Re: Does anyone have success on programing EPCQ in Q16.0 with nios2-flash-programmer?

Altera_Forum · ‎07-22-2016

I'm working on a Cyclone V GX Custom Kit with EPCQ256 and Altera Serial Flash Controller Core NOT Legacy EPCS/EPCQx1 Flash Controller.

Programming EPCQ with .jic is fine, boot from EPCQ both hardware and software seem ok, but not 100% functional, I think the copy rwdata from EPCQ to OCRAM might have some flaws.

So I need to debug it with Execte-In-Place Method, If the .hex in .jic is same as my NIOS .elf the debug will be going without problem.

But every time I changed the source code, I had to rebuild .hex, repack it into .jic and download it by Quartus programmer again, it's really time consuming.

In order to be more inefficient, I'm trying to update EPCQ256 with nios2-flash-programmer.

I was trying to use the flowing command, but failed with No EPCS registers found.

There were tons of No EPCS registers found explained in this forum, but most latest solution were only related to Q13.0 and even ancient Q10.0, not help at all.

So anyone has any idea?

And a very strange thing, the Nios II Flash Programmer GUI generate some scripts that would only work for CFI FLASH

See, there is not --epcs/epcq arguments at all. I guess nios2-flash-programmer can only cope with Legacy EPCS/EPCQx1 Flash Controller.

I think the whole EPCS tool set must be broken.

Another thing, for this application note

Boot NIOS from EPCQ flash:

"HELLO WORLD!" Demo is OK.

uc/os II BSP did not work.

I can't edit my original post due to the PHP exceptions.

I post the larger version of QSYS here for reference.

Can you try using Quartus II Programmer instead of Nios II Flash Programmer to program the .jic file?

Yes, I have found a way around the Nios II Flash Programmer, I have thought the .jic would erase the whole EPCQ chip before programming any new data, but actually it only erase the part where needed.

Did you managed to resolve your problem? How do you do that?

Altera_Forum · ‎01-09-2017

Yes, I did. In fact, the tutorial was wrong. You need to uncheck everything in BSP EDITOR, otherwise you will not be able to debug or download your NIOS SW through jtag if your reset vector is set to epcq.

Then download the jic file through Programmer. That's all.

Good day!
