Occasional ContributorHi,
I am running NIOS II in Cyclone 10 LP 10CL120YF484.
The flash I am using is M25P64 which is qspi interface.
The problem is that EPCS flash controller is not compatible for Cyclone 10.
I am going to run qspi flash driver in NIOS so that I can read and write the flash.
The question is:
is qspi friver available? Could you please tell me the related resource of qspi driver and API?
Occasional ContributorHi Zhiqiang,
You may use Quartus version 20.1 Standard or later version. Then you can find GSFI IP in Platform Designer tool and refer to document description in link below to implement the booting from GSFI flash solution.
On page 8, it describes how to change the example driver to match the device from other flash vendor.
Hope it is helpful.
Occasional ContributorThank you for your reply!
This question is very critical for my design.
Is there a way by which I can run the GSFI IP on Quartus 18.1?
Occasional ContributorHi Zhiqiang,
I look at quartus 18.1std tool, it has GSFI IP too. Please try it.
The example design in quick start guide document is created in quartus 18.1std.1. So quartus 18.1std.1 should be OK to use this IP.
Cyclone® V FPGA – Generic Serial Flash Interface and Nios® II Processor Booting Design Example
If you are OK to upgrade to 18.1std.1 version, you may go to Intel® Quartus® Prime Standard Edition Design Software Version 18.1 for Windows and download update 1 setup package shown as below.
Hope this is helpful.
Occasional ContributorThank you!
I have already found a good IP(Serial Flash Controller Intel FPGA IP) that supports EPCS64 flash.
I have already tried this IP. I can program jic file via Quartus--> Tools--> Programmer.
but I can't program elf file via Eclipse--> NIOS II --> Flash Programmer.
Is there any way to program elf file or binary of C code if I use Serial Flash Controller Intel FPGA IP?
Occasional ContributorHi Zhiqiang,
Please refer to ug_nios2_flash_programmer document in link below, it provides the method of programming SOF and ELF file into EPCS flash.

Hope this is helpful.
Occasional ContributorThank you!
I have already read the pdf you mentioned. The picture I pasted is the result when I follow the pdf.
Occasional ContributorHi Zhiqiang,
Below table shows the minimum component set required. Have you enabled JTAG debug module level1 or greater?
Occasional ContributorOccasional ContributorHi Zhiqiang,
It is set in Nios II processor IP shown as below.
Occasional ContributorThank you!
By default, Platform Designer set JTAG Debug mode. I have never set or changed it.
Let's go back to my question:
I followed the settings in your link pasted above, but I am still facing the issue that NIOS II Flash Programmer can't find the device.
Could you please tell me how to solve that issue?
If it is possible, could you please contact me by me personal email: dpstill@126.com
Occasional ContributorHi Zhiqiang,
Since you can download JIC file, one possible solution is to convert elf file into hex file, and then add hex file into JIC file.
There are detailed online descriptions for your reference as below.

Occasional ContributorThank you！
If I convert elf into hex file according to your link, the questions are:
1) how to specify the start flash address of hex data?
2) how does NIOS know the start flash address of hex data?
3) will any component copy hex data from flash to RAM when NIOS boots?
Occasional ContributorHi Zhiqiang,
Please refer to below document and go through the description related to EPCS.
Occasional ContributorThank you!
I read the description related to EPCS in your link which is really helpful.
Occasional ContributorHi Zhiqiang,
The steps in item 4 as you described are the right solution to solve unrecognized SOF issue when run SOF2FLASH command.
Now you can generate hex file. Have you tried to add it into JIC file and program into flash as described in link below? Can your system boot from epcs flash now?

About error when you try Eclipse-->Run-->Run Configurations and Run, please kindly create a new case for it. Thank you for your cooperation.
Occasional ContributorThank you!
After I generate sw hex file, I add it to Convert Programming File tool with sof file, and generate jic file and then burn it to flash with Quartus-->Tools--> Programmer tools. The programming is reported successfully.
when I generate hex file, I cannot understand those parameters, could you please help to explain them? or paste the link about the explanation of those parameters? For example, what is auto_create_rpd? why is it on? what is it for? what is rpd_little_endian? why is it on?
what is srec-forceS3? what is srec-len?
After the upper programming, I don't know whether the SW(C code ) could be run in NIOS(FPGA) as I cannot debug it from Eclipse. The reason is pasted in my upper post.
Please see the third picture in my upper post. Eclipse report: Verify failed between address 0x1000000 and 0x100FFFF.
I doubt there is a mistake in my operations. when I generate jic file, there is a map file generated. please the the map file below pasted.
My doubt is:
swimage start address in flash is: 0x00367F06, why did Eclipse very the address 0x1000000 and 0x100FFFF?
where and how can I tell Eclipse the sw image start address?
BLOCK START ADDRESS END ADDRESS
Page_0 0x00000000 0x00367F05
swimage.hex 0x00367F06 0x00380875
Configuration device: 10CL120Y
Configuration mode: Active Serial
Quad-Serial configuration device dummy clock cycle: 8
Notes:
- Data checksum for this conversion is 0x49A89CF7
- All the addresses in this file are byte addresses
