It's not supported in that way.

Apologies if my question is unclear, but that portion of the documentation explains how to define regions as they are already defined in partition_manager.cmake.

My question is regarding whether regions can be defined on the user application/project level, outside of partition_manager.cmake. As mentioned before, I'd like to avoid forking the nRF Connect SDK repository, if possible.

Again, thank you for your support on this question!

See Partition Manager/Regions documentation.

That's good to know, thank you! With regard to my first question, is there a way to create custom regions in addition to the regions automatically created by the Partition Manager?

Thank you for your response. I've already read through all of the Partition Manager documentation, and I understand how to place partitions into the external flash region. What I'd like to do is create additional regions. If creating additional regions is not an option, I'd like to know if there is a designated way to support multiple external flash devices?

Referring to the Partition Manager cmake file in NCS 2.7 (the version I'm using), the external flash region is added based on the device assigned to the "nordic,pm-ext-flash" property in the device tree. If I have multiple external flash devices, is it possible to define multiple "nordic,pm-ext-flash" properties?

Hi,

You can check External flash memory partitions and see the nrf5340dk_nrf5340_cpuapp.overlay for nRF5340DK.
