    Hi MK,

    Greetings and welcome to Intel's forum.

    There is not specific reason why it is greyed out. It is according to the base address you set in Platform Designer. You have the flash address set to 0x10000000, and the offset to 0x08b00000. Therefore, flash will start access at 0x18b00000.


    Hope this clarifies your doubts.

    Thank you.


    Regards,

    Kelly

It's based off the base address you set in Platform Designer. So it looks like in PD you have this flash set at address 0x10000000. You set the offset to 0x08b00000, so the Nios accesses the flash starting at 0x18b00000.
