Hi all,

I'm using i.MX6Q L3.0.35_4.1.0 freescale release in my project.

I need to test UHS-1 Micro SD card in my custom board.

Please let me know is this code release supports this feature?

If not what changes to be done in code as well as board to support this feature.

Thanks and Regards,

Nithin

latest BSP:

Hi Igor,

I need to test UHS-1 DDR50 mode in my board.

Is this support also not present in Linux 3.0.35 kernel of L3.0.35_4.1.0 release?

Thanks and Regards,

Nithin

Hi Igor,

Is there any patch file present for Linux 3.0.35 to support UHS-1 in it.

Thanks and Regards,
