Q: [Translated by Google]: I made a compatible iMX6D and iMX6Q board, but I found iMX6D (MCIMX6D5EYM10AC-QCD1602) does not support SATA-II, but iMX6Q support, I think my hardware is no problem. However, according to the official note, iMX6D should support SATA-II, which is why?
A: iMX6D has the same SATA module as iMX6Q and it also supports SATA-II.
Please try to adjust sata signal shape described in sect.36.4.14 GPR (IOMUXC_GPR13)

May be recommended to perform sata eye pattern test:
The power level in SATA_VP pin is higher (1.28V) than normol (1.1V), how to lower the power level to normal? will this degrade the performance or destroy the IC ？
