i.MX8 QXP DDR3L-1866 validation board schematic

Hello,

I am developing a board with the IMX8X QXP processor. We use DDR3L memory with ECC. I follow your hardware recommendation (i.MX8 QM / i.MX8 QXP Hardware Developer’s Guide) but I have a few questions:
- Could you have the source (brd + schematic) of i.MX8 QXP DDR3L-1866 validation card?
- What is the recommendation for the series resistance value for the differential pair CLK? (same resistor for command / address traces)?
- What is the recommendation for the value of the VTT capacitor ?

Thank you.
Best regards,
Vincent MASSONNEAU.
