Can't communicate MT25Q flash over Serial Flash Controller II Intel FPGA IP with quartus_pgm --nios2 or Nios Flash Programmer-- Error 18927 FAILED when using quartus_pgm

[RPind1]

I Can't communicate (with Nios Flash Programmer or quartus_pgm) with a flash chip ( MT25QU1G ) on an Arria V via the Serial Flash Controller II on the NIOS processor. (We can however use the chip to configure the FPGA using AS over the dedicated pins -- programmed through a .jic with Quartus Prime Programmer)

 quartus_pgm --nios2 --debug

with and without every permutation of

--base=0x10000000     

--epcq

--epcs

--csr=0x7000

--dualdie

All these commands fail with:

==========================

The Programmer (Serial Flash Controller II IP) is running at 10Mhz (well below fMAX of 50Mhz)

Hi,

Can you explain what do you mean by having the Programmer running at 10MHz? Do you mean the NIOS processor clock frequency?

Can you please share with us the Qsys design (screen shot is enough) and check the flash IP clock?

Regards,

[RPind1]

I should have said "Serial Flash Controller II " IP in Qsys instead of "Programmer." FYI the NIOS is running at ~ 83mhz in this design

[Ahmed_H_Intel1]

Ohh,

sorry for the late reply, The serial flash controller requires 25MHz, sorry why you use 10 MHz? I don't this gonna work.

[RPind1]

Hi Ahmed. I don't see any requirement on a MINIMUM speed. Can you point me to that documentation. I have only ever seen an FMAX published. I used 10Mhz because it was the only available clock I had under FMAX. I can and will adjust to FMAX once working it I have the routing resources
