nRF5340_audio buildprog aborts on Kconfig warnings

[Kai Harrekilde]

I am trying to build the nrf5340_audio demo application (\ncs\v2.5.1\nrf\applications\nrf5340_audio) using the suggested build script (buildprog.py).

I have been able to complete all the exercises in the SDK Fundamentals course with the instalation.

I have set the S/N in the nrf5340_audio_dk_devices.json, removed the CONFIG_NFCT_PINS_AS_GPIOS from Kconfig.defaults (as it generated a warning that it is deprecated and the superceeding symbol is already set in soc/arm/nordic_nrf/Kconfig), and added CONFIG_SHELL_VT100_COMMANDS to prj.conf to satisfy the CONFIG_SHELL_VT100_COLORS requirement.

buildprog.py terminates with 18 warnings about configuration options that are "defined without a type". I'm been digging into the Kconfig files, but do not find anything obvious between the symbols that generate warnings and those that do not (e.g. CONFIG_RESET_ON_FATAL_ERROR vs CONFIG_BT).

I'm begining to suspect that there is something odd with the zephyrproject setup, as I have the 3.5.99 version installed, and not the latest official 3.5.0 release (and I have no clue to why I got 3.5.99 over 3.5.0). I see that there's also a recommendation to stay away from python 3.12 due to dependency problems, but as far as I can tell, my v3.12.1 installation works .

Here is the output from a buildprog.py run:

Hello, 

Sorry for the late reply. I will have a look at this and get back to you. 

Kind regards,
Øyvind

[Kai Harrekilde]

I did a parallel install of zephyrproject v3.5.0 to see if it made a difference.

It didn't

The warning about BT_ATT_ENFORCE_FLOW disappears, but otherwise the problem persists.

I just noticed that I forgot to mention that I had added CONFIG_NEWLIB_LIBC=y to the prj.conf file, but I have just confirmed that it made no difference.

[Øyvind]

Out of curiosity, are you using nRF Connect SDK or Zephyr OS directly?

[Kai Harrekilde]

I'm using the nRF Connect SDK (and VSCode, but thats not suggested for building this app, according to the docs).

[Kai Harrekilde]

Let me try. That'll probably be tomorrow. Setting it all up takes a while.

[Kai Harrekilde]

I am stuck on this.

[...]

Edit: OK, the --pristine option was what was needed to get it to pick up the new SDK location. There's just too much caching of information going on IMHO.

Unfortunately, it did not make a difference - the build process breaks the same way. I will either move or install an extra zephyrproject (v3.5.0) under c:/ncs tomorrow, just to rule out the too-long path theory.

[Øyvind]

I'm confused.

But you are referring to Zephyrproject 3.5.0

Kai Harrekilde said:

There should not be any reason to install zephyrproject. How did you install NCS? Through the nRF Connect for VS Code extension or our toolchain manager? 

Also, in your build output it states zephyrproject (Zephyr version: 3.5.0 (C:/Users/KaiHarrekilde-Peters/Projects/test/zephyrproject/zephyr)) where if you are using NCS, it states e.g. Zephyr version: 3.4.99 (/opt/nordic/ncs/v2.5.1/zephyr)
