nRF91 PSRAM support

Hello,

We're needing a lot more RAM than what nRF91 has, does current nRF Connect SDK support parallel PSRAM on Zephyr somehow or is the development on a roadmap?

  • Thanks, if PSRAM cannot be supported maybe there would be another way of reaching our goal. 

    We need to send a stream of data to the Cloud. Data is coming in at roughly 100 kBps for at least 5 seconds, so 512 kB to 1 MB fast enough storage would be needed. What kind of approaches we could use here? Write endurance has to be at least 10 000 cycles, so some flash might also work for us if it can keep up with the data rate. 

    The application should work with NB-IoT and LTE-M so streaming data as it comes directly is probably not feasible.
