![]() Linus Torvalds created this kernel & operating system on September 17, 1991. The kernel is the core of the operating system. Linux is a popular operating system that runs on top of the Linux kernel. This article will discuss the Linux directory structure, its hierarchies, & what file type gets stored in which directory. Also, the directory conventions might seem confusing. ![]() When someone switches from Windows to Linux systems, they might miss the C drive & D drive because Linux does not have any letter drive. So, often Windows users face the challenge while navigating the directories in Linux operating systems. Linux is a popular operating system that does not have the same directory structure as that Windows. To make this temporary modification permanent, it must be saved in a configuration fragment file (fragment-*.config) based on fragment.cfg file, and the Linux kernel configuration/compilation steps must be re-executed: bitbake.Scp /tmp-glibc/deploy/images//kernel/uImage the /boot mounting point does not exist yet, please see how to create a mounting point ![]() To make this temporary modification permanent, the delta between defconfig and defconfig.old must be saved in a configuration fragment file (fragment-*.config) based on fragment.cfg file, and the Linux kernel configuration/compilation steps must be re-executed (as explained in the README.HOW_TO.txt helper file).ģ Menuconfig and Distribution Package.Note that this use case modifies the configuration file in the Linux kernel build directory, not in the Linux kernel source directory: this is a temporary modification useful for a prototyping. Scp install_artifact/boot/uImage the /boot mounting point doesn't exist yet, please see how to create a mounting point Cross-compile the Linux kernel (please check the load address in the README.HOW_TO.txt helper file)Ĭp arch/arm/boot/uImage install_artifact/boot/.Retrieve configuration updates by comparing the new defconfig and the old one Compare the old and new config files after operating modifications with menuconfig.?: to have more information on selected line Space: hit several times to either select, select in module or unselect /: to search for a keyword, this is usefull to navigate in tree When the configuration is OK : exit and save the new configuration.Navigate forwards or backwards directly between feature.Start the Linux kernel configuration menu.Save initial configuration (to identify later configuration updates).To verify if your cross-compilation environment has been put in place correctly, run the following command:įor more details, refer to /README.HOW_TO.txt helper file (the latest version of this helper file is also available in GitHub: README.HOW_TO.txt ). config file:Ģ Menuconfig and Developer Package įor this use case, the prerequesite is that OpenSTLinux SDK has been installed and configured. Only one of these should appear in an actual. The 3 states of the main selection option for the SCSI subsystem (which actually selects the SCSI mid level driver) follow. "# CONFIG_SCSI is not set") or by the absence of the relevant line from the. The unselected state can either be indicated by a line starting with "#" (e.g. config file.Īn option indicates either some driver is built into the kernel ("=y") or will be built as a module ("=m") or is not selected. Ultimately these configuration tools edit the. Starts a character based question and answer session (Figure 1) To modify the kernel options, it is not recommended to edit this file directly. build-openstlinuxweston-/tmp-glibc/deploy/image//kernel/ config. Or config- result is located in the deploy folder: build-openstlinuxweston-/tmp-glibc/work/-ostl-linux-gnueabi/linux-stm32mp//build/. config result is located in the build folder: meta-st/meta-st-stm32mp/recipes-kernel/linux/linux-stm32mp// fragment-*.config ![]() STM32MP1 specificities are managed with fragments config files. config is the result of configuring task which is processing platform defconfig and fragment files if any.įor OpenSTLinux distribution the defconfig is located into the kernel source code and fragments into stm32mp BSP layer :Įvery new kernel version brings a bunch of new options, we do not want to back port them into a specific defconfig file each time the kernel releases, so we use the same defconfig file based on ARM SoC v7 architecture. The Linux ® kernel configuration is found in the generated file. The process of building a kernel has two parts: configuring the kernel options and building the source with those options.
