NRF52840 with Serial NAND

[Mickael]

Hi there, 

I have found a similar thread that dates back from a year ago (https://devzone.nordicsemi.com/f/nordic-q-a/29073/altering-qspi-address-mode) but I would like to have an update. 

It seems that back then QSPI IP wasnt compatible in terms of addressing with MICRON Serial NAND protocol - Is that something which has evolved or is planned to evolve in the near future? 

Thank you,

Mickael

Hi Michael,

As far as I know the answer in the thread you're referring to is still valid, i.e. the QSPI IP does not allow us to modify the addressing scheme to work with the  MICRON Serial NAND protocol. Hence the possible workarounds is to use the SPIM3 peripheral which supports 32MHz or use the custom instruction feature of the QSPI, see Sending custom instructions.
