Honored ContributorThanks for replying, Mosko9. Initially, we wanted FPGA to access data stored in the flash and didn't want to use the bridges to do this. So, wanted to know how to access HPS pins from FPGA. But now, we decided that we are going to read the data in the flash just once on power up. So, we'll be using HPS and bridges.
But still, I would like to know how to access HPS pins from FPGA. If you know, could you please tell me how? Thank you, Karthik
New ContributorHello,
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?
