Hello, 

 

I just want to know what are the limitation (on the code size) if we use NIOS on a FPGA without Flash Memory. 

 

Can I store in the EPCS memory all code that I want ? (with the only limitation of the size of the EPS) 

 

Thanks

Of course you can store both hardware (.sof) and software (.elf) into EPCS, then boot from EPCS. You can even use on-chip ROM to store some software images. 

 

To do that, you must add a EPCS controller in your SOPC system, let the reset address point to it. 

 

Important, go to ftp://ftp.altera.com/outgoing/download/ni...oader_patch.zip (ftp://ftp.altera.com/outgoing/download/nios/nios2_1.1_epcs_boot_loader_patch.zip) 

to download a EPCS bootloader patch, and follow the instructions it provides. 

 

If any question, ask me. I have succeeded to do so.
