more likely, your addressing is wrong.

None of that has anything to do with Nordic or the nRF52832.

The memory chip neither knows nor cares what microcontroller you use - it just behaves as described in its datasheet.

So you need to study the memory documentation, and do what it tells you.

Have you looked at the SDK for the SPI driver & examples?
