Multiple QSPI devices with nRF54H20

alexandre_duch

Hello,

The nRF40H20 has two Chip Select pins for the QSPI interface (P6.03, P6.13).
We would like to use the first one for an external memory (MX25R6435FZNIL0) with XIP and the second for another NAND memory (MX35UF2G24AD).

Can you confirm if ncs v2.8.0 supports multiple QSPI devices, one of which uses XIP?

Best regards,

Alexandre

    Hi Alexandre

    AFAIK all of this should indeed be possible, but it's worth noting that in the past NAND support has been rather limited, and you should contact the sales representative on the status of that being supported by the EXMIF as well. If you're willing to put in the work to make a driver for the NAND and USB mass storage yourself it's definitely doable. Other than that no specific limitations. The QSPI/XIP is indeed experimental in NCS 2.8.0, but more support will be added as of NCS 2.9.0 and onwards.

    Best regards,

    Simon
