A95X F2 4/64 Multiboot script not working

[votarum]

Hi! I got stuck with multiboot setup script, would be grateful for a hint on how to solve this.

The authenticity of host '192.168.0.178 (192.168.0.178)' can't be established.
ED25519 key fingerprint is SHA256:/l86h0j+9KDb9oBrGGgq60qg8khYsKJgj4LHZcl4kx8.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Backupping current u-boot environment to uEnv.bak... [Ok]
Setup multiboot. This will reconfigure your bootloader environment to use a 'boot order' to load boot scripts while booting. The default boot order will be set to 1. sd, 2. usb, 3. emmc, 4. original boot.

This will change your bootloader environment. By doing so there is always a small risk to 'brick' your box. If you don't have the tools, image and knowledge to fix that, you should reconsider. Personally I have never 'bricked' a box with this script. However ymmv, don't blame me.
Are you sure to proceed? y/Ny
Ok, proceeding
Done.

#	WARNING: This script CAN (soft) brick your TVBOX and is UNSUPPORTED!
#
#	This script has not been tested extensively, is not high quality and makes a
#	lot of assumptions about your bootloader. If your bootloader version fails
#	to meet any of these assumptions... It will no longer boot from eMMC.
#	However, in most cases, the box will still be able to boot from a USB flash
#	drive or USB otg via the Amlogic USB burning tool. You can often use this
#	method to fix boot problems.
#
#	If you don't have the knowledge or tools to unbrick an Amlogic system and
#	you are very attached to your box, maybe this script isn't for you.
#
#	That being said, it works on my full range of boxes, S905, S905X, S905W, 
#	S912, S905X2, S922X, S905X3, S905X4 ans S905W2. I have never bricked one
#	of my boxes with this script.
#	But of course, every TVBOX can be different, so your mileage may vary.
#
#	Anyway, if you use this script, don't blame me or ask me to fix it 
#	when it goes wrong, you have been warned, you're on your own (and Google).

Error No multiboot detected. You should setup multiboot first. Run ./aml-multiboot-setup.sh and reboot.
Exit

I see on the console eMMC writing errors:

Well, I managed it lowering eMMC frequency as described here. Modified DTB attached.
