Most of the root file system menu config is static. These are the utilities that are supported by Xilinx. You can add your own layers in a project or add existing additional recipes from the existing layers in PetaLinux. Layers in PetaLinux can be found in <plnx-proj-root>/components/yocto/layers.
iperf3 is not in the root
file system menuconfig. The following example demonstrates adding the
iperf3 into the root file system menuconfig.
- The location of the recipe is <plnx-proj-root>/components/yocto/layers/meta-openembedded/meta-oe/recipes-benchmark/iperf3/iperf3_3.2.bb.
- Add the following line in <plnx-proj-root>/project-spec/meta-user/conf/user-rootfsconfig.
petalinux-config -c rootfs.
- Select . Enable it, save and exit.
petalinux-build.Note: It is your responsibility to add the recipes in the layers available in PetaLinux tools, apart from PetaLinux default RootFS menuconfig.Note: The above procedure is applicable only to the recipes from the existing layers.
petalinux-image-fullhave sstate locked. To unlock you have to add
SIGGEN_UNLOCKED_RECIPES += "my-recipe"in project-spec/meta-user/conf/petalinuxbsp.conf.
For example, you have changes to be made in mtd-utils package, so you have created a .bbappend for the same without SIGGEN_UNLOCKED_RECIPES += "mtd-utils" in project-spec/meta-user/conf/petalinuxbsp.conf. During project build, you should see the following warning. Your changes for the package are not included in the build.
