Interfacing to epcs64 from fpga

Hello Again,

I think I made small progress

I have noticed the option in ASMI Parallel "Disable dedicated Active Serial interface"

which makes my ASMI block explicitly route out the SPCS64 'SPI' signals

So I routed those signals out to my top level and I have specified constrains in my qsf file

to their actual pin location. One of the assignment is asmi_dataout to Pin_P26

Now the actual issue is that I get

Error (176310): Can't place multiple pins assigned to pin location Pin_P26 (IOPAD_X0_Y44_N62)

Info (176311): Pin asmi_dataout is assigned to pin location Pin_P26 (IOPAD_X0_Y44_N62)

Info (176311): Pin ~ALTERA_DATA0~ is assigned to pin location Pin_P26 (IOPAD_X0_Y44_N62)

If seems a dedicated pin ALTERA_DATA0 is already assigned to Pin_P26.

I have tried all I could in: Device and Pin Options -> Configuration/"Dual Purpose Pins"

but this error stays constant at my Fitter stage. The only thing I find in my qsf file about DATA0 is

set_global_assignment -name RESERVE_DATA0_AFTER_CONFIGURATION "COMPILER CONFIGURED"

which OI tried to comment but this line is always updated as per my settings in the "Dual Purpose Pins"

If I disable the assignment asmi_dataout to Pin_P26 just to give it a try things become even more interesting to me

Error (169094): Can't place pin asmi_dclk at location AM3 (PAD_256) because that location is a dedicated programming pin location

Error (169094): Can't place pin asmi_scein at location AM2 (PAD_257) because that location is a dedicated programming pin location

Error (169094): Can't place pin asmi_sdoin at location AM1 (PAD_258) because that location is a dedicated programming pin location

So my other 3 assignment fails as well.

Can I use the programming pins ASDO, NCSO, DCLK and DATA0 in user mode for my EP4SGX70?

What I want is to use the EPCS64 FLASH for user data and not for FPGA configuration at all.

It is interesting that if I don't enable "Disable dedicated Active Serial interface" in the ASMI IP the compilation is fine.

I am getting out of ideas. How to solve this?

Thank you
