Sdram connected to nRF52840

[buja]

Hi,

A general question regarding the connection of an external SDRAM to nRF53/nrf52840 to store data.

Just curious what will happen if different threads access sdram (non-shared data) at the same time. Eg:- two arrays arr1[4096] and arr2[4096], both stored in sdram. 

Is it okay if threadA access arr1[] and threadB access arr2[] at the same time. Is any synchronization tech840nique required ?

Hello

What peripheral would you use to communicate with your external RAM?

Either way I imagine it would make sense to have a resource like this locked by a mutex, depending on exactly how you use it this might happen automatically.
