Building TF-M : error: 'NRF_UARTENRF_SECURE_UART_INSTANCE' undeclared (first use in this function)

[nponsard-inria]

Hello,

I'm trying to build the trusted firmware M for the nrf9151. 

I did the following steps: 

• git clone git.trustedfirmware.org/.../trusted-firmware-m
• cd trusted-firmware-m && mkdir build     
  
• cmake -S . -B build -DTFM_PLATFORM=nordic_nrf/nrf9160dk_nrf9160 -DCMAKE_BUILD_TYPE=Release
• cmake --build build -- install

And I get the following build error: 

/home/nponsard/git/trusted-firmware-m/platform/ext/target/nordic_nrf/common/core/target_cfg.h:38:36: error: 'NRF_UARTENRF_SECURE_UART_INSTANCE' undeclared (first use in this function)
  38 | #define NRF_UARTE_INSTANCE(id)     NRF_UARTE##id
     |                                    ^~~~~~~~~

There's more output but that seems to be the more relevant lines.

I don't understand what I missed, do I need an additional dependency ? I'm on arch linux.

Thanks in advance,

Nils PONSARD

Hello,

I have not tried to build TF-M from here. In general it's recommend to use our integration of TF-M in the nRF Connect SDK: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/security/tfm/index.html#ug-tfm.  Are you not intending to use our SDK?

Downstream fork of TF-M used in the SDK: https://github.com/nrfconnect/sdk-trusted-firmware-m 

Best regards,

Hello,

Thanks for your answer,

I am trying to run an OS written in Rust (Ariel-OS) that doesn't use the sdk. It wroks fine in S mode without TF-M, but I want to use the modem of the nrf9151 and it requires to be in NS mode.

I tried to clone and build the fork you linked but I get the first command when running the first cmake command:

fatal: invalid reference: f985bee
CMake Error at mbedcrypto-subbuild/mbedcrypto-populate-prefix/tmp/mbedcrypto-populate-gitclone.cmake:61 (message):
 Failed to checkout tag: 'f985bee'

Regards,

Hello, 

Thanks for the clarification. I quickly tried to build the same using the v2.2 release branch (https://git.trustedfirmware.org/plugins/gitiles/TF-M/trusted-firmware-m/+/refs/heads/release/2.2.x), and that worked. The build error suggests that NRF_UARTE_INSTANCE(id) macro is being used where the id (NRF_SECURE_UART_INSTANCE) is not a numerical value corresponding to one of the UARTE instances.

Maybe you can try to check out the same branch to see if it works on your end as well. Another alternative may be  to compile the TF-M binary using the nRF Connect SDK, then use this precompiled binary in your project.

Best regards,

Vidar

Building on the tag `TF-Mv2.2.0` works, thanks !
