Dear All,


Hello. I have a question about sampling clock tuning by CMD19.

CMD19 sends a tuning block to the host to determine sampling point. 

Sampling clock tuning is required for UHS104 host.


How is the tuning done in i.MX6?

(I'd like to know the way of adjusting CMD in detail.)


Best Regards,
