This is not correct, as per yocto documentation, this variable cannot be hand-edited, see:

   :term:`MACHINE_ARCH`
      Specifies the name of the machine-specific architecture. This
      variable is set automatically from :term:`MACHINE` or
      :term:`TUNE_PKGARCH`. You should not hand-edit
      the :term:`MACHINE_ARCH` variable.

Are you trying to share all other binaries from the rb3gen2?

I assume there are custom binaries (such as the boot firmware ones) which are specific to your hardware platform, can you confirm?

does that mean that there is no specific DTB for your board, and you are directly using the same DTB as RB3G2?

Also including a lot of dtbs that are really specific to rb3gen2, ideally yours should only contain the dtbs (and overlays) which are validated on your target.
