In your previous email your advice was:
KERNEL := kernel-bin | append-dtb | lzma
The difference is patch-dtb against append-dtb.

With the current change in the target/linux/ramips/image/rt305x.mk :
+ KERNEL := kernel-bin | patch-dtb | lzma IMAGES := factory.bin
+ IMAGE/factory.bin := \
+ append-kernel
I'm able (after make distclean, make menuconfig, make) to find in
bin/targets/ramips/rt305x/ the image
lede-ramips-rt305x-dwr-512-b-squashfs-factory.bin
This seems to be exactly what I'm looking for (vmlinux lzma compressed with
device tree embedded).

This cmd works as expected.
Thanks,
I'm going to test the new fw.
