Access QSPI from HPS C code without linux (bare metal)

Hi FPGA experts. I need your help for de1-soc. In the document http://www.mouser.com/catalog/specsheets/de1-soc_user_manual_v06.pdf it is stated that QSPI Flash can contain user data obious thin...

If you want a very easy-to-use driver, supplied with a working demo (verified to be OK on DE0-nano & DE10-nano), don't hesitate to request our free BSP.

www.code-time.com

The API of the driver has these 4 basic functions calls:

qspi_init();

qpsi_read();

qspi_write();

qspi_erase();

It can't be simpler than that.

    Hello i want to do the same.

    I am new developer for the Cyclone v SoC.

    I want to read and write from the QSPI flash in my HPS baremetal application. I want to write a very simple data in words format.
    e.g.
    write data 0xABCD, 0xCDEF, 0x1234
    and then read it back.

    I checked the following functions but they are not working for me.
    alt_qspi_write
    alt_qspi_read

    I think i need to initialize the qspi and do the other initialization etc before using alt_qspi_write or alt_qspi_read.

    Is there any one who developed a c program for QSPI of DE0-NANO-SOC?
    is there any built application project doing the simple read and write on QSPI?
