Partition Manager Configuration

[benna]

Hi all,

We started from the asset tracker v2 application and we want to add a partition to the non secure storage just to save some additional data to nvs.

I'm a bit confused what the proper way is to configure this today. Is it correct that there are two approaches?

1. The device tree overlay
2. Partition manager

I've tried to configure a pm_static.yml by placing it in the configuration folder of my board, and set the env variable PM_STATIC_YML_FILE to this file (as specified here) in my CMakeLists, but this doesn't seem to do anything.

# Partition Manager file
set(PM_STATIC_YML_FILE ${CMAKE_CURRENT_SOURCE_DIR}/configuration/${BOARD}/pm_static.yml)

What are we missing here?
Are there some additional configuration options missing?

Or should we use the device tree overlay?

Thanks!

Hi,

In the nRF Connect SDK, when you have a multi-image build, the Partition Manager is used automatically, and it will override the device tree partition layout.

When building an application for the non-secure domain (e.g. nrf9160dk_nrf9160_ns), TF-M is automatically included, so you will always have a multi-image build.

Can you share the CMake part of your build output?

Did you try to delete your build folder before you built the project?

Best regards,

Didrik

Hi Didrik,

Thanks for the reply.
I've deleted the build folder, but no dice, same result. I bet I'm doing something wrong somewhere.

Thanks for the help.

Try to set the PM_STATIC_YML_FILE earlier, above the find_package line.

That way, the variable is set when the Partition Manager is run.

Right on the money, thanks!
