Using SDK generated by Yocto

-

SDK Can be generated by running "bitbake -c populate_sdk <image_name>" command.

E.g. bitbake -c populate_sdk core-image-sato

Once the command is successfully generated, the SDK (poky-glibc-…-toolchain.sh) is present in build/tmp/deploy/sdk folder

To use the SDK, you should run the environment script.

 $ . /opt/poky/2.5/environment-setup-corei7-32-pokymllib32-linux

 $ . /opt/poky/2.5/environment-setup-corei7-64-poky-linux

E.g. $ source /opt/poky/2.5/environment-setup-corei7-32-pokymllib32-linux

This will set the Compiler,  and all the flags

$ echo $CC
i686-pokymllib32-linux-gcc -m32 -march=corei7 -mtune=corei7 -mfpmath=sse -msse4.2 --sysroot=/opt/poky/2.5/sysroots/corei7-64-poky-linux

$ echo $CFLAGS
-O2 -pipe -g -feliminate-unused-debug-types

$ echo $LDFLAGS
-Wl,-O1 -Wl,--hash-style=gnu -Wl,--as-needed

To compile a program, run the following command

$CC hello_world.c -o hello_world

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

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
