QSPI SUPPORT PSRAM

[David]

Could you please check whether 52840 can support memory map to QSPI PSRAM on QSPI interface? 

  

If yes, that means the compiler would see a big RAM space of 2~8MB QSPI PSRAM connected on QSPI interface, solve our memory shortage issue with wearable application. On 52840 we are facing RAM shortage in case of GUI application

Hi,

There is Execute in place (XIP) support on the QSPI peripheral of nRF52840.

In the SDK, you can find a QSPI bootloader Example.

Best regards,
Jørgen
