I realize this is probably more of a Kconfig question, but it's ESP-IDF I have this problem with.

Whenever I build my ESP-IDF project (containing custom Kconfig projectbuild configurations), I get bogus changes in the sdkconfig like that:

 CONFIG_IDF_EXPERIMENTAL_FEATURES=y

No substantial changes, but a block of configurations gets removed from somewhere and put to another location.

Is that a known problem and is there a fix? It really disturbs my diffs.

Here is one suggestion but I didn't get any response if it helped or not: https://github.com/espressif/esp-idf/is ... 2036568548

Thanks, I commented on this post. Sadly, the suggested fix does not change anything for me. An `idf.py build` still mixes up a section.

I wonder... if the order of components in `sdkconfig` is not relevant, perhaps I could add a post-build line (via cmake?) that just sorts the `sdkconfig` line-by-line?

This is not a problem with line endings or similar problems.
Obviously something is enabling and/or disabling some options in Kconfig. Do you have some extra build scripts?
Maybe rebuild with set-target is doing this?
Its rather not possible, but different targets may have different default sdkconfig options.
For example S2 does not have BLE, so the options related to bluetooth may be disabled (just example).

Sounds like sdkconfig.defaults should be the solution to this problem.
In short, you menuconfig your project as desired (->sdkconfig), then idf.py save-defconfig to create an sdkconfig.defaults from the current sdkconfig, add sdkconfig.defaults to version control, and discard the original sdkconfig.
