Two x NIOS II boot from EPCQ in Quartus 13.1

Hello,

It seems that there are a bug in Quartus software for programming the EPCQ.

The following workaround (http://www.altera.com/support/kdb/solutions/rd11192013_118.html) provided by Altera solve the problem (at least for one NIOS II)

In my design I have two NIOS II's implemented in FPGA.

To program the FPGA configuration + first CPU + second CPU into the EPCQ, I followed the exact step provided in the above link with slight modifications (in red) as shown below:

Step 8.

a. sof2flash --input=hw.sof --output=hw.flash --epcq -verbose

b. elf2flash --input=sw1.elf --output=sw1.flash --epcs --after=hw.flash -verbose

c. elf2flash --input=sw2.elf --output=sw2.flash --epcs --after=sw1.flash -verbose

Step 9.

a. nios2-flash-programmer --epcs --base=0x4081000 --device=1 --instance=0 hw.flash

b. nios2-flash-programmer --epcs --base=0x4081000 --device=1 --instance=0 sw1.flash

c. nios2-flash-programmer --epcs --base=0x4081000 --device=1 --instance=0 sw2.flash

result: the FPGA configuration is uploaded from EPCQ and FPGA is booted up, BUT both CPU's are not functioning (i am not sure if it is uploaded or not).

Any idea or advise?

Thanks in advance.
