Most Common Operations Performed in Yocto - Part 1

My learnings in Yocto

1. To open the linux kernel menuconfig ( Here I am using meta-intel layer ), run the following commands

bitbake -c menuconfig linux-intel

If you are using yocto kernel it will be

bitbake -c menuconfig linux-yocto


2. To check whether your bbappend recipe is parsed by bitbake, run the following command

bitbake-layers show-appends

3. To add a particular package in your root file system

Open your local.conf file and add the recipe name below

IMAGE_INSTALL += "recipe-name"

E.g. IMAGE_INSTALL += "libusb"

or IMAGE_INSTALL_append = "libusb"

If you want this package to be included only in a particular image then,

IMAGE_INSTALL_append_pn-<image-name> = "recipe-name"

E.g. IMAGE_INSTALL_append_pn-core-image-sato = "libusb"

4. To include a kernel module in your root file system

MACHINE_ESSENTIAL_EXTRA_RDEPENDS += "kernel-module-cp210x"

5. To automatically load the module on boot

KERNEL_MODULE_AUTOLOAD += "cp210x"

bb.utils.contains yocto

bb.utils.contains  is most commonly used function in Yocto. grep in poky directory returned with 696 count. $ grep -nr 'bb.utils.contains' poky/ | wc -l 696 It's definition is present in 'poky/bitbake/lib/bb/utils.py' file This function returns third argument if the second argument is subset of the first argument else returns fourth argument Let's take an example to understand this. You can see from the above screenshot, when the second argument is a subset of first argument, "present" was returned, else "notpresent" was returned We can also use bb.utils.contains inside if loop. This we can use inside a recipe. if ${@bb.utils.contains('SOMEFLAG','NEWVALUE3','true','false',d)}; then     FOO = 'HELLO' fi

make config vs oldconfig vs defconfig vs menuconfig vs savedefconfig

Building the Linux Kernel is a two-step process: Configuring the Kernel options Building the Kernel with those options. There are many methods available for configuring the kernel. make config: Text-based Configuration.  Options are prompted one after another. All options need to be answered Access to former options is not possible make menuconfig: Menu-driven user interface Allows to navigate forwards and backward directly between features Allows to load and save files with filenames different from ".config" Provides search feature It uses ncurses library for GUI. If the ncurses library is not installed, make menuconfig option fails. To install ncurses library on Ubuntu: sudo apt-get install libncurses5-dev make defconfig: Creates a ".config" file with default options from the ARCH supplied defconfig Configurations are generally stored in the directory: arch/$(ARCH)/configs $ ls arch/x86/configs/ i386_defconfi

PR, PN and PV Variable in Yocto

-
PN : Represents the name of the recipe. The name is usually extracted from the recipe file name. PR:  Represents the revision of the recipe. Default value for this revision is "r0". Subsequent revisions of the recipe conventionally will have "r1", "r2" and so on. PV:  Represents the version of the recipe. Normally extracted from the recipe file name. For example: ffmpeg_3.4.2.bb recipe. ${PN} : ffmpeg ${PV} : 3.4.2
