Unfortunately, this does not apply to my case 😞. I opened a specific ticket for this so i'm giving details and tests there.

Hi JONATHAN LL

i would like to add these spaces, but i'm note sure to have detected the file where i need to do it. Can you provide me a specific path to check? All the VERSION files i found already have spaces before and after "="

I was able to fix the issue by changing how/when my mcuboot.conf was included.

In previous NCS versions I appended my mcuboot.conf in app/CMakeLists.txt:

...
list(APPEND mcuboot_OVERLAY_CONFIG "${CMAKE_CURRENT_SOURCE_DIR}/mcuboot.conf")

SET(mcuboot_CONFIG_BOOT_SIGNATURE_KEY_FILE "\"${CMAKE_CURRENT_SOURCE_DIR}/keys/private/boot-ecdsa-p256.pem\"")

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
...

It think appending the conf file before finding the Zephyr package was causing the issue. I changed my app/CMakeLists.txt to this:

...
SET(mcuboot_CONFIG_BOOT_SIGNATURE_KEY_FILE "\"${CMAKE_CURRENT_SOURCE_DIR}/keys/private/boot-ecdsa-p256.pem\"")
SET(mcuboot_CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256 "y")

find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
...

and I moved my mcuboot.conf file to app/child_image/mcuboot.conf so West knows it belongs to the MCUBoot child image.

Now MCUBoot builds without issue.

did you add the spaces like Marko W did ?

I am not able to replicate the issue as you describe here in this post.

Hi Jonathan,

any news about this issue? I read the posts following this one, but i am not able to come out of this error, even with the last 2.5.2 (2.4.2 working).

I tried to fix this error adding the VERSION file (filled as docs says) to the same folder of prj.conf together with #include <app_version.h> but absolutely nothing changed.

I have now found the cause.

Contrary to the example in the documentation Application version management I had no spaces before and after the "=".

If I insert spaces, then I can compile even if the VERSION file exists.

Can anyone confirm this...?

If you track the error to the file (version.cmake) you will notice that the error happens because the compiler can't find the definitions you're speaking about. I think that is the connection if it is what are you're trying to understand

Sorry for the late reply...

I have now tested several projects and this error only occurs in one project. Two other projects can be updated from 2.4.0 and 2.4.2 to 2.5.0. There are more warnings here, but the build process is running through (firmware not yet tested).

When comparing the projects, I noticed that I have a "VERSION" file in the project folder. I had already prepared this based on the documentation (Application version management).

~~~
VERSION_MAJOR=0
VERSION_MINOR=5
PATCH LEVEL=0
VERSION_TWEAK=0
EXTRAVERSION=unstable
~~~

If I remove this file I can successfully run a build with 2.5.0 (firmware not tested yet).

However, I can't really understand the connection to the error message...

Thanks Frax, will test and report interlay.

Hi Jonathan,

i'm not able to recall all the samples tested because a lot of experiments, but i spent a bit of time to prepare something you can test on:

Here the samples/configurations i tested:

- "hello world" for both nrf5340dk_cpuapp and nrf5340dk_cpuapp_ns target --> ERROR on version.cmake (the same Marko W made the post for)

- "peripheral_hr" for both nrf5340dk_cpuapp and nrf5340dk_cpuapp_ns target --> WORKING

Toolchain: 2.5.0

SDK: 2.5.0

I hope this helps,

Frax

Can you give me a list of what samples you have tested.

I have the very same error for my project. The code compile and works correctly with SDK 2.4.2 and throw this error in 2.5.0. I get the same error for all the 3 different sample projects i tried compiling for both my custom board (nrf5340 based) and nrf5340DK

Does this happen with only one application or are you able to reproduce the error on other samples?
