I still can't access the eMMC.
That's what I wrote before, it's a known issue and something I don't really plan to work on now.
Does this mean we can try the AllWinner 6 images?
Not sure what do you mean by that? Tanix TX6 is a H6 image. If you mean nightlies, then no. It will take some time. I have to clean up the code.
Small niggling thing, the Tanix seems unable to read hfs hdd's.
It's not enabled in kernel (yet).
