Cubietruck plus H8, Armbian image to SD card and repartitioning it after that to additional partitions !

I have Cubietruck plus H8, downloaded Armbian_5.51_Cubietruckplus_Ubuntu_bionic_next_4.17.4.img and wrote it to 32 Gb SD card.

It booted normally.

I wrote it under Windows and Paragon partition manager showed 2 partitions on the card - about 900 Mb or some looks like this and remained 32Gb-900Mb free space.

But under booted Armbian there is only 1 partition for all capacity, mounted as root.

I want to divide the one partition to root, home and for database files, for example 10 Gb for root, 5 Gb for home and 15Gb for database files.

After I did it by Paragon partition manager, booting couldn' t make at all.

That is the device is powered on shortly and then powered down.

I think the device can not find either bootloader on SD card.

Also I tried to resize partition by deleting single one, and recreating with less size starting from sector which old started from, the device is not booted up.

Is it possible and how is to make 3 partitions and booting successfully Armbian ?
