Thanks,

I know. But I was not sure if the MMC 4.5 compliant controller is backward compatible to eMMCs compliant to 4.41. So I wanted to go sure that there are no known Issues with Version 4.41 eMMCs an LS1021.... . My custom designed board is currently in production, so for a few days I have still the chance to change the BOM. I don't need the security features but plan to boot from eMMC.
