How to configure and use nRF9160DK external flash mx25r6435f

[Liza]

Hi,

I use the nRF9160dk and I want to use nRF9160's external flash mx25r6435f to store a few data.

There are few related posts from too many years ago. Could you provide a clear guideline to configure and use it?

board: nrf9160dk

SDK: v2.5.0

Thanks,

Liza

Because we use only nrf9160 sip on our final board, so if there has any method that will not use nrf52840?
