Working c project for "qspi" read and write from hps arm controller baremetal

Question

Hello,
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, 0x1234and then read it back.
I checked the following functions but they are not working for me.alt_qspi_writealt_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?

i found the answer to my question.
in attachment is the source code.
you can import the code in the DS-5
then in the main.c you can find the QSPI read and write.

Hi,Unfortunately, we do not have example in baremetal environment, if you opt to there are examples in:https://code-time.com/default.htmlIf you want to access the QSPI in the HPS side, you need to configure it first, you may refer below for guidance:https://rocketboards.org/foswiki/Documentation/SocBoardQspiBoothttps://www.intel.com/content/www/us/en/programmable/documentation/lro1404103165481.html
