FSMC PSRAM setup time

[Moamen Ayman]

Hello, I am trying to test PSRAM memory on STM32L4R9-Discovery board (STM32L4R9AI), I still don't understand how to calculate the PSRAM setup time (address setup time), (data setup time), (data hold time) and (bus turn around time) could someone explain to me how to calculate these times in AHB cycles based on the time table in the memory datasheet in ns.

I modified the heap side to 0x20,0000 (2MByte the size of the new memory), is that how it should be configured?

I have attached the basic setup I did on STM32CubeMX for FMC and heap size. and the PSRAM datasheet

Thanks!

this is the new memory region I adjusted in IAR linker settings
