spi_init error using AD7134_EVAL board with zedboard running no-os

I am getting an error when the spi_init routine is run.  This routine returns FAILURE.

    ret = ad713x_init(&ad713x_dev_1, &ad713x_init_param_1);
    if (ret != SUCCESS)
        return FAILURE;

I'm using this version of no-os...https://wiki.analog.com/resources/tools-software/uc-drivers/ad713x?s%5b%5d=ad7134

How can I resolve this issue?
