static assertion failed error with custom PCB

[DunKCubik]

Hi,

  just testing out a custom PCB with nrf9160 on it.

Have developed much on the nrf9160 dev kit and just about to port to our custom PCB.

Created a custom board and just tried to build the "hello world" sample but I'm getting lots of "error: static assertion failed like this...

C:\ncs\v2.3.0\zephyr\include\zephyr\toolchain\gcc.h:78:36: error: static assertion failed: ""
78 | #define BUILD_ASSERT(EXPR, MSG...) _Static_assert(EXPR, "" MSG)
| ^~~~~~~~~~~~~~

Builds fine for the devkit but not custom PCB.. HELP!!

Using nrf connect  SDK and toolchain V2.3.0

Cheers

Duncan

Think I've solved the issue. Apparently building for TFM (Trusted firmware) is not enabled by default when creating a custom board!

Managed to find a great post that explained this and how to add the configs to my custom board's defconfig file.

Why are they not carried over by default, or at least a warning given rather than vague "static assertion errors"?!!

I seem to waste so much time searching for answers to these issues when creating a custom board. Surely it should be documented officially somewhere (please prover me wrong if it is) It has taken 3 hours of my busy working day to solve this, when it should be simple!

Thanks to Raoul for this post...
