Hi I wonder if it is possible to update bitbake/update the version. I have a .bb recipe which I haven't written myself and I don't know how to downgrade the way it is written. The problem is that the version of bitbake which comes with petalinux doesn't have the bb.utils.filter function. Which is provided by newer versions of bitbake.
I tried to download a new version and replace the one found in yocto/aarch64 in the petalinux source directory but this only resulted in cannot source bitbake. So I wonder if you have any tips for an upgrade path or ways to upgrade bitbake.
