Flash partitions for nRF54L15

[Haresh05]

I am working on nRF54L15 and I want to store some user data in flash and for that I want to define the partitions.

I have selected the Target: nrf54l15dk/nrf54l15/cpuapp/ns and I am exploring the nvs  example.

When I check the Memory report I found multiple partitions defined on same address as attached in image. I tried to find where this is defined but not found it. Can anyone help me understand this partitions and let me know where it is defined?

Hi,

I think you will find this page helpful: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/bootloaders_dfu/mcuboot_nsib/bootloader_partitioning.html. In short, what you see here w.r.t the "multiple partitions in the same address space", is just a hierarchical way to sort thing. It doesn't mean that you have both a nonsecure storage and a storage partition in the same address space. It means you have a partition that is dedicated as nonsecure storage that starts at x0015f000 and that the first partition within this region is the nvs_storage that starts there and takes up all of this space. A similar approach goes to the other "overlapping" groups as well, for instance tfm_storage which is 32k and has both tfm_its and tfm_ota_nv_counters within this memory region

W.r.t memory report you can also read more here: https://docs.nordicsemi.com/bundle/nrf-connect-vscode/page/guides/memory_overview.html 

Let me know if this answers your question

Kind regards,
Andreas
