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

Hi MK,

By changing the reset vector offset changes the location of the reset vector relative to the memory module’s base address and might affect your designed system.

Here is a link for your reference: https://www.intel.com/content/www/us/en/docs/programmable/683836/current/reset-vector.html

I am glad your project is compiled and pinged successfully with the correct base address.

Hope this clarifies your doubts.

Thank you.

Regards,

Kelly
