Hi matri

 

all i.MX6Q uSDHC ports support SDXC, interface width is

described in sect.67.1.1 Features i.MX6DQ Reference Manual
https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf

From i.MX6Q there are no restrictions on data width defined by SD specs.

Hi,

Can we directly interface through 4-bit data lines of SD card on USDHC3rd port.?

I have doubt to use 4-bit or 8-bit data lines.

My requirement is to support 256 GB SD card.

Thanks,

Manish
