Hi Sigurd,

This message just to highlight that I verified your answer but in my tickets list the post still is on "Waiting".

You likely want to add TF-M after, so do not hesitate to do that.

I just advocate that you make it work without first.
This is also a good hint to where the error happens, and that it is probably related to adding TF-M.

Let me know if you got any more questions

Ok, i think i got the point. As you foresaw, building cpuapp and not cpuapp_ns works.

Thank you

That is for the TF-M build of the board.

When first testing for a custom board, I recommend that you start with nrf5340dk_nrf5340_cpuapp and then go to the TF-M version after non-TF-M works.

Reason that build file does not have the SPU, is that TF-M is controlling the SPU instead of the application.

The board name is "nrf5340dk_nrf5340_cpuapp_ns". You can find attached the build/zephyr/zephyr.dts file of the build (Tollchain/SDK 2.3.0) for this board. I just rebuilt to be sure i was not hallucinating, so i can confirm it's the right file 🙂

I can find this in my nRF5340DK build.
What is the exact board name you build for here?
Which sample do you use?

Hi Sigurd,

thank you for your feedback. I cannot find "SPU node" neither in my custom board nor in the nrf5340dk built zephyr.dts file. However, nrf5340dk fully builds, while my custom board fails to build.

Maybe this issue could be related to the previous &sram0_shared issue? I'm wondering if in the custom board creation process there could be some missing dependencies somewhere?!

Hi,

CONFIG_HAS_HW_NRF_SPU is a Kconfig option automatically generated by the devicetree: https://github.com/nrfconnect/sdk-zephyr/blob/fcaa60a99fa9d5256078ed28557856ec3709cfa9/soc/arm/nordic_nrf/Kconfig.peripherals#L206-L207

I suggest that you start by checking on your SPU node in the custom board DTS files.

Tip: To check the built DTS-files, you can have a look at build/zephyr/zephyr.dts

Regards,
Sigurd Hellesvik

Discovered something that could provide useful. I back-tracked the fprotect error on the Cmake file where it is generated. I studied the possible if conditions and from what i searched this line should be true but it is not:

if (CONFIG_HAS_HW_NRF_SPU)
  set(FPROTECT_SRC fprotect_spu.c)

Based on KConfig reference for CONFIG_HAS_HW_NRF_SPU the selection chain should be

CONFIG_HAS_HW_NRF_SPU ---(selected by)---> SOC_NRF5340_CPUAPP ---(selected by)---> SOC_NRF5340_CPUAPP_QKAA

where the last symbol is already present in my defconfig file. Even the dependencies of the symbols are fine, so i really don't get why that if condition is not triggered :S.
