Hi all

I have a question about routing length of SD card I/F in i.MX6SX.

The length between SD card and i.MX6SX is long in my system.

Is there limitation on routing length of SD card I / F in i.MX6SX ?

Or do you have any information for recommendation for SD card development ?

Hi Ko-hey

there are no strict limitations and recommended to use ibis modelling.

Just for reference please refer to sect.3.6.8 High speed signal routing recommendations
