EPCS replaced by EPCQ Error (with Cyclone III FPGA)

EPCS replaced by EPCQ Error (with Cyclone III FPGA)

[Ekta Unity]

Dear Sir,

In one of our old project cards, we were using *Cyclone III FPGA* along
with *EPCS64SI16N *memory.  Recently same card was manufactured but
as EPCS64SI16N is obsolete now, we used equivalent recommended MPN
*EPCQ64ASI16N*.

*Quartus 11* was used to compile the FPGA project; as it doesn't support
EPCQ, we generated new project in *Quartus 13*. SOPC file for NIOS also got
upgraded to QSYS version.

In Eclipse, one error is thrown as shown in image -* "Couldn't compute
FAST_CWD pointer. Please report this problem to public mailing
list cygwin@cygwin.com <cygwin@cygwin.com>."*

Also, while writing SOF file to EPCQ it throws error as shown in attached
image- *"No EPCS layout data - looking for section(EPCS-EF4017); Unable to
use EPCS device; Error code 8."*

Also, .pof and .rbf  files were generated by selecting EPCQ64 memory,
however, it resulted into the same error.


*Kindly help us to resolve these errors as we have to urgently program
firmware in these cards.*


Best Regards,
