info(RS2_CAMERA_INFO_SERIAL_NUMBER));
        pipe.start(cfg);
        pipelines.emplace_back(pipe);
    }

It does not happens always, if I swap cameras sometimes it works fine.

But i cannot define why?

There is someone that can help me?

There is a safe plug and play procedure to start up to 4 multicamera in parallel onto jetson nano?
