Hello ALL,
I am trying to use MCU boot with my application. I am using NRF916DK and it has external Flash similar to NR52840DK board. Now when I am creating a partition on external Flash and point LittleFs to that storage partition, after compiling when I see the partition.yml in the build folder, the LittleFs always in the primary Flash. I have tried few options as seen in the code but nothing is working. Can somebody please guide me on how I can enable these partitions and point secondary Image and littlefs to those partitions.
Here is my overlay file
