Hi,

I agree with you. I will report this as a improvement internally.

Kind regards,

Håkon

If I may, I would suggest to restructure this: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.3.0/nrf/app_dev/tfm/index.html#ug-tfm page a bit, the reference to the nonsecure_partition is under "migration from SPM" making it quite challenging to figure out why this would cause the issue.

I figured this one out, I did not wrap the Non-Secure partitions in `nonsecure_storage` in pm_static.yml.

This is the changed lines, for reference:

# This was configuration_storage before.
nonsecure_storage:
  address: 0xfc000
  span:
    - nvs_storage
    - static_configuration
  region: flash_primary
  size: 0x3000

nvs_storage:
  address: 0xfc000
  region: flash_primary
  size: 0x3000

static_configuration:
  address: 0xff000
  region: flash_primary
  size: 0x1000
