Simultaneous FSMC usage on STM32F2

I am using an STM32F2 MCU and currently successfully executing code from external SRAM on FSMC Bank 1, NOR/PSRAM 1.
What I would like to do is also use the LCD on Bank 1, NOR/PSRAM 2 while executing from this external SRAM.
I have made the assumption that this is not possible simultaneously and would like verification of that?

Along these lines anyway, I have specifically placed any module that accesses the FSMC for the LCD into internal SRAM so that it is not executing instructions over the FSMC while trying to access the LCD but this hasn't worked.
I know the LCD works because the same code running exclusively from internal SRAM works OK.

Any thoughts?
