extxip_smp_srv fails compiling for nrf5340dk non-secure target

[franchan]

Hello,

Working on Ubuntu 22.04 with nRF Connect SDK 2.6.1 for the target nrf5340dk_nrf5340_cpuapp_ns (= with TF-M).

My application image became too large. I want to split the app image over internal and external memory. I'm using extxip_smp_svr as example. It compiles & runs for the target nrf5340dk_nrf5340_cpuapp.

When building this sample for the nrf5340dk_nrf5340_cpuapp_ns target (with TF-M), compilation fails:

      |         ^~~~~~~~~~~~~~~~~~~

What do I need to change in this sample to make it compile for the non-secure target?

(PS my current project fails compiling with the same error when trying to add support for a split application image. That's why I looked into Nordic's sample to find how that is configured differently. Unfortunately it fails too. I saw the same error in the past when experimenting with CONFIG_BOOT_UPGRADE_ONLY=n in a multi-image build)

Thank you!

Kind regards,

Hello Amanda,
Did you or a colleague have time to further investigate this issue? Thank you!

Kind regards,

We are currently understaffed due to the summer vacation period, so delayed replies must be expected. I am sorry about any inconvenience this might cause.

Hello Amanda,

I got one step further making compilation now succeed. I added to boards/nrf5340dk_nrf5340_cpuapp_ns.conf:
CONFIG_MCUBOOT_USE_ALL_AVAILABLE_RAM=y

However after flashing, I see an error message from the MCUBOOT:
*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***
I: Starting bootloader
I: Image index: 0, Swap type: none
I: Image index: 1, Swap type: none
I: Image index: 2, Swap type: none
E: Unable to find bootable image

As a reference, when compiling without TF-M, I see the following:
I: Starting bootloader
I: Image index: 0, Swap type: none
I: Image index: 1, Swap type: none
I: Image index: 2, Swap type: none
I: Bootloader chainload address offset: 0x10000
