Hi All!
What is correct IP to connect EPCQ32-A configuration flash to Nios II-based system (on Cyclone IV). There are four options in Quartus 18.1:
- Legacy EPCS/EPCQx1 Flash controller
- Serial Flash Controller
- Serial Flash Controller II
- Generic Serial Flash Interface
Nios II boots from EPCQ starting at some address (after fpga image).
The main problem is that we are unable to use quartus_pgm utility with --nios2 command line flag. We tried all of the IPs above, but it fails in different ways:
- Unable to reset and pause target processor
- Unable to erase flash
- Verify step passes, erase step fails
- Unable to locate CSR register while erasing (--erase_all option), but programming works ok with same --csr setting
- Crashing with access violation after correct programming (this is with option #2, but only if EPCQ base address is not 0x0)
Access violation arrives every time quartus_pgm exits with success (code 0x0).
Is there any reference design or template for this configuration (Cyclone IV, Nios II, EPCQ-A)?

I think I've figured out the root cause of all problems. EPCQ reset was not connected to Nios II debug_reset_request signal.
But the problem with access violation persists. Every time quartus_pgm finishes programming of EPCQ flash (with --nios2 option)
it returns code 0x0 and programs everything correctly, but displays an access violation message.
Below is the full log of quartus_pgm utility. First it programs *.sof file, then programs *.flash files.

Hi,
Can you try to program example given in the link also follow the steps from AN736
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an736.pdf
Let me know if your are able to program it or if you need any further assistance.

Hi, Anand
We have solved all problems with hardware right now (please read log in my second message). The only problem
is that quartus_pgm --nios2 crashes with access violation after successful programming. This problem is also
present in Quartus 17.1 with the same trace message.
As a solution, I've moved from using quartus_pgm with --nios2 flag to JIC-file based programming flow.
I've composed JIC-file with SOF data, Nios II program, DSP program and custom settings.
And it works perfectly (erasing only modified regions) and programming succeeds every time.
