Hi, I would say you are hitting some kernel problem here. Please can you try - use new cryptsetup versision (1.7.1) - if dmestup works, please show the exact difference in mapping table. (My guess it is only in offset reserved for header - you will need to decrease device size as well. We are probably hitting some kernel bug when start of crypt device is not aligned to mmc block.) Could you try to create exact mapping table as LUKS does? (Just activate LUKS using cryptsetup, check dmsetup table --showkeys and repeat it with dmsetup.) If you still see the problem, then kernel is the source of problem. Anyway, there were a lot of changes related to aarch64, so if you can use more recent kernel, it would be nice as well. (According to log you are using Linux 3.18.21-tegra aarch64.)
