Q:without epcs,why does not start uclinux

ssram,flash,etc WITHOUT EPCS！

quartus only has the avalon_cy7c1380_ssram IP core

No avalon_cy7c1480_ssram IP core!

so

I wanna download the uclinux with loading in cfi_flash(PC28F00AM29EWL, 1Gb)and excuting in the ssram（72Mb,[B]，so only 2M is recognized in SOPC or QSYS）.

-----------Means not recognizing the ssram IP to excute the uclinux correctly!!----------

make linux image ...then nios2-flash-programmer to the FLASH

starting processor at reset vector

nios2-terminal

then there's no response ...
