how to implement simultaneous dfu on 5340 ncs2.4 without external flash

[Ivan Zhang]

As title, I try to implement simultaneous dfu without external flash on 5340, but it always show that  'PM_MCUBOOT_PRIMARY_1_ID' undeclared.

if use external flash, my project can work well. when i disabled QSPI and  add pm_static.yml as below, the project compilation reported the error.

so  how to implement simultaneous dfu on 5340 ncs2.4 without external flash.

Here is a sample:

5700.peripheral_lbs_dfu.zip

Disclaimer: This code/configuration is not thoroughly tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.

This sample points the partition manager to an external flash even though it does not exist. That is becasuse it automates some building processes.
However, this should be fixed soon, see

https://github.com/nrfconnect/sdk-nrf/pull/10060

https://github.com/nrfconnect/sdk-mcuboot/pull/235

There PRs are not nessecary for you to patch yet, the sample should work without them as is.

I am currently working on an nRF5340 project and am also interested in simultaneous dfu without external flash.

Unfortunately, I can't get the 5700.peripheral_lbs_dfu example to work on ncs 2.5.0.

If I understand it correctly from the github links above, this may be a new feature in ncs 2.6.0. Is that correct?

Regards,

Mark

The sample should work I beleive. Can you explain your issue?

Tge PRs are still Open, so I can not say anything about when they will be merged and included into the nRF Connect SDK.

When I build peripheral_lbs_dfu "as-is" from the attached zip file (5700.peripheral_lbs_dfu.zip) for "nrf5340dk_nrf5340_cpuapp_ns" on ncs 2.5.0, I get the following:

H:/Documenten/Projects/ZephyrTestProjects/peripheral_lbs_dfu/prj.conf:21: warning: attempt to assign the value '"2.3.0+0"' to the undefined symbol MCUBOOT_IMAGE_VERSION

error: Aborting due to Kconfig warnings

When I comment (#) the MCUBOOT_IMAGE_VERSION in prj.conf, to exclude it, then I get the following error:

value indirectly from other symbols. See
docs.zephyrproject.org/.../kconfig.html and/or look up
BOOT_ENCRYPT_RSA in the menuconfig/guiconfig interface. The Application Development Primer, Setting
Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful
too.

The version error is due to the new versioning system in v2.5.0

Try to remove CONFIG_BOOT_ENCRYPT_RSA from child_image/mcuboot.conf then?
