Cmake Error "Math cannot parse the expression" with NCS > 2.4.2

Hello,

i'm using nrf connect sdk 2.4.2 to develop the firmware for my custom nrf5340 board without issues. I'm trying to upgrade to the the latest release but both 2.5.0 and 2.5.2 gives me this error when trying to compile:

CMake Error at D:/Nordic/v2.5.0/zephyr/cmake/modules/version.cmake:74 (math):
math cannot parse the expression: "( << 16) + ( << 8) + ()": syntax error,
unexpected exp_SHIFTLEFT (4).

I found THIS issue on DevZone that is extremely similar to my one and posted there some material to test on, but i didn't get any feedback in few months. For this reason, i'm opening a new issue.

The issue is clearly correlated to the Application versioning, but even reading the docs and making some tests i was not able to solve it.

Any suggestion?

Frax

I'm a bit at a loss here. Could you upload your project so I can have a look?

Just to summarize

New version of the SDK

new sample project with only hello world and no changes? Are you including any file named version in your project folder? I don't believe are you, just need to check.

Could you generate the support information from vscode and post it here?

Regards

Runar

NB: Due to public holidays here in Norway, we will be out until the 2. of April.

Hi runsiv,

Correct, new version of SDK and toolchain. Project with only hellow world and no changes. I am NOT including any file named version in my project folder.

Here follows the support information generated from vscode:

Hi, I know I have asked before, but could you post the version file located in your ncs/v2.6/zephyr/ folder?
The developers are asking for it so just running through all steps here

By the way, Have you tried to delete the build folder after you changed SDK version? It sometimes fixes strange issues.
I also got a request for the VERSION file itself, if you could upload and not copy paste it would be great

Hello,

The CMake script is clearly failing to read the version assignments from the VERSION file, but I don't understand why. I don't encounter this issue when I build a project with your file either. So, this issue doesn't appear to be related to the one discussed in the linked ticket, where the culprit seemed to be an invalid VERSION file (missing whitespaces).

To see if this might be an issue with the SDK files, please try to open a terminal in VS Code by pressing Ctrl+Shift+P to open the command palette. Then, type nRF Connect SDK: Open Toolchain Terminal Profile followed by Enter to open the terminal.

From the opened terminal, change the directory to 'nrf', and type git branch to verify you are on the v2.5.x branch. Then, enter west update to ensure all repositories are aligned with the revisions from the west manifest.

Can you please confirm what you mean with "change the directory to "nrf"? I have my sdk branches in "C:/ncs". If i type "cd nrf" i get errors.

Did you open the terminal as I explained above? It should open in the current SDK root directory. E.g., C:/ncs/v2.5.2/
