Hi Bhavin,

Please take a look at this sample: https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/subsys/fs/littlefs/README.rst 

It supports the 52840DK and ca be adapted for the 52832 as well, by creating a overlay file for the SPI memory similar to this: https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/subsys/fs/littlefs/boards/nrf52840dk_nrf52840_spi.overlay 

You can interface the external memory via SPI peripheral.

Best Regards,

Priyanka
