You are asking for 256 Kbytes of BRAM memory,
That exceeds the capabilities of the IP core (and likely your device as well).

Is this BRAM part of a Block Design (versus stand alone)?
If this is a stand alone core, then the depth should be editable. And the prior suggestion to regenerate the core is appropriate. However...
I had a similar situation when adding BRAM controllers to a BD. I discovered that the Memory Depth was calculated based on the AXI Address Range specified in the Address Editor. So if this BRAM controller is part of a BD, go to the Address Editor and modify the range. That should take of it.

word width 256 bits,
address size 1024 words.
256 * 1024 == ? bytes
/8 = 32 Kbytes (always should use a calculator ....)
Also always check the IP wizard limitations.
