I finally made it with my Odroid H2+ that's keeping laying around. As DVA1622 utilizes Intel UHD onboard graphics, I would give it a try.
At first I couldn't get it working and had similar error as Neilyboy earlier, in which v1.0-beta6 and 7 I could not get the first reboot after the initial setup (no ping no discovery). I've tried even earlier beta4 and beta5 builds but none of them even get into the initial setup screen.
Then I tried to tweak with my CMOS settings, disabled Sound Card, lower Intel UHD RAM settings, and eventually found out that I've got the eMMC enabled before. Once I tuned the settings and another fresh installs, my Odroid H2+ could eventually make it ping-able and get into the DSM finally.
Of course with the DVA1622 setup, the first thing that I tested is the AI detection and make it successfully working properly, just like my genuine DVA3221. The only downsize of DVA1622 limitation is only one NIC network card is detected by DSM.
