SDK1.2 NVS Changes

[phipi]

PM_MCUBOOT_STORAGE_ADDRESS and PM_MCUBOOT_STORAGE_ID seem to be no longer defined as of SDK1.2. As per the discussion here, I tried using DT_FLASH_AREA_STORAGE_OFFSET which seems to be working with MCUBOOT,however it is unable to read any settings written using the old SDK.

This means that if we FOTA these devices they will lose any hardware configuration settings that have been programmed. What's more is that it appears it's writing these settings to 0x86000 which I believe is the secondary partition for MCU_BOOT. We haven't gotten this far yet but I suspect that if we FOTA the devices it'll overwrite this area anyway.

What's the recommended way to store configuration parameters in a PM and FOTA compatible way?

Here's the partitions.yml generated by SDK1.1 and SDK1.2. As expected, I'm missing mcuboot_storage and I see it's also missing mcuboot_scratch. Can I just use the old partitions.yml as my static config for SDK1.2?

Yes! That should work fine.

I'm just testing this and it seems like if I put the pm_static.yml file in my application directory it works fine, however if I put it in APPLICATION_DIR/configuration/BOARD_NAME/pm_static.yml and then specify PM_STATIC_YML_FILE in the cmake command it does not work.

Is there a bug with the definition of the variable?

Nevermind, I see the attached link below is for the latest docs. What I'm trying to do isn't supported until 1.2.99
