Figure Out PetaLinux Yocto Version (PetaLinux <= 2019.2)
Note: This guide is for PetaLinux version 2019.2 and older. For PetaLinux version 2020.1 and newer, see this newer post.
This post shows you how to figure out which version of Yocto is being used in a particular version of PetaLinux Tools (PetaLinux Tools 2018.2 is using Rocko 2.4.1).
Versions Used
PetaLinux Tools 2018.2
Steps
1. Type cd /opt/pkg/petalinux
2. Type find . -name poky.conf
You’ll see the following output:
./components/yocto/source/arm/layers/core/meta-poky/conf/distro/poky.conf
./components/yocto/source/microblaze_lite/layers/core/meta-poky/conf/distro/poky.conf
./components/yocto/source/microblaze_full/layers/core/meta-poky/conf/distro/poky.conf
./components/yocto/source/aarch64/layers/core/meta-poky/conf/distro/poky.conf
Note: this implies that PetaLinux Tools 2018.2 ships with 4 copies of Yocto.
| 3. Type **find . -name poky.conf -print0 | xargs –null grep -HEi ‘DISTRO_CODENAME = | DISTRO_VERSION =’** to list the DISTRO_VERSION and DISTRO_CODENAME for all 4 of the Yocto copies shipped with PetaLinux Tools |
You’ll see the following output:
./components/yocto/source/arm/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_VERSION = "2.4.1"
./components/yocto/source/arm/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_CODENAME = "rocko"
./components/yocto/source/microblaze_lite/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_VERSION = "2.4.1"
./components/yocto/source/microblaze_lite/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_CODENAME = "rocko"
./components/yocto/source/microblaze_full/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_VERSION = "2.4.1"
./components/yocto/source/microblaze_full/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_CODENAME = "rocko"
./components/yocto/source/aarch64/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_VERSION = "2.4.1"
./components/yocto/source/aarch64/layers/core/meta-poky/conf/distro/poky.conf:DISTRO_CODENAME = "rocko"
This means that PetaLinux Tools 2018.2 is using Rocko 2.4.1.
With this, the specific documentation for the release can be listed at [link] by selecting YP CORE - ROCKO 2.4.1.
