Hello,

I apologize for the delayed response. My last reply altered the status of this case, causing it to disappear, and I only discovered this two days ago. I appreciate you stepping in and checking the status.

As a starting point, I recommend looking at our Developer Academy course on DFU and bootloader, which explains multi-image DFU for the nRF5340. Please refer to the minimal configurations used there. How are you defining the external flash in the overlay file? See this overlay.

It is not necessary to change the slot names when dealing with multiple cores. I think the only benefit of this might be to distinguish the partitions more clearly.

Could you check the "pm_config.h" file inside the build folder? You can find this file at build/zephyr/include/generated/pm_config.h. Ensure that all the partitions are present.

Kind Regards,

Abhijith

nRF Connect SDK version is 2.6.1

This is the build error:

xyz/bootloader/mcuboot/boot/zephyr/include/sysflash/pm_sysflash.h: In function '__flash_area_ids_for_slot':

It looks like mcuboot_primary_1 is not being found even if I have it in my pm_static file.

mcuboot_primary_1:
address: 0x0
size: 0x40000
device: flash_ctrl
region: ram_flash
slot2_partition:
address: 0x00000
orig_span: &id003
- mcuboot_primary_1
device: flash_ctrl
region: ram_flash
size: 0x40000
span: *id003

Let me know if you need any more information.

Hello,

I am letting you know that I have been assigned to this case and have started looking into it. Could you tell me which version of the nRF Connect SDKs you are using here?

You could also share the error you are getting; you may share the whole log here (use the insert tab for that). On reading your query, I think you can do this by including the partition inside the pm_static file, and editing the dts file will also make it work, but it's not a recommended method. I will get back to you on Monday with some more information regarding this.

Kind Regards,
