I have a NanoPi Neo Core with eMMC..I have installed armbian os from "https://www.armbian.com/nanopi-neo/" to sd card and tried the "Armbian configuration utility" and "nand-sata-install" to install os to eMMC. But it is showing "there are no targets..please check your drives."..If we give "fdisk -l" command it is not detecting the eMMC.

How to solve this issue??

For friendlycore "eflasher" will work(I have tried that).But for armbian it is not detecting the eMMC.

@J, back to armbian developers or their forum to find out if they plan support.
