How to fix KConfig warnings errors/Build errors of WiFi Fundamentals lessons(Recently updated tool chains and sdk to latest ncs 2.9 from 2.4, but have not checked the build then), what should I do to fix it?

[Arron]

Hello there,

I was going through the Wifi fundamentals courses lessons in nordic academy and was using ncs 2.4 version, I was able to give it a build for one example,(but not all give proper build)and you can see the output here. 

ncs 2.4

Then later I updated the tool chain and sdk to latest version 9 and I tried to give the build again and ran in to these issues here.

The errors are abort due to Kconfig warnings:(ncs 2.9)

Can anyone tell me where to look to fix this issue? I understand that sysbuild is introduced now, but this is something strange that I am unable to debug it for now as some.

Some observations: In the screenshots, lesson 2_1 builds properly with ncs 2.4 but fails with ncs 2.9, and  other lessons show similar behavior of Kconfig warnings.

eg: lesson 2_2 build error.

I would appreciate any suggestions or insights in to this, so that I can resolve it and thank you for your time.

Hi,

Support for nRF Connect SDK v2.9.0 in the Wi-Fi Fundamentals course is currently under development. The updated code can be found on the dev branch: https://github.com/NordicDeveloperAcademy/wifi-fund/tree/dev. Please note that this is not finished, so there might be issues.

When it comes to lesson 2 exercise 1, the exercise will be changed to use the Wi-Fi Shell sample in the SDK instead of having its own code. The exercise text has not been updated yet, but I have attached a draft of the updated text.

Okay thank you so much for the update and that makes so much sense, do you recommend any previous versions of tool chains/sdk, that I can switch back for now to work with course? (eg: ncs 2.8). Intention is to wait until they fully release/complete the updated versions, while working on stable existing tool versions.

Hi,

I recommend using v2.6.2 or v2.6.3, that is, before sysbuild was introduced since sysbuild support is part of the update that is under development.

Thank you!!

Hey Just a followup update,

I tried (lesson 2 exer 2)with 2.6.3 and still encountered errors(not Kconfig related, but Cmake), so I was curious to know if you have any thoughts on  this issue.

Cmake warnings:

The error points to file secure_fw(which Cmake warned too).

Best regards

Hi,

It seems like the issue could be related to the path length. There is a problem with CMake and path length on Windows, which will cause the build to fail if the path of files exceeds the maximum CMake path length.

Can you try moving the wifi-fund directory closer to the root directory, for example, C:\wifi-fund or C:\nordic\wifi-fund?

Best regards,
Marte

Hi ,

Thank you for the inputs that was really helpful.

Yes,you were right, it was due to path length on Windows and then  I moved the path to the similar one that you suggested and now I am not having an issue with those errors in that particular exercise in lesson 2.

But while testing and trying to give a build through the course lessons, I encountered two specific issues.

Lesson 4 exer 2: Undefined reference to Wifi_credentials during Linking

Lesson 3 exer 2: Failed secure_fw/.../crypto_init.o

3_exer 2 logs:

Do you have any suggestions on these?

Regards,

Arron

Hi Arron,

Make sure to look at the exercise page for which board target to build the exercise for. Both errors seem to be due to using the incorrect board target.
Here are the correct board targets for the two exercises:

Lesson 4 exer 2: nrf7002dk_nrf5340_cpuapp_ns

Lesson 3 exer 2: nrf7002dk_nrf5340_cpuapp

Best regards,
Marte

Thank you for the patience to find the mistake, yes it was fine afterwards.
