Hi. Yes, we never targeted RPi-64 for the initial release so it's to be expected. The support will come soon. I don't recommend trying to hotfix it because overall many pieces of the code depend on MACHINE=raspberrypi3 for now. But it's on the list.

@pptadmin What was your reason to try to build for 64-bit?
We now build for 2 architectures (armv7, x86_64), adding a 3rd platform should be less effort now, although you probably need to add to the partition size in .wks files and ROOTFS_*SIZE variables because the 64bit binaries are larger.
