IMX6 platform SDK SD3.0 card support

[sergeydanilov]

Hello,

Is it possible to work with sd card in UHS-I SDR104 mode (104 MB/s max) using current platform SDK 1.1.0?

in "i.MX 6 Series Firmware Guide" I found the following text (page 348):

For the card initialization process, configure the uSDHC clock as follows:

• Identification frequency ≤ 400 KHz

• Operating frequency ≤ 25 MHz

• High frequency ≤ 50 MHz.

and no any info about SDR104 mode etc.

From :

imx6 is compatible with the SDIO Card Specification version 3.0. So it should able to support SDR104.
