Thanks for the info!

We are still using 2.0.0, I'll try 2.1 ASAP.

Didn't see any changes in change log.

Regards

Hi Giuliano,

Have you tested with the latest NCS 2.1.2?

The fix had been introduced from NCS 2.1.0. TF-M: Add support for storage partitions in external flash. by joerchan · Pull Request #7945 · nrfconnect/sdk-nrf (github.com)

Best regards,

Charlie

Hi Charlie,

Where are we with this issue? I faced the same problem as described here, but fortunately, the workaround seems to be working.

This is a show-stopper issue, it needs to be addressed ASAP.

Hi KFyatek,

I got some feedback from our development team:
We don't use BL2 but we do have region_defs.h file with a lot of partition information that just uses this. It seems we have misused the BL2 constructs (we probably didn't have time to rename and come up with something defined by us) so this is clearly something we should clean up.

We are a little pressed for resources in our team because of summer vacation, so I'm assuming the proper solution won't be available until maybe a couple of weeks. Sorry for the inconvenience, I will keep monitoring the development state and keep you updated.

Best regards,
Charlie
