I'm using a Dunfell based rootfs for our main system.  I did a hardknott build of core-image-base in order to build linux-fslc-imx 5.10.69 and when I realized fw_setenv wasn't working with Dunfell rootfs and 5.10.69 kernel, I built hardknott core-image-base rootfs with libubootenv package added to CORE_IMAGE_EXTRA_INSTALL thinking I'd copy over fw_printenv/fs_setenv and libubootenv and that would probably solve my issue ... but it doesn't include fw_printenv/fw_setenv (but libubootenv is there) in the rootfs so I don't understand what all is going on here.

Been using fw_printenv/fw_setenv since like ... forever and haven't run into something like this before that I can remember.

The binaries fw_*env is located in the package libubootenv-bin. Add that one to IMAGE_INSTALL and I hope you  get them in your rootfs.

Why wouldn't  CORE_IMAGE_EXTRA_INSTALL work to put these in rootfs like previous builds did?

CORE_IMAGE_EXTRA_INSTALL can be used as well and it will end up in IMAGE_INSTALL variable handled by core-image.bbclass. My point was that the binaries are in the package libubootenv-bin not in libubootenv. So you have to make sure you have libubootenv-bin in your IMAGE_INSTALL or another package that RDEPENDS on libubootenv-bin in order to get the binaries in your rootfs.

You got me!  In my previous build I just had libubootenv and that appeared to work for my dunfell build somehow even that release shows fw_printenv/fw_setenv to be in the libubootenv-bin package too.  Weird. 

But putting libubootenv-bin in my build did make the bins included in my rootfs now.  So one mystery solved.

Thank you!
