you should use the dtb that your kernel build produced (usually
installed somewhere in /lib/firmare/device-tree or some such)

on the pi you should copy the one your kernel produced into the
boot-assets dir of your oem/gadget snap.

this looks like your uboot.env does not run the "loadfdt" command (on
the pi's the dtb is actually loaded to 0x100 by the binary blob
bootloader that runs before uboot, we need to read it from there to make
dtb overlays work). are you using the original ?
