menuconfigESP-IDF uses kconfiglib which is a Python-based extension to the Kconfig system which provides a compile-time project configuration mechanism. Kconfig is based around options of several types: integer, string, boolean. Kconfig files specify dependencies between options, default values of the options, the way the options are grouped together, etc. For the complete list of available features please see Kconfig and kconfiglib extentions. Application developers can open a terminal-based project configuration menu with the idf. After being updated, this configuration is saved inside sdkconfig file in the project root directory. Based on sdkconfigapplication build targets will generate sdkconfig. For the legacy GNU Make build system, the project configuration menu is opened with make menuconfig. In some cases, such as when sdkconfig file is under revision control, the fact that sdkconfig file gets changed by the build system may be inconvenient. The build system offers a way to avoid this, in the form of sdkconfig. This file is never touched by the build system, and must be created manually. It can contain all the options which matter for the given application. The format is the same as that of the sdkconfig file. Once sdkconfig. Project build targets will automatically create sdkconfig file, populated with the settings from sdkconfig. Note that the build process will not override settings that are already in sdkconfig by ones from sdkconfig. For more information, see Custom sdkconfig defaults. The following attributes of Kconfig files are standardized:. Within any menu, option names should have a consistent prefix. The prefix length is currently set to at least 3 characters. The indentation style is 4 characters created by spaces. All sub-items belonging to a parent item are indented by one level deeper. For example, menu is indented by 0 characters, the config inside of the menu by 4 characters, the help of the config by 8 characters and the text of the help by 12 characters. Lines cannot be wrapped by backslash because there is a bug in earlier versions of conf-idf which causes that Windows line endings are not recognized after a backslash. The checker checks all Kconfig and Kconfig. Please note that the checker cannot correct all rules and the responsibility of the developer is to check and make final corrections in order to pass the tests. The standard Kconfig tools ignore unknown options in sdkconfig. So if a developer has custom settings for options which are renamed in newer ESP-IDF releases then the given setting for the option would be silently ignored. Therefore, several features have been adopted to avoid this:. As the consequence, the settings for old options will be kept and not ignored. Old options are replaced by new ones in the sdkconfig file. This is done in order to not break customer codes where old option might still be used. Deprecated options and their replacements are automatically generated by confgen. Note that depending on the options selected, some options listed here may not be visible by default in the interface of menuconfig. By convention, all option names are upper case with underscores. When Kconfig generates sdkconfig and sdkconfig. Found in: SDK tool configuration. The default setting assumes a crosstool-ng gcc setup that is in your PATH. This causes make to print a warning any time an undefined variable is referenced.

Following that, and UG for petalinux installation and other reference, I want to load linux on the PS using petalinux as the example in UG suggests on page number I followed all the steps for installation mentioned in UG and the steps to design the hdf file as mentioned in UG but when I am running the command to configure it ends up giving following error and I am not getting how I can resolve this or what is causing this error. Yes, the hdf file is at that location. Also I rechecked the libraries required for petalinux as well, they are also to their latest required version as mentioned in UG I looked into the config. Could you help in explaining and resolving through this. It must be at least 19 lines by 80 columns. It is working now, seems the terminal size was the issue. I just maximized the terminal screen and executed the same command and it worked which earlier was not working when my terminal was not maximized it was just a small window over other window as well. This happened to me as well. The PetaLinux installation is prone to errors and is flaky at best. It just happened to me with Sign In Help. Turn on suggestions.

Due to the current COVID pandemic, we have increased the capacity for each congregation to connections. No action is required on your part to use the additional capacity. It is used around the world to assist elderly, infirm and ill members to enjoy congregation meetings they are unable to attend in person. Users connect to KHCONF via web browser after receiving an invitation to join a particular congregation's meeting online, using a computer, tablet or smartphone. If the user does not have enough Internet bandwidth to view the full video stream, they can choose to listen into the audio portion only. In some locations, users without Internet service can connect and listen into the meeting by calling a local telephone number. This feature is available in about 50 countries around the world. In some countries, KHCONF also offers an audio-only service, where participants connect via Internet connections, using a computer or mobile device apps. This audio-only service requires far less bandwidth than the standard integrated audio and video streaming service. Where available, a local phone number can be added to the subscription for callers with no Internet connection. In locations where obtaining a local phone number for our service is impossible or cost-prohibitive, all users must connect via Internet connections and smartphone or PC-based apps.
