@gkkpch can you please correct that link?
Edit: is it the same as this: https://lore.kernel.org/patchwork/patch/1038299/ ?
Edit2: here they even talk about disabling it for the A64: https://www.spinics.net/lists/linux-mmc/msg61280.html
Hmm, the problem seems to be that in my case on the clusterboard it actually seems to work better with the HS DRR mode (but better in the sense that it is still broken), if as by default in Armbian only "mmc-hs200-1_8v;" is set and thus apparently no drr mode used, the emmc fails completely in my case.
