Nios2 system error in SOPC Builder

[Altera_Forum]

Hi all! 

 I try to modify picture viewer(Cyclone III starter kit + NEEK) to Cyclone III development kit(EP3C120F780C7) + NEEK. In SOPC Builer, i meet error message.  Error: ext_flash.s1: Appear at more than one address(0x08000000, 0x10000000) Error: ssram.avalon_tristate_slave: Appear at more than one address(0x14000000, 0x0c000000) Please help me.... Thank you.

Certainly, you will get errors as you have overlooked so many clock-crossing bridges! Possibly you need to re-connect 'tse_ssram_clock_bridge' to 'flash_ssram_pipeline_bridge'. After doing that mentioned error would be reduced but you will have other address alignment errors as I can see many clock-crossing bridges in your design. I suggest you to start from scratch add component one by one and see how things moving.

Hello rivaldo2000, 

 Did you try "Auto-assign Base address" option in the "system" tab? This option reorganizes automatically all peripheral addresses of your memory map.  Anyway, I agree with Ketan, if "Auto-assign base address" doesn't work, restart from scratch with only your CPU and add one by one all peripherals to see where is the error (do a generate system each time).  Have Fun  -Pierre
