upgrade sdkconfig from V3 to V4

Postby jumjum123 » Wed Mar 04, 2020 10:22 am

Looks like there are some changes in sdkconfig.
Is there something like a translation (manual, tool) available ?

When you build the project for the first time with a new version of IDF, all Kconfig options which have been renamed will be automatically replaced in the sdkconfig file. Backwards compatibility is also available, i.e. both old and new configuration option names can be used in code.

@ESP_igrr, thanks for your response
Please let me give a feedback
According to your mail, I did
  • my project is espressif/esp-idf-template, mainly to create libs, which are later used in my project
    copied sdkconfig from old V3.1.3 project to new V4 project
    idf.py menuconfig
    got message, Environment variable LC_ALL is temporary set to C.UTF-8
    and to run idf.py fullclean
    idf.py fullclean
    idf.py menuconfig
    got long list of changes and ignores
    checked some configuration in and looks good, at least to me. Seems impossible for me, to check all
    idf.py build
    got lot of warnings, mainly variable unused and set but not used
    once again, too much to check them all
    At the binaries and libs etc. are build, looks like a big step forward in my project
Binaries and libs etc. are build, looks like a big step forward in my project
One thing worries me at the moment, size of all binaries together is much much more compared to V3.1, which was my last step.
We'll see
