Hi Jérôme,

I come back to you as I managed to target my problem...

I attached to the mail my sopc design. When I put everything to onchip mem in the system library properties, everything works.

Then, if I put everything to ssram or ddr-sdram except program memory (to onchip mem), nios II compiles but the program does not work. Then, if I put everything to ddr sdram, I have the traditional :

Verifying 00010020 ( 0%)

Verifying 04000000 ( 2%)

Verify failed between address 0x4000000 and 0x400369F

Leaving target processor paused

I don't understand how system library properties is related to quartus II.

Why doesn't it work with ssram ? I did not even add it like the ddr-sdram, it was already in the original design...

Thanks,

Myriam
