FPGA configuration and Nios-II application software into the EPCS

Hi, 

 

I have the design where i have FPGA logic interfacing with Nios-II. I used Quartus Prime 16.1 Standard Edition. I used Cyclone-IV Device EP4CE55. 

 

I want to put the FPGA configuration and Nios-II application software into the EPCS without using EPCS Controller in Qsys. Is there any method to do? 

 

Thanks in advance 

 

Regards, 

Nandish Jasani.

Hi, 

 

Any reason not to use the EPCS Controller?

Hi, 

 

Thanks for your reply. 

 

I used Two Nios-II in Qsys, one Nios already interfaced with EPCS Controller, but another is not. But both Nios-II systems are independent configure in a Qsys.

Hi, 

 

How many EPCS devices are you using? Do you plan to boot both Nios from the same EPCS memory? 

You may refer to https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/tt/tt_nios2_multiprocesso... "Boot Addresses" section for details.

Hi, 

 

Acutally both nios configured in Autonomous method, both are isolated system and i have only one EPCS Device in my board. EPCS memory used only for one nios. For another i want to use FPGA Memory.

Hi, 

 

Sorry I am getting confused. You mean one Nios is using EPCS while another is using On-Chip Memory? 

Can you be more precise in describing your problem?

I used Two Nios-II in Qsys.
