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

[hsaee6]

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, 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?

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:

If you want to access the QSPI in the HPS side, you need to configure it first, you may refer below for guidance:
