I downloaded starfive-jh7110-202302-eMMC-minimal-desktop.img.bz2 as described and linked here:
Unfortunately, it seems that my new eMMC died and my eMMC to Micro-SD adapter got lost before I could test the current image. But over the course of today, two eMMC should arrive, as well as an eMMC to Micro-SD adapter and a USB 3.1 to eMMC adapter. I have to work a night shift tonight and will probably not be able to report until tomorrow morning.
