QSPI and w25q64fv flash

[Stas]

Hi all. I try to configure QSPI example to work with w25q64fv flash. I connected all pins from flash to same pins on nRF as on PCA10056 DK board. After all i have "Data inconsistent" message.  I looked in to data array from flash and in it every element was equal to 0x88. I have a couple questions about how to configure driver to work with my flash and how to configure nrfx_qspi_cinstr_xfer function configuration structure.

//    // Switch to qspi mode
    cinstr_cfg.opcode = QSPI_STD_CMD_WRSR;

    err_code = nrf_drv_qspi_cinstr_xfer(&cinstr_cfg, temporary, NULL);

}

If i connect logic analyzer to IO0 pin i always get NRFX_ERROR_TIMEOUT err code.
