STM32L496G-Discovery PSRAM problem

Hey, I'm using STM32L496G-Discovery before our PCBA will arrive. According to the docs there is 8Mbit

(1MB) PSRAM on board, but in ALL ST examples with the board just 64k of it defined into icf

(from 0x1000000 to 0x1000ffff), I use IAR IDE. When I try to change it to 1MB

(from 0x1000000 to 0x100fffff) I receive HW fault at debugger power up state).

LCD shares bus with PSRAM, I disconnected it, but still it doesn't help.

Could someone help and provide the way for (if needed) hw modifications and configuration

in order to use whole 1MB PSRAM space.

Thanks,

Boris

Where do you change that, and what are the material consequences of that change?
