Connecting iMX.6 to SD card

[avishefi]

Dear Sir,

I have a problem connecting iMX.6 to SD card.

Is there layout guidelines?

The length of clk and 4 data is about 10000 mil, clk=50Mhz.

The difference of the length between data and clk is less than 450 mil.

Best Regards

You can refer to chapter 3.6.8 "High speed signal routing recommendations" of the Hardware Development Guide:

All synchronous modules should have bus length matching and relative clock length control.
- For SD module interfaces:
- Match data and CMD trace lengths (length delta depends on bus rates)
- CLK should be longer than the longest signal in the Data/CMD group (+5 mils)
