I tried that, following this procedure
- flash minimal image to SD-card
- boot from SD-card
- sudo apt install armbian-config
- launched armbian-config
- selected nand-sata-install
This is not working because required space on eMMC was not enough
I solved flashing the image directly on eMMC, resizing manually and then installing armbian-config.
I had to install the required packages first, dividing them in few groups, cleaning up (apt clean && apt autoclean && apt autoremove) and then install armbian-config
Trying to install armbian-config directly was failing because the space was not enough
