Gives a flash dump for the Eufy Home Base 2 here: https://anonymousfiles.io/Ve9y3cL4/
With this partition table:
[ 0.472000] Creating 12 MTD partitions on "raspi":

But binwalk, file, unsquashfs, etc., can't seem to find filesystems at those offsets. Eg., binwalk just sees a bunch of xz data (which often decompresses into MIPS binaries, but not a filesystem):
$ binwalk mtd0 |head

I'd like to study the various rootfs filesytems listed in the partition table. What am I missing?
