That seems to work for me too.
So, what is the logic behind defining the location?
Before I added ZMS, this was the info (excluding otp and sram) in partition.yml:

app:
  address: 0x0
  end_address: 0x163000
  region: flash_primary
  size: 0x163000
settings_storage:
  address: 0x163000
  end_address: 0x165000
  placement:
  after:
  - app
  before:
  - end
  region: flash_primary
  size: 0x2000

and this was your suggestion for ZMS placement:

zms_storage:
  address: 0x15f000
  size: 0x6000
  end_address: 0x165000
  region: flash_primary

So would I be correct in saying that, generally, we fitted the zms_storage to end at the end of settings_storage, whereas I had been trying to place the zms storge to start after settings_storage.

Is that the general logic to apply?

--> To see where the end of used/defined Flash memory is, and fit the ZMS storage to end there, which will in turn, push one or two other storage areas to start at a lower address etc.

Thanks

Hi,

I test the smp_svr sample with this pm_static.yml file containing this:

zms_storage:
  address: 0x15f000
  end_address: 0x165000
  region: flash_primary
  size: 0x6000

and get the memory layout like this:
