    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

    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.
