Using a LCD-OLinuXino-4.3TS on A20-OLinuXino-LIME2

I've got an Olimex A20-LIME2 and their 3.4" LCD with touchscreen. While they do work together using their built A20-OLinuXino-buster image, I would much rather use Armbian on this board. I've been attempting to use their lime2-lcd-olinuxino-4.3ts overlay (present commit: af1d92c). What I'm doing is, after cloning that repo to the Lime2, compile all supplied overlays with (because that's quick & easy):

make all

 

… then install the same overlay (by name) that works in OLinuXino with:

sudo armbian-add-overlay sun7i-a20/A20-OLinuXino-Lime2/lime2-lcd-olinuxino-4.3ts.dts

 

But on reboot, it fails with:

Found mainline kernel configuration
47918 bytes read in 50 ms (935.5 KiB/s)
2395 bytes read in 11 ms (211.9 KiB/s)

base fdt does did not have a /__symbols__ node
make sure you've compiled with -@
Error applying DT overlays, restoring original DT
47918 bytes read in 49 ms (954.1 KiB/s)

 

(Yes, I also gave the more generic "lime2-lcd-olinuxino.dtbo" a try too.)

 

From here, I'm at a loss for what I've been able to search around for. I did get a few clues from this discussion, but haven't managed to get this LCD to work in Armbian. I've tried the above in both:

Armbian 20.11 Stretch with Linux 4.14.87-sunxi

Armbian 5.60 Stretch with Linux 4.14.87-sunxi

 

 

I'd be delighted for any help on this effort.

Oh yes, and I also tried (as root):

mkdir -p /sys/kernel/config/device-tree/overlays/lime2-lcd-olinuxino
cat /boot/overlay-user/lime2-lcd-olinuxino-4.3ts.dtbo > /sys/kernel/config/device-tree/overlays/lime2-lcd-olinuxino/dtbo

 

Then, checked dmesg:

[ 4159.280844] OF: resolver: overlay phandle fixup failed: -22
[ 4159.280868] create_overlay: Failed to resolve tree
