Answer 1

How to find out Yocto version?

Check out this file it gives you full details about Yocto version

vim $POKY-DIR/meta-poky/conf/distro/poky.conf

You will get info like:

DISTRO = "poky"
DISTRO_NAME = "Poky (Yocto Project Reference Distro)"
DISTRO_VERSION = "2.7.2"
DISTRO_CODENAME = "warrior"
SDK_VENDOR = "-pokysdk"
SDK_VERSION = "${@d.getVar('DISTRO_VERSION').replace('snapshot-${DATE}', 'snapshot')}"
.....
.....

Now you will know the version you are actually using.

To find the kernel version you are using:

bitbake -e virtual/kernel | grep "^PV"

Answer 2

• To know the yocto kernel version you are using, just type bitbake -e virtual/kernel | grep "^PV"
• And to know the kernel you are using, type bitbake -e virtual/kernel | grep "^PN"

And if you have any kernel you want to know the version, type bitbake -e <kernel_name> | grep "^PV"

I hope this will be helpfull

Answer 3

An easier way to get this together with some other yocto related information without launching bitbake is doing the following

 cat $POKY-DIR/documentation/poky.ent | grep "DISTRO_REL_TAG"

To know DISTRO info

cat $POKY-DIR/documentation/poky.ent | grep "DISTRO*"

To know POKY info

cat $POKY-DIR/documentation/poky.ent | grep "POKY*"

To know YOCTO info

cat $POKY-DIR/documentation/poky.ent | grep "YOCTO*"

Answer 4

cd poky
grep "DISTRO_" meta-poky/conf/distro/poky.conf
